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.
Applications
Talema 10/100Base-T transformer modules contain transmit and receive isolation transformers to maintain consistent 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.
