1. Low sensitivity, high flow resistance, strong adaptability to working conditions:Low inductance structure design, able to efficiently adapt to the high-frequency working rhythm of equipment, while carrying large ripple current, withstanding instantaneous current impact, and easily cope with the complex power consumption conditions of power electronic equipment
2. Low consumption and high efficiency, stable voltage and ripple suppression:High quality polypropylene film medium, low electrical loss, can quickly absorb circuit ripple current, effectively suppress voltage fluctuations, stabilize circuit output, and protect core power devices inside the equipment
3. High temperature resistance and aging resistance, long life and maintenance free:All components are made of industrial grade temperature resistant materials, which are resistant to high temperature and aging, without problems such as medium cracking and electrode falling off, and can still work stably for a long time under high temperature conditions inside the equipment, reducing maintenance costs
4. Explosion proof and flame retardant, with adequate safety protection in place:Built in explosion-proof pressure relief structure, combined with UL94 V-0 flame retardant packaging, eliminates the risk of explosion and fire caused by capacitor overvoltage and overcurrent from the source, making it safer and more reliable to use
5. Multi specification and easy installation, suitable for a wide range of scenarios:Covering multiple voltage and capacity specifications, supporting various installation methods such as direct insertion and bolt fixation, with standardized dimensions that can directly match the installation layout of various power electronic devices, making replacement and assembly convenient
6. All solid structure, strong environmental adaptability:No liquid, no leakage hazard, non-polar design suitable for AC/DC circuits, and also has moisture-proof, anti vibration, and anti slight chemical corrosion characteristics, suitable for different indoor and outdoor use environments of equipment
