Gowanda’s SMRF1812T-331J is a high-quality, reliable molded unshielded temperature stable inductor, designed for demanding applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812T series and is suitable for surface mount technology (SMT) applications. It features an inductance of 3.3 µH, a direct current resistance (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 quality factor (Q MIN) of 28 and a tolerance of ±5%. The inductor uses 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 and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is also fungal inert, making it suitable for a variety of commercial off-the-shelf plus (COTS+) applications.
