SMRF1812S-393K

Gowanda’s SMRF1812S-393K is a molded shielded inductor designed for high reliability in electronic applications. With a compact size of 4.2 × 3 × 2.9 mm and a weight of 0.15 g, it is suitable for surface mount technology (SMT) applications. This inductor belongs to the SMRF1812S series and is classified as COTS+ grade, ensuring enhanced performance for commercial off-the-shelf applications. It features an inductance of 390 µH, a direct current resistance (DCR) of 12 Ω, and a current rating of 0.129 A DC, with a saturation current of 0.053 A DC. The self-resonant frequency (SRF) is 3.5 MHz, and it is tested at a frequency of 0.79 MHz with a minimum Q factor of 40. The inductor has a tolerance of ±10% and uses a lead (Pb) termination type with a Sn63Pb37 finish. Constructed with a ferrite core and shielded for improved performance, 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 environments.
