Gowanda’s ER10M471KM is a high-quality M39010 Level-R molded unshielded inductor, designed for reliable performance in demanding applications. Weighing 0.283 grams and measuring 6.1 × 2.16 × 2.16 mm, this inductor is part of the ER10M series and features through-hole technology (THT) for mounting. It is QPL application grade with an inductance of 4.7 µH, a DCR of 1.2 Ω, and a current rating of 230 A DC. The inductor operates at a self-resonant frequency (SRF) of 75 MHz and a test frequency of 7.9 MHz, with a minimum Q factor of 45. It is built to withstand dielectric withstanding voltages (DWV) of 1000, 200, and 300, with a tolerance of ±10%. The product is classified as Level M, Class 1, with a lead-based termination type and a Sn63Pb37 finish. Constructed with a powdered iron core, it is not shielded and operates within a temperature range of -55°C to +105°C. The inductor has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R), though it is not fungal inert.
