FAQ
Q: How to apply for samples? What is the lead time?
A: You can submit a sample application through our website or email. 3-5 free samples are provided 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: What are the inductance range and package types of the SPT series transformer?
A: This series offers three package types: SPT-01, SPT-02, and SPT-03. Inductance range is 3.5µH to 70µH, with inductance tolerance of ±20%. Leakage inductance is typically 0.06µH to 0.11µH, and maximum DCR is 0.05Ω to 0.07Ω. Test conditions are @25°C.
