Gowanda’s SMRF1512-101KS is an unshielded epoxy-coated chip inductor designed for high reliability in demanding applications. As part of the COTS M83446/10 series, this component features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g. It is suitable for surface mount technology (SMT) and is graded for COTS+ applications. The inductor offers an inductance of 1 µH, a direct current resistance (DCR) of 0.34 Ω, and a current rating of 0.38 A DC. It operates with a self-resonant frequency (SRF) of 130 MHz and is tested at a frequency of 25 MHz, with a minimum quality factor (Q) of 75 and a tolerance of ±10%. The component uses a powdered iron core and is terminated with Pb, RoHS compliant finishes of Sn63Pb37 and SnCu. It is designed to operate within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging.
