AnHui JuanKuang Electric Co., Ltd. is a China-based Refrigerator Capacitors manufacturer producing metallized polypropylene run capacitors for refrigerator and refrigerator-compressor motor circuits. Since 1995 we have built a complete film capacitor chain in-house, from metallized film production through winding, welding, spray coating, assembly and testing.
Our Position in Refrigerator Capacitors
As a Refrigerator Capacitors Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
Refrigerator capacitors provide the starting torque and running-phase shift that a single-phase compressor motor needs, then hold that performance across years of continuous duty, wide ambient swings and repeated compressor cycling. Our range covers the two mounting conventions used on compressor circuits: cylindrical cans for clamp or strap mounting and rectangular plastic cases for compact terminal-side installation.
The CBB65 family is the core of this range. Each capacitor is wound from metallized polypropylene film, with self-healing behaviour that clears local film defects under voltage rather than failing the whole element. We produce the film ourselves, which keeps dielectric thickness, metallization pattern and winding tension under one quality system.
Refrigerator Capacitor Range
Three product families cover the refrigerator and compressor applications we support. Each is offered with custom capacitance, voltage rating, lead configuration, case finish and packaging under OEM and ODM programmes.
| Product |
Case Construction |
Typical Fit |
Mounting & Termination |
| CBB65 / CBB65A Cylinder Plastic Case |
Round plastic can, resin-sealed end |
Compressor run/start circuits, general appliance builds |
Clamp or bracket; dual fast-on terminals |
| CBB65 Aluminium Case |
Aluminium can for higher thermal dissipation |
Continuous-duty compressors, warmer condenser compartments |
Metal clamp; welded or riveted terminal cover |
| CBB61 Square Plastic Case |
Rectangular flame-retardant plastic box |
Compact fan and small compressor motors, control-box builds |
Screw tab or adhesive fixing; lead wire or pin terminals |
Cylinder and square formats differ in how heat leaves the element and how the part sits in the appliance. A compressor compartment that already runs warm favours the aluminium can for its heat path; a tightly packed control box usually needs the square plastic case for its smaller footprint.
Specifications That Define a Refrigerator Capacitor
A proposal for this category is built around the electrical and mechanical working point, not a catalogue part number alone. We confirm the following values with each customer before releasing a sample or a production lot.
- Capacitance and tolerance — matched to the compressor nameplate value and the tolerance band the motor design allows.
- Rated AC voltage and frequency — 50/60 Hz operation, with headroom for mains variation in the destination market.
- Operating temperature range — selected against the real compartment temperature near the compressor, not the room ambient.
- Dissipation factor and insulation resistance — controlled as routine outgoing parameters.
- Terminal type and spacing — fast-on tabs, lead wires with connectors, or pins, in the orientation the harness expects.
- Case dimensions and fixing — clamp diameter, bracket holes, tab positions and overall height.
- Safety construction — internal overpressure disconnection on cylindrical types and flame-retardant case material.
Capacitance drift over life affects compressor starting more than most buyers expect: a motor that starts reliably at the nominal value may struggle near the low end of the band in a cold cabinet. We hold the winding count and film tension to keep the delivered value centred in the agreed window.
Manufacturing and Quality Control
Our integrated plant covers metallized film production on German coating equipment, Swiss automatic winding machines, automated welding, spray coating, assembly and automated testing, with a 2,000 m² R&D and testing centre and a 53,000 m² production site. Because film, winding and finishing sit in one layout, a change in dielectric specification is controlled at the source rather than negotiated between suppliers.
- Incoming raw material inspection ahead of every production run.
- Process parameter control and in-line inspection at winding, welding and coating.
- Semi-finished and finished product testing, including 100% final inspection.
- Shipment quality control with lot traceability to the production batch.
We operate to ISO9001 and ISO14001, and our capacitor products hold UL, VDE, CE and CQC certification, which supports market access in North America and Europe. CBB65 AC motor capacitors obtained VDE A-level certification in 2015. All capacitor products comply with RoHS, REACH, TSCA and POPs requirements, and we issue the corresponding compliance statement for destination-market customs and product stewardship files.
Installation, Safety and Serviceability
Refrigerator Run Capacitors sit on a live motor circuit and must be treated as such during assembly. We supply parts with discharge and handling guidance, and we design terminal geometry so the harness cannot be rotated onto the wrong tab during line assembly.
- Discharge before handling; verify zero voltage at the terminals after removal from service.
- Mount so the case is not loaded by the wiring harness and the terminals stay free of stress.
- Keep the can clear of compressor discharge piping and other heat sources; the aluminium case is more tolerant of a warm compartment but not of direct contact with hot lines.
- Match replacement capacitance and voltage exactly on service interventions; never substitute a higher value to cure a start problem.
- Inspect terminals and case for swelling or leakage as part of scheduled appliance maintenance.
For production customers, we can prepare packaging in the bulk or tray format your line requires and identify carton markings and quantities so incoming inspection matches your receiving process. Capacitance, voltage, dimensions and packaging are all customizable, and we support full OEM and ODM development from drawings or samples.
Where Our Capacitor Range Fits
Refrigerator Run Capacitors are one branch of our AC motor capacitor output. Appliance and refrigeration manufacturers working across several product lines often source the whole motor capacitor set from one programme, which keeps dielectric specification, marking and compliance documentation consistent across the platform.
- AC Motor Capacitors — the parent family covering compressor, fan and pump motors.
- Washing Machine Capacitors — wash and spin motor duty with different cycling patterns.
- Air Conditioner Capacitors — compressor and outdoor fan applications.
- Fan Capacitors — small motor start and run duty in appliance air paths.
Compressor capacitors are also supplied as long-term stable volume to air conditioner and refrigerator compressor programmes, with annual export volume above 10 million units.

Yes. Custom production is our core business. We develop and manufacture to customer drawings or samples, including capacitance value, rated voltage, terminal configuration, case dimensions, marking and packaging. OEM and ODM programmes are fully supported from prototype through volume release.
What certifications support refrigerator capacitor exports?
Our products hold UL, VDE, CE and CQC certification, and our CBB65 AC motor capacitors obtained VDE A-level certification in 2015. We work under ISO9001 and ISO14001, and all capacitor products comply with RoHS, REACH, TSCA and POPs requirements, with a compliance statement available for destination-market documentation.
How is quality controlled on refrigerator capacitor production?
We apply full-process quality management. Raw materials are inspected on receipt, process parameters are controlled at winding, welding and spray coating, semi-finished parts are tested between stages, and finished capacitors undergo 100% final inspection against customer requirements and international standards before shipment release.
Can you match a capacitor to an existing compressor circuit?
Send the compressor nameplate rating, the original capacitor marking or a physical sample, the compartment temperature near the mounting point, and the terminal and fixing details. We match capacitance, voltage class, case format and terminal geometry, then confirm the configuration before sample production.
What are the supply terms for volume refrigerator capacitor orders?
Trade terms such as FOB and CIF are confirmed during quotation. For mass production we normally require a 30% advance payment with the balance against a copy of the bill of lading. T/T is the main payment method, and L/C can be negotiated. Shipments move mainly by sea, with air freight via Ningbo or Shanghai airports for urgent deliveries.
