Coilcraft, Inc. CST2010 Series SMT Current Sense Transformers CST2010-150L CST2010-150LD

The CST2010 series consists of surface mount current sense transformers designed for sensing currents up to 47 A at frequencies up to 1 MHz and above, with AEC-Q200 Grade 1 qualification for operation from -40°C to +125°C. The parts have a ferrite core, provide 1500 Vrms isolation between windings, and feature very low primary DC resistance. Each variant has a turns ratio from 1:20 to 1:200, with the CST2010-150L model specifying a 1:150 ratio, 19.2 mH secondary inductance, and a terminating resistance of 3.8 ohms for 1 V output at 40 A primary current. The package measures 13.0 mm by 16.51 mm and is supplied on 300-piece 13-inch reels with embossed plastic tape. The maximum part temperature is +165°C, with MSL 1 moisture sensitivity and resistance to three reflow cycles at 260°C.
