Frequently Asked Questions
What is the difference between CD135 and CD139 series?
CD135 series uses snap-in mounting suitable for PCB assembly and automated production, while CD139 series uses screw terminals for chassis mounting. CD135 is more compact and cost-effective for medium power applications (15-30kW), while CD139 offers higher ripple current and easier field maintenance for high-power applications (30-75kW). Both series offer similar voltage ratings and lifespan characteristics.
Choose CD135 for PCB-mounted applications and cost-sensitive designs. Choose CD139 for chassis mounting and high-ripple current requirements.
What are the PCB layout recommendations for CD135 snap-in capacitors?
CD135 snap-in capacitors require proper PCB layout for optimal performance and lifespan. Recommended practices: 1) Keep capacitor away from heat-generating components (IGBTs, inductors); 2) Maintain minimum 10mm spacing between capacitors for airflow; 3) Use adequate copper area for heat dissipation; 4) Ensure proper hole size (6.5mm diameter for standard snap-in); 5) Consider vibration resistance in high-vibration environments.
