Gowanda’s SMRF1812T-392K 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) applications. It features a 39 µH inductance with a DCR of 7.4 Ω and a current rating of 0.155 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 12 MHz and a test frequency of 2.5 MHz, maintaining a minimum Q factor of 30. It offers a tolerance of ±10% and utilizes a powdered iron core. The component is designed for commercial off-the-shelf plus (COTS+) application grade and can withstand operating temperatures from -55°C to +125°C. It is packaged in tape and reel (T&R) format, is fungal inert, and has a moisture sensitivity level (MSL) of 1. The termination type is lead-based (Pb) with a Sn63Pb37 finish.
