Pulse Transformers

Pulse Transformers are designed to transfer pulses (signals/voltage with a rapid rise time, a duration of constant signal/voltage, and then a rapid fall time) from one side of a circuit to another. The transformer types are ADSL, data/voice coupling, economical open type, gate drive, general purpose, HDBase-T, HDSL, interface, isolation and data interface, LAN, MIL-STD-1553, PoE, SCR and Triac Trigger, SHDSL, T1/E1, T3/E3, and VDSL.
