SMRF1210S-471J

Gowanda’s SMRF1210S-471J 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 an inductance of 4.7 µH, 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. It offers a minimum quality factor (Q MIN) of 40 and a tolerance of ±5%. The termination type is lead-based (Pb) with a finish of Sn63Pb37, and it utilizes a ferrite core. Although not shielded, it is designed to operate in temperatures ranging from -55°C to +125°C and is classified with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is also fungal inert, making it suitable for commercial off-the-shelf plus (COTS+) applications.
