SRN5040TA-1R0M is a semi-shielded power inductor from Bourns designed for use in DC/DC converters and power supply applications. The device features a 1.0 µH inductance with ±20% tolerance, a DC resistance of 0.012 O, and a rated RMS current of 5.0 A with a saturation current of 7.50 A. It operates across a temperature range of -55°C to +125°C with a 40°C temperature rise at rated current, and exhibits a self-resonant frequency of 140 MHz with a quality factor of 15 at 100 kHz. The inductor is constructed with a ferrite core, enameled copper wire, and magnetic epoxy resin coating, offering AEC-Q200 compliance, RoHS compliance, and halogen-free construction. These specifications make it well-suited for compact power conversion circuits requiring reliable inductance with minimal DC losses.
