Gowanda’s SMRF1512-470KS is an unshielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/10 component weighs 0.12 grams and measures 3.94 × 3.175 × 3.56 mm, making it suitable for surface mount technology (SMT). It features an inductance of 0.47 µH with a direct current resistance (DCR) of 0.14 Ω and a current rating of 0.59 A DC. The inductor operates at a self-resonant frequency (SRF) of 190 MHz and is tested at 25 MHz with a minimum Q factor of 70. It offers a tolerance of ±10% and is terminated with Pb, RoHS compliant finishes of Sn63Pb37 and SnCu. Constructed with a powdered iron core, it operates effectively within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), it is ideal for commercial off-the-shelf (COTS+) applications.
