CST4835-125E and CST4835-125EC are surface-mount current sense transformers designed to sense continuous currents up to 7 A at frequencies from 13 kHz to above 1 MHz, with a 1:125 turns ratio. The device features a 4.5 × 4.8 mm footprint, 500 Vrms one-minute isolation, and operates from -40°C to +125°C ambient temperature with a maximum part temperature of +165°C. It meets AEC-Q200 Grade 1 standards, is halogen-free and RoHS compliant, and includes tin over nickel over copper terminations. Inductance is 1280 µH measured at 100 kHz, 0.1 Vrms, and terminating resistance is 17.9 ohms for a 1 V output at 7 A primary current. Packaging is 500 per 7-inch reel or 2200 per 13-inch reel in EIA-481 embossed plastic tape.
