Gowanda’s MLRF15M221K is a M15305 qualified molded unshielded coil inductor, part of the MLRF15M series, designed for high-quality, reliable electronic applications. With a weight of 0.7 grams and dimensions of 9.27 × 3.71 × 3.71 mm, this through-hole technology (THT) component is suitable for QPL-grade applications. It features an inductance of 2.2 µH, a direct current resistance (DCR) of 0.95 Ω, and a current rating of 0.435 A DC. The inductor operates at a self-resonant frequency (SRF) of 135 MHz and a test frequency of 7.9 MHz, with a minimum Q factor of 33. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±10%. The product level is M, with lead (Pb) termination and a Sn63Pb37 finish. The core is made of phenolic material, and it is not shielded. It operates within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
