Gowanda’s SMRF1812T-821J is a high-quality, reliable molded unshielded temperature stable inductor designed for demanding applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812T series and features surface mount technology (SMT) for easy integration. It is classified as COTS+ grade, ensuring suitability for commercial off-the-shelf applications. With an inductance of 8.2 µH, a direct current resistance (DCR) of 1.6 Ω, and a current rating of 0.333 A DC, it operates efficiently across a frequency range with a self-resonant frequency (SRF) of 25 MHz and a test frequency of 7.9 MHz. The inductor offers a minimum Q factor of 25 and a tolerance of ±5%. It utilizes a powdered iron core and features lead (Pb) termination with a Sn63Pb37 finish. Operating reliably in temperatures from -55°C to +125°C, it is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability in various environments.
