SMRF1812T-221K

Gowanda’s SMRF1812T-221K is a molded unshielded temperature stable inductor designed for high reliability in electronic applications. Weighing just 0.15 grams and measuring 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 2.2 µH, a DC resistance of 0.66 Ω, and a current rating of 0.518 A DC. With a self-resonant frequency of 56 MHz and a minimum Q factor of 30, it operates effectively within a frequency range tested at 7.9 MHz. The inductor has a tolerance of ±10% and uses a powdered iron core, with a termination type of Pb and a finish of Sn63Pb37. It is capable of functioning in temperatures ranging from -55°C to +125°C and is rated at moisture sensitivity level 1. Packaged in tape and reel (T&R), it is also fungal inert, making it suitable for commercial off-the-shelf plus (COTS+) applications.
