Gowanda’s SMRF1512-121M is an unshielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/10 component weighs 0.12 grams and measures 3.94 × 3.175 × 3.56 mm, making it suitable for space-constrained environments. It features a surface-mount technology (SMT) mounting type and is part of the SMRF1512 series, with an application grade of COTS+. The inductor offers an inductance of 1.2 µH, a direct current resistance (DCR) of 0.45 Ω, and a current rating of 0.33 A DC. It operates at a self-resonant frequency (SRF) of 120 MHz and is tested at a frequency of 7.9 MHz, with a minimum Q factor of 65 and a tolerance of ±20%. The component is RoHS compliant with gold termination finish and uses a powdered iron core. It is designed to operate 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.
