PCB Mount Pulse Transformer

What is PCB Transformer

Key Features

Engineered for broadband PLC systems, this PCB-mount pulse transformer delivers precision signal isolation with a 1:1:1 turns ratio. Featuring ultra-low leakage inductance (25μH max) and minimal rise time (1.5μs), it ensures high-speed data integrity. Shielded construction minimizes EMI interference, while RoHS-compliant materials support sustainable designs. Optimized for synergy with EMC Filters and RF Inductors in noise-critical circuits.
