Gowanda’s SMRF1812S-182M is a molded shielded inductor designed for high reliability in electronic applications. Weighing 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812S series and is suitable for surface mount technology (SMT). It features an inductance of 18 µH with a direct current resistance (DCR) of 0.962 ohms and a current rating of 0.456 A DC. The saturation current is 0.254 A DC, and it has a self-resonant frequency (SRF) of 15 MHz, tested at 2.5 MHz with a minimum Q factor of 50. The inductor is constructed with a ferrite core and is shielded, ensuring minimal electromagnetic interference. It operates effectively within a temperature range of -55°C to +125°C and is rated MSL 1 for moisture sensitivity. The termination type is lead-based with a Sn63Pb37 finish, and it is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, making it suitable for various demanding environments.
