Datasheet
Datasheet Summary
Powered by GS/AI

CST2-125L and CST2-125LC are surface mount current sense transformers for sensing up to 20 A primary current at frequencies above 1 MHz, with a 1:125 turns ratio and 3000 µH secondary inductance. The devices feature 500 Vrms isolation, operate from -40°C to +125°C ambient, and meet AEC-Q200 Grade 1 requirements. They have a ferrite core, RoHS-compliant tin-silver over tin over nickel over phosphor bronze terminations on pins 1-6, and matte tin over nickel over copper on pins 7-8. The package weighs 0.4 g and supports reflow soldering per MSL 1. Tape and reel packaging is available in 7″ and 13″ formats.
