Gowanda’s SMRF1210S-391M is a high-quality molded shielded inductor designed for reliable performance 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) applications. It features a COTS+ application grade, with an inductance of 3.9 µH and a direct current resistance (DCR) of 0.83 Ω. The inductor supports a current rating of 0.441 A DC and a self-resonant frequency (SRF) of 42 MHz, tested at a frequency of 7.9 MHz with a minimum Q factor of 40. It offers a tolerance of ±20% and utilizes a lead-based termination type with a Sn63Pb37 finish. The core is made of ferrite, and while it is not shielded, it operates effectively 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) format and is fungal inert, ensuring durability and reliability in various environments.
