Line coupling transformers 74710

Power Line Communication Coupling Transformes

74710-(3)

 

 Designed for coupling signals to power line
Adapted for use with Modem Circuits: ST 7537 or TDA 5051 or IC/SS

 

Models 74710 and 74711 are designed for resonance at 132.5 kHz between the series coupling capacitor (33nF) and the  transformer leakage inductance.

Models 74712 and 74713 are designed for resonance at 132.5 kHz between the capacitor (6.8nF or 10nF) in parallel with the  primary magnetizing inductance.
