◆ Product Advantages
- Square Plastic Case Design with Strong Multi-Scenario Installation Adaptability: CBB61 series square plastic case capacitors have a regular shape that can be directly fixed to fan motor wiring compartments, support frames, or dedicated mounting slots, flexibly adapting to the diverse installation requirements of ceiling fans, desk fans, wall fans, ventilation fans, exhaust fans, and other fan product types, with easy installation and high space utilization
- S0 and S3 Dual Safety Levels Available Covering Different Safety Requirements: Provides two safety level specifications — S0 (non-explosive design) and S3 (safety film anti-explosion structure); S0 is suitable for fan applications with conventional safety requirements, while S3 uses a safety film anti-explosion structure where the safety valve actively releases pressure upon abnormal failure for further enhanced safety; customers can flexibly select based on target market and safety certification requirements for fan products
- Full Epoxy Resin Sealing for Outstanding Protection Performance: Square flame-retardant plastic housing with full epoxy resin sealing process provides moisture-proof, vibration-proof, and corrosion-resistant protection, effectively addressing long-term fan use in high-humidity and complex environments such as kitchens, bathrooms, and outdoor locations, ensuring stable and reliable electrical performance
- Low Dissipation with High Insulation Resistance for Excellent Electrical Performance: Extremely low product dielectric dissipation factor (tanδ) and high insulation resistance ensure minimal energy loss during fan motor starting and running, with high motor operating efficiency, minimal unit heat generation, and extended fan service life
- Good Self-Healing Property with Strong Overload Capability: Metallized polypropylene film self-healing characteristic effectively prevents early failures from occasional localized breakdown; strong overload capability meets current impact requirements during fan startup moments and frequent low-speed/high-speed gear switching

◆ Key Selling Points
- Mainstream Standard Model in the Fan Industry with Strong Universality: CBB61 is one of the most widely used capacitor models in the fan industry, with products highly compatible with major domestic and international fan and home appliance brands, convenient procurement, easy replacement, and the preferred product for both manufacturers and the maintenance market
- Improved Fan Starting Reliability and Operating Efficiency: Premium CBB61 capacitors significantly improve fan motor starting phase shift characteristics, reducing startup failure rates, improving full-speed operating efficiency, simultaneously reducing motor operating noise and enhancing user experience
- S3 Safety Film Anti-Explosion Meeting Export High-Safety Standard Market Requirements: S3 products comply with safety requirements for fan home appliance capacitors under European CE, North American UL, and other standards, suitable for procurement as configuration components for export products
- Multiple Capacitance Specifications Comprehensively Covering Various Fan Power Requirements: Wide-range capacitance specifications from 1μF to above 20μF, accommodating motor configuration requirements from small-power decorative fans to large-power industrial axial flow fans

◆ Primary Applications
- Single-phase motor starting and running for household ceiling fans, desk fans, and floor fans
- Motor configuration for ventilation fans, bathroom heater fans, and kitchen range hood fans
- Cross-flow fan motors for air conditioner indoor units and axial flow fan motors for outdoor units
- Industrial ventilation equipment and commercial exhaust fans
- Starting assistance for single-phase AC motors in water pumps and power tools
