Gowanda’s SMRF1210S-121G is a molded shielded inductor designed for high reliability in electronic applications. Weighing just 0.05 grams, it features compact dimensions of 3 × 2.16 × 2.06 mm and is part of the SMRF1210S series. This surface-mount technology (SMT) component is suitable for COTS+ grade applications, offering an inductance of 1.2 µH with a direct current resistance (DCR) of 0.49 Ω and a current rating of 0.574 A DC. It operates at a self-resonant frequency (SRF) of 120 MHz and is tested at 7.9 MHz with a minimum Q factor of 40. The inductor has a tolerance of ±2% and features lead-based (Pb) termination with a Sn63Pb37 finish. Constructed with a ferrite core, it is not shielded but is designed to operate in temperatures ranging from -55°C to +125°C. With a moisture sensitivity level (MSL) of 1, it is packaged in tape and reel (T&R) format and is fungal inert, ensuring durability and reliability in various environments.
