Gowanda’s ER17S473KR is a high-quality, reliable M39010 Level-R molded shielded inductor designed for demanding applications. With a weight of 1.13 g and compact dimensions of 9.91 × 3.86 × 3.86 mm, this inductor is part of the ER17S series and features through-hole technology (THT) mounting. It is QPL application grade, offering an inductance of 470 µH, a DCR of 9.5 Ω, and a current rating of 92 A DC. The inductor has a self-resonant frequency (SRF) of 5.7 MHz and a test frequency of 0.79 MHz, with a minimum Q factor of 60. It is designed to withstand a dielectric withstanding voltage (DWV) of 1000, 200 and has a tolerance of ±10%. The product is classified as Level R, Class 1, with a lead-based termination type and a Sn63Pb37 termination finish. The core is made of ferrite and is shielded, suitable for operating temperatures ranging from -55°C to +105°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format, though it is not fungal inert.
