Application-Specific FAQ
Q: Can I use this capacitor in a 380 V AC three-phase VFD?
A: Yes. A 380 V AC input rectifies to approximately 537 V DC peak; however, with a 400 V rated capacitor, you must ensure the DC bus voltage stays within the capacitor’s rated voltage under all operating conditions. For 380 V AC systems, a 450 V or 500 V rated capacitor is typically recommended for adequate derating margin. Consult your drive’s DC bus voltage specification before substituting.
Q: What is the expected service life in a 60°C ambient environment?
A: Using the Arrhenius rule-of-thumb (life halves for every 10°C rise), an 85°C-rated capacitor operating at 60°C with 80% voltage derating can achieve 8,000–16,000+ hours of service life depending on ripple current loading.
Q: Is this a snap-in or screw-terminal type?
A: The POSITIVE series in this capacitance/voltage range is typically available in both snap-in and screw-terminal configurations. Please confirm your PCB or bus bar mounting requirement when ordering so we can supply the correct termination style.
Q: Can multiple units be connected in parallel to increase capacitance?
A: Yes. Parallel connection is standard practice for increasing total capacitance and ripple current handling. Ensure matched ESR values and symmetric bus bar layout to prevent unequal current sharing.
Q: Do you provide a datasheet?
A: Yes. Official NIPPON CHEMI-CON datasheets are available upon request. Contact support@konmask.com with your part number.
