Gowanda’s SMRF1512S-224K is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/11 compliant component weighs 0.12 grams and measures 3.94 × 3.175 × 3.56 mm, making it suitable for surface mount technology (SMT). It features an inductance of 2200 µH, a direct current resistance (DCR) of 30 Ω, and a current rating of 0.04 A DC. The inductor operates at a self-resonant frequency (SRF) of 1.4 MHz and is tested at 0.25 MHz with a minimum Q factor of 75. It is designed to withstand dielectric withstanding voltages (DWV) of 200 and 500, with a tolerance of ±10%. The component is RoHS compliant with gold termination finish and a ferrite core, ensuring effective shielding. It operates within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging.
