Gowanda’s SMRF1512S-220MS is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This component, part of the SMRF1512S series, is a COTS M83446/11 grade product, ensuring it meets stringent commercial off-the-shelf standards. With dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g, it is compact and suitable for surface mount technology (SMT). It features an inductance of 0.22 µH, a direct current resistance (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, boasting a minimum quality factor (Q MIN) of 79. It is designed to withstand dielectric withstanding voltages (DWV) of 200 and 500, with a tolerance of ±20%. The component is RoHS compliant, with termination finishes of Sn63Pb37 and SnCu, and is constructed with a ferrite core for enhanced performance. It operates within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various environmental conditions. The SMRF1512S-220MS is packaged in tape and reel (T&R) for efficient handling and installation.
