Quad Port SMD 10/100Base-T Isolation Transformer Modules

Applications

Talema 10/100BaseT Quad transformer modules contain transmit and receive isolation transformers to maintain consistant

wave shape and suppression of common mode noise while providing equipment isolation per IEEE 802.3. High impedance

common mode quad chokes for additional EMI suppression have been added on some models as required for FCC and

CISPR 22 Class B certification.

Quality and consistency is guaranteed through 100% testing of the specified parameters for primary inductance, leakage

inductance, turns ratio, DC resistance and interwinding capacitance.This ensures that the return loss and pulse wave shape

requirements can be fully maintained. Additionally, all parts are tested for 1500V minimum isolation.
