Gowanda’s SMRF1210-221M is a molded unshielded 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 SMRF1210 series. This surface-mount technology (SMT) component is suitable for COTS+ application grades, offering an inductance of 2.2 µH with a direct current resistance (DCR) of 1 Ω and a current rating of 0.431 A DC. It operates at a self-resonant frequency (SRF) of 70 MHz, with a test frequency of 7.9 MHz and a minimum Q factor of 30. The inductor has a tolerance of ±20% and features Pb termination with a Sn63Pb37 finish. Constructed with a ferrite core, it is not shielded but is fungal inert and can operate in temperatures ranging from -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1 and is available in tape and reel (T&R) packaging.
