Your Current ESR Capacitor Pain Points

High Purchase Price: Imported capacitors often carry 30‑40 % markup.
Unstable ESR Values: Wide tolerance leads to ripple‑current failures.
Long Lead Times: 6‑8 weeks from overseas suppliers disrupts production schedules.
Insufficient Technical Support: Generic datasheets lack application‑specific guidance.
Regulatory Uncertainty: Lack of CE, FCC, RoHS certifications blocks market entry.

Result: Downtime, warranty claims, and missed ROI targets.

Frequently Asked Questions

What is ESR and why does it matter for my power‑supply design?

ESR (Equivalent Series Resistance) represents the internal resistance of a capacitor. Lower ESR reduces heat, improves ripple‑current handling, and increases overall efficiency—critical for high‑current applications such as data‑center UPS, EV inverters, and medical equipment.

High Pass Filter Capacitor

Can you provide custom voltage or capacitance values?

Yes. Our R&D team (10 engineers) can design OEM/ODM capacitors from 10 µF up to 500 µF and voltages from 100 V to 600 V, with tolerance and packaging tailored to your BOM.

What certifications do your ESR capacitors hold?

All units are CE, FCC, RoHS, UL, ISO 9001, VDE, GS, and SAA certified. Test reports are available on request for compliance audits.

What are the payment terms for bulk orders?

Standard terms are T/T 30 % upfront, 70 % before shipment. For trusted partners we accept L/C at sight or net‑30 days after delivery.

How fast can you ship a 10 k piece order?

Our fully automated lines can produce 10 k pieces in 5 working days. Air freight from Shenzhen to Los Angeles takes 3‑4 days; door‑to‑door delivery is under 10 days total.
