Frequently Asked Questions

What makes Capxon capacitors suitable for industrial power supplies?

Capxon capacitors for industrial applications feature high ripple current capability, extended temperature ratings, and robust construction. The snap-in series offers up to 20A ripple current capability and 10,000-hour lifetime ratings. These characteristics make them ideal for the demanding conditions found in industrial power supplies.

For industrial power supplies, select Capxon snap-in capacitors with appropriate ripple current and temperature ratings for your application.

How do I calculate the required capacitance for my power supply?

Required capacitance depends on several factors: output voltage, load current, allowable ripple voltage, and switching frequency. For DC bus applications, calculate based on energy storage requirements for hold-up time. For output filtering, calculate based on ripple current and allowable output voltage ripple. Our FAE team can provide detailed calculations for your specific application.

Contact our FAE team with your power supply specifications for detailed capacitance calculations and recommendations.

What is the recommended voltage derating for industrial applications?

For industrial applications, we recommend minimum 20% voltage derating (operate at 80% of rated voltage). For critical applications or high-temperature environments, 50% derating provides even better reliability. This derating provides margin for voltage transients and line regulation variations common in industrial power systems.

Use 20% derating as minimum, 50% derating for maximum reliability in critical applications.

How should I arrange capacitors for high ripple current applications?

For high ripple current, parallel connection of multiple capacitors is recommended. This reduces total ESR, distributes thermal load, and improves reliability. Use identical part numbers for balanced current sharing. Maintain symmetrical PCB layout with equal trace lengths. Ensure adequate spacing for thermal management.

For ripple current above 5A, consider parallel connection of multiple capacitors rather than a single large capacitor.

What thermal management is required for industrial capacitors?

Proper thermal management includes: adequate airflow through the enclosure, heatsinking if needed, proper spacing between capacitors for air circulation, and avoiding placement near heat-generating components. Measure actual operating temperature in the final enclosure under full load conditions.

Design for maximum 75°C capacitor temperature. Use thermal imaging to verify and improve thermal design.

What lifetime can I expect from Capxon industrial capacitors?

With proper derating and thermal management, Capxon industrial capacitors can achieve 10+ year operational life. Standard series rated for 2000 hours at 85°C can achieve 50,000+ hours at 50°C operating temperature. High-temperature series (105°C rated) provide even longer life.

For 10+ year life, use high-temperature series with proper derating and thermal management.
