Product Overview
KV Electronics Telecom Transformers (Signal/Pulse Transformers) are precision-engineered for data communication interfaces, Power over Ethernet (PoE), ADSL/VDSL, and telecom line coupling applications. Built on small-footprint RM, EE, or pot-core ferrite cores, these transformers provide excellent impedance matching, galvanic isolation, and common-mode noise rejection across a wide frequency band.
Available in SMD and through-hole packages compatible with standard PCB footprints (Ethernet magnetics, Halo-compatible, etc.). Custom inductance values, turns ratios, and pin-out configurations are available for OEM requirements.
