FAQ

Q: What are the advantages of epoxy potting?

A: Epoxy potting provides excellent moisture-proof, dust-proof, and insulation protection, ensuring long-term stable operation of the transformer in various harsh environments, enhancing mechanical strength and vibration resistance.

Q: What does a DCR value of 115Ω ±15% mean?

A: DCR (DC resistance) of 115Ω ±15% indicates the resistance value of the primary and secondary windings under DC conditions. This parameter affects the transformer's power loss and signal transmission efficiency.

Q: What data rates does this product support?

A: It supports data rates from 2400bps to 56.6Kbps (V.90), suitable for communication applications such as modems and PCMCIA.

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.
