◆ Product Advantages
• Ultra-High Energy Density: Metallized polypropylene film dielectric provides far higher energy density than conventional capacitors of the same volume, enabling rapid release of large amounts of stored electrical energy to meet demanding instantaneous high-current requirements of pulse applications
• High Peak Current Capability: Non-inductive winding results in extremely low equivalent series inductance (ESL), allowing the capacitor to withstand peak discharge currents of thousands of amperes without damage
• Extended Charge-Discharge Cycle Life: Capable of sustaining hundreds of thousands to over one million charge-discharge cycles with minimal performance degradation, ideal for high-frequency pulse duty cycles
• Plastic Case Design: UL94-V0 flame-retardant plastic housing offers lightweight construction and excellent insulation; leads can be customized with insulating sleeves or different terminal configurations

◆ Key Selling Points
• Outstanding Self-Healing Property: In the event of localized breakdown, the metallized layer self-evaporates to clear the fault point and restore normal operation, significantly enhancing reliability and service life
• Wide Operating Temperature Range: Stable performance from -40°C to +85°C, suitable for demanding environmental conditions
• Customization Service: Capacitance, voltage, dimensions, and lead configurations can all be tailored to customer specifications
• International Certifications: Compliant with IEC, UL, and other international electrical safety standards

◆ Primary Applications
• External defibrillators and AED systems
• Industrial pulsed laser power supplies
• Electromagnetic launch systems and railgun energy storage
• High-frequency pulse welding equipment
• Medical and scientific high-voltage pulse energy storage devices
