Gowanda’s SMRF1512S-220KS is a shielded epoxy-coated chip inductor designed for high reliability in electronic applications. This component, part of the SMRF1512S series, features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g, making it suitable for surface mount technology (SMT). It is built to meet COTS+ application grade standards, offering an inductance of 0.22 µH with a DCR of 0.04 Ω and a current rating of 1 A DC. The inductor operates efficiently with a self-resonant frequency (SRF) of 430 MHz and a test frequency of 25 MHz, ensuring a Q MIN of 79. It is designed to withstand a dielectric withstanding voltage (DWV) of 200, 500, and operates within a temperature range of -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 performance. Packaged in tape and reel (T&R) format, it is ideal for automated assembly processes.
