Gowanda’s MLRF17S391K is a M15305 qualified molded shielded coil inductor, known for its high quality and reliability. This component, part of the MLRF17S series, features a weight of 1 gram and dimensions of 9.91 × 3.86 × 3.86 mm. It is designed for through-hole technology (THT) mounting and is suitable for QPL application grades. With an inductance of 3.9 µH, a direct current resistance (DCR) of 0.4 Ω, and a current rating of 450 A DC, it operates efficiently within a frequency range, boasting a self-resonant frequency (SRF) of 75 MHz and a test frequency of 7.9 MHz. The inductor has a minimum Q factor of 44, a dielectric withstanding voltage (DWV) of 1000, 200, and a tolerance of ±10%. It is constructed with a powdered iron core and features lead (Pb) termination with a Sn63Pb37 finish. The product is shielded, operates within a temperature range of -55°C to +105°C, and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), it is also fungal inert, ensuring durability and performance in various environments.
