SMRF1210S-391K

Gowanda’s SMRF1210S-391K 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 is classified as COTS+ grade, offering an inductance of 3.9 µH with a direct current resistance (DCR) of 0.83 Ω and a current rating of 0.441 A DC. The inductor operates at a self-resonant frequency (SRF) of 42 MHz and is tested at a frequency of 7.9 MHz, with a minimum quality factor (Q MIN) of 40 and a tolerance of ±10%. It features a lead-based termination type with a Sn63Pb37 finish and a ferrite core, although it is not shielded. The operating temperature range is from -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, the inductor is also fungal inert, ensuring durability and reliability in various environments.
