Gowanda’s SMRF1812T-681J is a molded unshielded temperature stable inductor designed for high reliability in electronic applications. With a compact weight of 0.15 g and dimensions of 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812T series and is suitable for surface mount technology (SMT). It features an inductance of 6.8 µH, a direct current resistance (DCR) of 1.3 Ω, and a current rating of 0.369 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 27 MHz and a test frequency of 7.9 MHz, ensuring a Q factor of at least 25. It is built with a powdered iron core and has a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and it is rated for operation in temperatures ranging from -55°C to +125°C. The inductor is classified as moisture sensitivity level (MSL) 1, packaged in tape and reel (T&R) format, and is fungal inert, making it ideal for commercial off-the-shelf plus (COTS+) applications.
