FAQ

Q: What does end frequency amplitude roll-off ≤30% mean?

A: At the low-frequency end of 40Hz and the high-frequency end of 10kHz, signal amplitude attenuation does not exceed 30%, ensuring good signal transmission quality is maintained even at the frequency range boundaries.

Q: What does insertion loss of 2.0dB @1kHz represent?

A: At the 1kHz reference frequency, the power loss of the signal passing through the transformer is 2.0dB. Lower insertion loss means higher signal transmission efficiency.

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.
