Gowanda’s SMRF1512S-821KS is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/11 compliant component features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and weighs just 0.12 g. It is suitable for surface mount technology (SMT) and operates within an inductance of 8.2 µH, a DCR of 1 Ω, and a current rating of 0.225 A DC. The inductor offers a self-resonant frequency (SRF) of 41 MHz and a test frequency of 7.9 MHz, with a minimum Q factor of 115. It is designed to withstand a dielectric withstanding voltage (DWV) of 200, 500 and maintains performance across a wide operating temperature range from -55°C to +125°C. The component is RoHS compliant, with termination finishes available in Sn63Pb37 and SnCu, and features a ferrite core for enhanced shielding. It is packaged in tape and reel (T&R) format, ensuring ease of handling and integration into electronic assemblies.
