Gowanda’s SMRF1210S-471M is a molded shielded inductor designed for high reliability in electronic applications. Weighing just 0.05 grams and measuring 3 × 2.16 × 2.06 mm, this component is part of the SMRF1210S series and is suitable for surface mount technology (SMT). It features a 4.7 µH inductance with a direct current resistance (DCR) of 1 Ω and a current rating of 0.402 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 40 MHz and a test frequency of 7.9 MHz, maintaining a minimum Q factor of 40. It offers a tolerance of ±20% and uses a Pb termination type with a Sn63Pb37 finish. Constructed with a ferrite core, it is designed to operate in temperatures ranging from -55°C to +125°C and is rated with a moisture sensitivity level (MSL) of 1. The component is packaged in tape and reel (T&R) format and is fungal inert, making it suitable for commercial off-the-shelf plus (COTS+) applications.
