Gowanda’s SMRF1812S-822K is a high-quality molded shielded inductor designed for reliable performance 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 is suitable for surface mount technology (SMT). It features an inductance of 82 µH, a direct current resistance (DCR) of 3.6 Ω, and a current rating of 0.235 A DC, with a saturation current of 0.122 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 7.2 MHz and a test frequency of 2.5 MHz, ensuring a minimum Q factor of 50. It is built with a ferrite core and is shielded, making it ideal for COTS+ grade applications. The component is designed to withstand temperatures from -55°C to +125°C and is packaged in tape and reel (T&R) format. It features a Pb termination type with a Sn63Pb37 finish and is rated MSL 1, indicating high reliability and fungal inertness.
