FAQ

Q: How to apply for samples? What is the lead time?

A: You can submit a sample application through our website or email. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks; custom products will be confirmed separately.

Q: Do you support small trial orders?

A: Yes. Small trial orders (below the standard MOQ) can be negotiated and receive the same quality standards and delivery commitments as mass orders. Please contact our sales team for details.

Q: Do you provide technical support and selection recommendations?

A: Yes. We have a professional technical team that can provide selection recommendations and customisation solutions based on customer application scenarios and circuit requirements.

Q: Does this product support customisation?

A: Yes. Inductance, impedance, DCR, and current rating can be customised based on customer circuit diagrams or application requirements. Please contact our sales team to confirm the customisation plan.
