Gowanda’s SMRF1812-821K is a high-quality molded unshielded inductor designed for demanding applications, featuring a compact size with dimensions of 4.064 × 3 × 2.9 mm and a weight of 0.15 g. This COTS M83446/39 series inductor is suitable for surface mount technology (SMT) and is crafted for COTS+ application grade. It offers an inductance of 8.2 µH with a direct current resistance (DCR) of 1.4 Ω and a current rating of 0.375 A DC. The inductor operates efficiently with a self-resonant frequency (SRF) of 25 MHz and a test frequency of 7.9 MHz, maintaining a minimum Q factor of 50. It has a tolerance of ±10% and utilizes a ferrite core with a lead-based termination type, finished with Sn63Pb37. The component is designed to function in extreme temperatures ranging from -55°C to +125°C, with a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring reliability in various environments.
