Gowanda’s SMRF1512S-122M 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 space-constrained environments. It features a surface-mount technology (SMT) mounting type and is part of the SMRF1512S series. With an inductance of 12 µH, a direct current resistance (DCR) of 1.5 Ω, and a current rating of 0.18 A DC, it is optimized for performance with a self-resonant frequency (SRF) of 34 MHz and a test frequency of 2.5 MHz. The inductor offers a minimum quality factor (Q MIN) of 100 and dielectric withstanding voltage (DWV) options of 200 and 500. It has a tolerance of ±20% and is RoHS compliant with gold termination finish. The ferrite core and shielded design ensure stability across a wide operating temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging.
