Frequently Asked Questions

What are the typical applications for Capxon snap-in capacitors?

Snap-in capacitors are used in industrial power supplies, inverters, motor drives, UPS systems, and welding equipment. They are ideal for high-power applications requiring large capacitance values and high ripple current capability.

For power supplies above 100W, snap-in capacitors provide better thermal performance and reliability.

What is the difference between SF, SM, and SH series?

SF series is the standard snap-in capacitor for general applications. SM series features low impedance for high-frequency switching power supplies. SH series offers higher temperature ratings up to 105°C and longer lifetime for demanding environments.

Use SF series for standard applications. Use SM series for high-frequency power supplies. Use SH series for high-temperature applications.

What is the typical lifetime of Capxon snap-in capacitors?

Standard snap-in capacitors are rated for 2,000 to 5,000 hours at 85°C or 105°C. High-temperature SH series offers up to 10,000 hours at 105°C. Lifetime can be extended significantly with proper derating.

For extended lifetime, operate at lower temperatures and use voltage derating.

What mounting options are available for snap-in capacitors?

Snap-in capacitors feature PCB mounting terminals that snap into holes on the PCB. Standard spacing is 5mm or 7.5mm depending on case size. Some series also offer threaded terminals for additional security.

Ensure PCB hole spacing matches the capacitor terminal spacing for proper mounting.

What is the ripple current capability of Capxon snap-in capacitors?

Ripple current ratings range from 2A to 20A depending on capacitance, voltage, and case size. SM low-impedance series offers the highest ripple current capability for demanding applications. When designing for ripple current, it is important to consider both the RMS value and the frequency spectrum. Higher frequencies may result in increased heating due to frequency-dependent ESR characteristics. Proper PCB layout with adequate copper area can help dissipate heat generated by ripple current.

Select capacitors with ripple current ratings at least 1.5x your application requirements for reliable operation.

Can snap-in capacitors be used in parallel for higher capacitance?

Yes, multiple snap-in capacitors can be connected in parallel to increase total capacitance and share ripple current. This is common in high-power applications. Ensure balanced current sharing through symmetrical layout.

For very high capacitance requirements, consider parallel connection of multiple snap-in capacitors.
