Gowanda’s SMRF1812S-223K is a molded shielded inductor designed for high reliability in electronic applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this component is part of the SMRF1812S series and is suitable for surface mount technology (SMT). It features a COTS+ application grade with an inductance of 220 µH, a DCR of 7.5 Ω, and a current rating of 0.164 A DC. The inductor is capable of handling a saturation current of 0.07 A DC and has a self-resonant frequency (SRF) of 4.2 MHz. It is tested at a frequency of 0.79 MHz with a minimum Q factor of 40 and a tolerance of ±10%. The component uses a ferrite core and is shielded, with a termination type of Pb and a finish of Sn63Pb37. It operates within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R). Additionally, it is fungal inert, ensuring durability in various environments.
