Gowanda’s SMRF1812S-271J is a molded shielded inductor designed for high reliability and performance in electronic applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812S series and is suitable for surface mount technology (SMT). It is classified as COTS+ grade, ensuring it meets commercial off-the-shelf standards with enhanced reliability. The inductor offers an inductance of 2.7 µH, a direct current resistance (DCR) of 0.237 Ω, and a current rating of 0.918 A DC, with a saturation current of 0.761 A DC. It operates at a self-resonant frequency (SRF) of 50 MHz and is tested at a frequency of 7.9 MHz, with a minimum quality factor (Q) of 40. The component features a tolerance of ±5%, lead (Pb) termination type with a Sn63Pb37 finish, and a ferrite core. It is shielded and can operate in temperatures ranging from -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), it is also fungal inert, making it suitable for various demanding environments.
