Gowanda’s SMRF1512-820MS is an unshielded epoxy-coated chip inductor designed for high reliability in demanding applications. This component is part of the COTS M83446/10 series, featuring 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 classified under the COTS+ application grade. The inductor offers an inductance of 0.82 µH, a direct current resistance (DCR) of 0.3 Ω, and a current rating of 0.4 A DC. It operates at a self-resonant frequency (SRF) of 150 MHz, with a test frequency of 25 MHz and a minimum Q factor of 75. The product has a tolerance of ±20% and uses Pb, RoHS compliant terminations with a Sn63Pb37, SnCu finish. Constructed with a powdered iron core, it is designed to function in temperatures ranging from -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The SMRF1512-820MS is available in tape and reel (T&R) packaging, making it ideal for automated assembly processes.
