The CST7030 series consists of surface mount current sense transformers designed for sensing AC currents up to 20 A at frequencies up to 1 MHz and above, with 500 Vrms isolation between windings. The CST7030-050L variant has a 1:50 turns ratio, 0.333 mH secondary inductance, and a 2.5 ohm terminating resistance for a 1 V output at 20 A primary current. It features a maximum primary DCR of 0.333 ohms, operates from -40°C to +125°C ambient, and meets AEC-Q200 qualification with a maximum part temperature of +165°C. The device is packaged in 7" or 13" reels, with RoHS-compliant tin-silver-copper terminations and MSL 1 moisture sensitivity. It is intended for use in switched-mode power supplies, overcurrent protection, and electric vehicle battery and traction systems, including 48 V automotive networks.
