Gowanda’s SMRF1812-333KLF 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 330 µH with a direct current resistance (DCR) of 14 Ω and a current rating of 0.12 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 3.5 MHz and a test frequency of 0.79 MHz, ensuring a minimum quality factor (Q MIN) of 40. It is built to meet COTS+ application grade standards, with a tolerance of ±10% and a RoHS-compliant termination finish of Sn100. The core is made of ferrite, and the component is designed to function in extreme temperatures ranging from -55°C to +125°C. Additionally, it is fungal inert and comes in tape and reel (T&R) packaging, with a moisture sensitivity level (MSL) of 1.
