Why Your Current Buck Converter Parts Are Holding You Back

Excessive BOM cost: Typical suppliers charge 20‑40% above market average for comparable inductors.
Unreliable performance: 12% of field failures are traced to poor inductance tolerance and ESR drift.
Long lead times: 6‑8 weeks from order to delivery slows product launches.
Regulatory risk: Missing CE/UL certifications can delay customs clearance in the US and EU.
Limited customization: Off‑the‑shelf parts rarely match the exact ripple current or footprint required by high‑density buck converters.

Frequently Asked Questions

What is the typical lead time for a custom buck converter inductor?

Prototype samples are usually ready within 10‑14 days after receiving the design file and material approval. Full‑scale production starts within 4 weeks.

Can you meet UL and CE certification for both inductors and capacitors?

Yes. All our magnetic components are tested in‑house and third‑party labs to comply with UL 1449, IEC 60384, CE, and RoHS requirements.

Do you offer volume discounts for orders above 10 k pieces?

A tiered discount structure starts at 5 %** for 10‑25 k units and can reach up to **15 %** for orders exceeding 100 k pieces.

What payment terms are accepted for first‑time buyers?

We accept T/T 30 % deposit + 70 % before shipment, L/C at sight, or PayPal for samples. Credit terms (Net 30) are available after a successful trial order.

How do you handle after‑sales support and warranty?

All products carry a 24‑month warranty against material defects. Our technical support team is reachable 24 h/7 d via email, phone, or WhatsApp.
