Gowanda’s SMRF1512S-220M is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/11 compliant component features a compact design with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g, making it suitable for surface mount technology (SMT). With an inductance of 0.22 µH, a DCR of 0.04 Ω, and a current rating of 1 A DC, it is optimized for performance with a self-resonant frequency (SRF) of 430 MHz and a minimum Q factor of 79 at a test frequency of 25 MHz. The inductor is constructed with a ferrite core and gold termination finish, ensuring RoHS compliance. It operates reliably across a wide temperature range from -55°C to +125°C and is rated at moisture sensitivity level (MSL) 1, packaged in tape and reel (T&R) for efficient handling.
