Datasheet
Datasheet Summary
Powered by GS/AI

The CST7030 series consists of surface mount current sense transformers designed for AC current monitoring up to 20 A and frequencies up to 1 MHz, with 500 Vrms isolation between windings and AEC-Q200 qualification for automotive use. The CST7030-070L variant has a 1:70 turns ratio, 0.652 mH secondary inductance at 100 kHz, and a 3.5 Ω terminating resistance for a 1 V output at 20 A primary current. It operates from -40°C to +125°C ambient, with a maximum part temperature of +165°C, and is packaged in 7" or 13" reels with EIA-481 embossed plastic tape. The device meets moisture sensitivity level 1 and has RoHS-compliant tin-silver-copper terminations.
