The CST3015-050ED from Coilcraft is an Automotive-Qualified Current Sense Transformer. This transformer requires a primary current of 80 A. It has an inductance of 0.8 mH and an inductance tolerance of 25%. This AEC-Q200 Grade 1-qualified transformer has a turns ratio of 1:5. It includes a ferrite core material and has very low primary DC resistance to control the core loss, which makes it ideal for designs operating up to 1 MHz and beyond. This RoHS-compliant transformer also meets reinforced insulation requirements of at least 8 mm and provides an isolation voltage of 5000 V for 1 minute across its windings. It is available in a surface-mount package that measures 1.181 x 0.906 x 0.598 mm.
