Gowanda’s SMRF1512S-681MS is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/11 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 6.8 µH, a DCR of 0.66 Ω, and a current rating of 0.27 A DC. The inductor operates at a self-resonant frequency (SRF) of 45 MHz and a test frequency of 7.9 MHz, with a minimum Q factor of 115. It is designed to withstand dielectric withstanding voltages (DWV) of 200 and 500, with a tolerance of ±20%. The termination type is Pb, RoHS compliant, with a finish of Sn63Pb37 or SnCu. The core is made of ferrite, and the component is shielded, operating within a temperature range of -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1 and is available in tape and reel (T&R) packaging.
