The CST7030 series comprises surface mount current sense transformers designed for AC current monitoring up to 20 A and frequencies above 1 MHz, with 500 Vrms isolation between windings. The CST7030-150L variant features a 1:150 turns ratio, 2.993 mH secondary inductance, and a terminating resistance of 7.5 ohms to produce 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 meets AEC-Q200 qualifications for automotive applications. The part is packaged in 7" or 13" tape reels, uses RoHS-compliant tin-silver-copper terminations, and has a physical footprint of 4.85 mm by 7.0 mm. It is suitable for switched-mode power supplies, traction systems, battery management in xEVs, and 48 V vehicle electrical systems.
