Gowanda’s SMRF1210S-331G is a molded shielded inductor designed for high reliability in electronic applications. Weighing just 0.05 grams, it features compact dimensions of 3 × 2.16 × 2.06 mm, making it suitable for space-constrained environments. This inductor is part of the SMRF1210S series and is mounted using surface-mount technology (SMT). It is classified as COTS+ application grade, ensuring enhanced performance and reliability. With an inductance of 3.3 µH, a DCR of 0.8 Ω, and a current rating of 0.449 A DC, it operates efficiently within a frequency range, boasting a self-resonant frequency (SRF) of 45 MHz and a test frequency of 7.9 MHz. The inductor has a minimum Q factor of 40 and a tolerance of ±2%. It features a Pb termination type with a Sn63Pb37 finish and is constructed with a ferrite core. Although not shielded, it operates within a temperature range of -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 various demanding applications.
