Gowanda’s SMRF1512S-120K is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This component, part of the SMRF1512S series, is a COTS M83446/11 grade product, ensuring it meets stringent commercial off-the-shelf standards. With dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g, it is compact yet robust. It features a 0.12 µH inductance, a DCR of 0.03 Ω, and a current rating of 1 A DC. The inductor operates efficiently with a self-resonant frequency of 520 MHz and a test frequency of 25 MHz, boasting a minimum Q factor of 79. It is designed for surface mount technology (SMT) with RoHS-compliant gold termination, and its ferrite core is shielded to minimize electromagnetic interference. The device can withstand a dielectric withstanding voltage (DWV) of 200 to 500 and operates within a temperature range of -55°C to +125°C, making it suitable for various environmental conditions. It is packaged in tape and reel (T&R) format and has a moisture sensitivity level (MSL) of 1, indicating high reliability and ease of handling.
