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: What are the operating frequency and output power ranges of the EE/EF series?
A: The operating frequency range is 30 to 500KHz. The output power range is 0.5 to 10W, and can reach 3 to 650W depending on configuration. The wide frequency and power range makes it suitable for various switching power supply and high-frequency circuit applications.
Q: Why is this product suitable for applications with lower EMI shielding requirements?
A: This product uses a low-cost design, primarily suitable for applications with lower EMI shielding requirements. The ferrite core combined with optimised winding processes reduces production costs while meeting basic performance requirements, making it suitable for cost-sensitive consumer electronics and power supply applications.
