Coilcraft, Inc. CST2010 Series SMT Current Sense Transformers CST2010-080L CST2010-080LD

CST2010-080L and CST2010-080LD are surface mount current sense transformers designed for sensing currents up to 47 A at frequencies up to 1 MHz and above, with a turns ratio of 1:80 and a secondary inductance of 5.44 mH. They feature less than 0.560 ohms secondary DC resistance, 1500 Vrms isolation between windings, and operate across an ambient temperature range of -40°C to +125°C, meeting AEC-Q200 Grade 1 requirements. The part is packaged in a 32 mm wide tape on a 13-inch reel with 20 mm pocket spacing, weighs 4.13 g, and supports three reflows at 260°C. Its dimensions are 13.0 mm x 16.51 mm with a maximum height of 19.91 mm, and it has a 12-pin layout. Terminating resistance is 2.0 ohms for a 1 V output at 40 A primary current.
