Gowanda’s SMRF1512S-821M 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 commercial off-the-shelf standards with enhanced performance. It 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). The inductor offers an inductance of 8.2 µH, a direct current resistance (DCR) of 1 Ω, and a current rating of 0.225 A DC. It operates efficiently with a self-resonant frequency (SRF) of 41 MHz and a test frequency of 7.9 MHz, providing a minimum quality factor (Q MIN) of 115. The device is designed to withstand dielectric withstanding voltages (DWV) of 200 and 500, with a tolerance of ±20%. It features RoHS-compliant gold termination and a ferrite core, ensuring durability and reliability. The inductor is shielded and operates within a 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 for easy handling and installation.
