Gowanda’s SMRF1812T-471KLF is a high-quality, reliable molded unshielded temperature stable inductor designed for demanding applications. With a compact weight of 0.15 g and dimensions of 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812T series and is suitable for surface mount technology (SMT). It features an inductance of 4.7 µH, a direct current resistance (DCR) of 1 Ω, and a current rating of 0.421 A DC. The inductor operates at a self-resonant frequency (SRF) of 35 MHz and is tested at 7.9 MHz with a minimum Q factor of 25. It offers a tolerance of ±10% and is RoHS compliant with a Sn100 termination finish. The core is made of powdered iron, and it is designed to operate within a temperature range of -55°C to +125°C. With a moisture sensitivity level (MSL) of 1, it is packaged in tape and reel (T&R) and is fungal inert, making it ideal for commercial off-the-shelf plus (COTS+) applications.
