Gowanda’s SMRF1812S-272M is a molded shielded inductor designed for high reliability in electronic applications. Weighing just 0.15 grams, it features compact dimensions of 4.2 × 3 × 2.9 mm and is part of the SMRF1812S series. This surface-mount technology (SMT) component is suitable for COTS+ application grades, offering an inductance of 27 µH with a direct current resistance (DCR) of 1.56 Ω. It supports a current rating of 0.358 A DC and a saturation current of 0.207 A DC, with a self-resonant frequency (SRF) of 13 MHz. Tested at a frequency of 2.5 MHz, it boasts a minimum Q factor of 50 and a tolerance of ±20%. The inductor is constructed with a ferrite core and features lead (Pb) termination with a Sn63Pb37 finish. It is shielded and operates within a temperature range of -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, ensuring durability and performance in demanding environments.
