Pulse transformers transfer high-speed digital pulses while providing galvanic isolation — used for isolated gate driving of MOSFETs and IGBTs in power converters, coupling Ethernet data pulses, and isolating signals in industrial CAN and RS-485 communication interfaces. Our pulse transformer inventory covers gate-drive transformers (1:1, 1:2, 2:1 turns ratios), Ethernet pulse transformers (for 10/100BASE-TX), and general-purpose pulse transformers from Würth Elektronik (WE-PPT series), Pulse Electronics, TDK (PE-xxxx series), Coilcraft (POxxx series), and Bourns — with isolation voltages from 500Vrms to 5kVrms, bandwidth from 1kHz to 100MHz, and SMD or through-hole packages.
High-isolation (5kVrms+) pulse transformers for medical equipment (IEC 60601-1) and automotive gate-drive transformers (AEC-Q200) are frequently on long lead times. Welllinkchips stocks standard pulse transformer configurations and can source discontinued or custom-turns-ratio transformers for legacy industrial equipment and power supply repair.
