Gowanda’s SMRF1512S-820KS is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. As part of the COTS M83446/11 series, it features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g. This surface-mount technology (SMT) component is suitable for COTS+ application grades, offering an inductance of 0.82 µH with a direct current resistance (DCR) of 0.06 Ω and a current rating of 0.7 A DC. It operates efficiently with a self-resonant frequency (SRF) of 185 MHz and a test frequency of 25 MHz, maintaining a minimum Q factor of 106. The inductor is built with a ferrite core and is shielded to minimize electromagnetic interference. It supports a wide operating temperature range from -55°C to +125°C and is compliant with moisture sensitivity level (MSL) 1 standards. The component is available with Pb and RoHS-compliant terminations, finished with Sn63Pb37 or SnCu, and is packaged in tape and reel (T&R) format for ease of handling and installation.
