Gowanda’s SMRF1512S-180K 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 0.18 µH with a direct current resistance (DCR) of 0.04 Ω and a current rating of 1 A DC. The inductor operates at a self-resonant frequency (SRF) of 460 MHz and is tested at 25 MHz with a minimum Q factor of 79. It supports a dielectric withstanding voltage (DWV) of 200 and 500, with a tolerance of ±10%. The termination is RoHS compliant with an Au finish, and the core is made of ferrite, ensuring effective shielding. It operates within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, packaged in tape and reel (T&R) format for ease of use in automated assembly processes.
