Gowanda’s SMRF1512S-181M 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 1.8 µH, a DCR of 0.2 Ω, and a current rating of 0.5 A DC. With a self-resonant frequency (SRF) of 120 MHz and a test frequency of 7.9 MHz, it ensures optimal performance. The inductor has a Q MIN of 100 and a dielectric withstanding voltage (DWV) of 200, 500, with a tolerance of ±20%. It is RoHS compliant with an Au termination finish and a ferrite core, operating efficiently in temperatures ranging from -55°C to +125°C. The product is packaged in tape and reel (T&R) format and has a moisture sensitivity level (MSL) of 1, making it ideal for commercial off-the-shelf (COTS+) applications.
