Durable Capacitor

Durable Capacitor

Frequent charge and discharge impacts and high electrical stress are the main causes of capacitor failure. We launched our Durable Capacitor specifically to address these issues. This product has systematic reinforcement in impact resistance. It can withstand high-frequency voltage fluctuations and current surges without performance degradation. The core dielectric uses enhanced polypropylene film with excellent corona resistance and aging resistance. The electrode system is treated against electrochemical corrosion. It maintains stable conductive performance even in humid or slightly polluted environments. Our product is especially suitable for motor starting capacitors, high-power pulse power supply storage capacitors, and frequently switched reactive power compensation devices. It demonstrates durability far beyond ordinary products under rigorous charge-discharge cycles.

Robust Mechanical Design

 

In structural design, our Durable Capacitor fully considers mechanical vibration and thermal expansion effects in real applications. The housing uses high-strength heat-resistant materials. The internal components use flexible support structures. This effectively buffers thermal and mechanical stress on internal connection points. The potting material uses high-thermal-conductivity, high-adhesion environmentally friendly resin. This ensures good heat dissipation and long-term positioning stability of internal components. Our product has passed accelerated life tests and long-term simulated field condition tests. Its excellent durability has been fully verified by many industrial customers worldwide.
