SMRF1812S-392M

Gowanda’s SMRF1812S-392M is a molded shielded inductor designed for high reliability in electronic applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812S series and features surface mount technology (SMT) for ease of integration. It is classified as COTS+ grade, ensuring suitability for commercial off-the-shelf applications. With an inductance of 39 µH, a direct current resistance (DCR) of 2.34 Ω, and a current rating of 0.292 A DC, it is engineered for efficient performance. The inductor has a saturation current of 0.174 A DC and a self-resonant frequency (SRF) of 11 MHz, tested at a frequency of 2.5 MHz with a minimum Q factor of 50. It offers a tolerance of ±20% and features lead (Pb) termination with a Sn63Pb37 finish. Constructed with a ferrite core and shielded for reduced electromagnetic interference, 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 a robust choice for demanding environments.
