Gowanda’s SMRF1210S-222K is a molded shielded inductor designed for high reliability in electronic applications. Weighing just 0.05 grams and measuring 3 × 2.16 × 2.06 mm, this component is part of the SMRF1210S series and is suitable for surface mount technology (SMT). It is classified as COTS+ grade, offering an inductance of 22 µH with a direct current resistance (DCR) of 3 Ω and a current rating of 0.232 A DC. The inductor operates within a frequency range of 2.5 MHz, with a self-resonant frequency (SRF) of 19 MHz and a minimum Q factor of 40. It features a tolerance of ±10% and uses a lead (Pb) termination type with a Sn63Pb37 finish. The core is made of ferrite, and it is not shielded. The operating temperature range is from -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is also fungal inert, making it suitable for various demanding environments.
