Gowanda’s SMRF1812-683K is a molded unshielded inductor designed for high reliability in demanding applications. This component, part of the SMRF1812 series, features a compact size with dimensions of 4.064 × 3 × 2.9 mm and a weight of 0.15 g, making it suitable for surface mount technology (SMT). It offers an inductance of 680 µH with a direct current resistance (DCR) of 30 Ω and a current rating of 0.082 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 3 MHz and a test frequency of 0.79 MHz, ensuring a minimum Q factor of 30. It is built with a ferrite core and has a termination finish of Sn63Pb37, providing a tolerance of ±10%. The SMRF1812-683K is designed to withstand extreme temperatures from -55°C to +125°C and is classified as moisture sensitivity level (MSL) 1, ensuring durability and reliability. Additionally, it is fungal inert and packaged in tape and reel (T&R) format, making it ideal for commercial off-the-shelf (COTS) applications.
