FAQ

Q: What does open-circuit inductance of 350µH Min mean?

A: Open-circuit inductance (OCL) is an important parameter for Ethernet transformers. The 350µH minimum ensures signal transmission integrity and common-mode rejection capability under typical operating conditions, meeting the performance requirements of 10/100Base-TX networks.

Q: How to choose between SMD and THT packages?

A: SMD (surface mount) is suitable for automated SMT production lines, ideal for high-volume production. THT (through-hole) is suitable for wave soldering, allowing easy manual soldering and prototyping. Please choose based on your production process.

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

A: You can submit a sample application through our website or email. Please provide your company information and target model. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks.
