SMRF1812T-331M

Gowanda’s SMRF1812T-331M is a molded unshielded temperature stable 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 SMRF1812T series and is suitable for surface mount technology (SMT). It features an inductance of 3.3 µH, a DCR of 0.83 Ω, and a current rating of 0.492 A DC. With a self-resonant frequency (SRF) of 46 MHz and a test frequency of 7.9 MHz, it offers a minimum Q factor of 28 and a tolerance of ±20%. The inductor is constructed with a powdered iron core and has a termination type of Pb with a Sn63Pb37 finish. It operates effectively in temperatures ranging from -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, making it suitable for COTS+ application grades.
