Gowanda’s SMRF1812S-823M 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 surface-mount technology (SMT) component is part of the SMRF1812S series and is suitable for COTS+ grade applications. It features an inductance of 820 µH, a direct current resistance (DCR) of 25.1 Ω, and a current rating of 0.089 A DC, with a saturation current of 0.041 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 2.2 MHz and a test frequency of 0.79 MHz, maintaining a minimum Q factor of 40. It offers a tolerance of ±20% and utilizes a ferrite core for enhanced performance. The component is shielded, operates within a temperature range of -55°C to +125°C, and is rated at moisture sensitivity level (MSL) 1. It features lead (Pb) termination with a Sn63Pb37 finish, is packaged in tape and reel (T&R) format, and is fungal inert, ensuring durability and reliability in various environments.
