Gowanda’s SMRF1512S-390MS is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This component is part of the SMRF1512S series and features 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, ensuring it meets commercial off-the-shelf standards with enhanced performance. The inductor offers an inductance of 0.39 µH, a low DC resistance of 0.05 Ω, and a current rating of 0.75 A DC. It operates efficiently across a frequency range, with a self-resonant frequency (SRF) of 280 MHz and a test frequency of 25 MHz. The component is built with a ferrite core and is shielded to minimize electromagnetic interference. It is designed to withstand harsh environments, with an operating temperature range from -55°C to +125°C and a moisture sensitivity level (MSL) of 1. The SMRF1512S-390MS is terminated with Pb and RoHS-compliant finishes, available in Sn63Pb37 and SnCu, and is packaged in tape and reel (T&R) for ease of handling and installation.
