Gowanda’s ER17S331KR is a high-quality, reliable electronic component from their M39010 Level-R Molded Shielded Inductor series. This component weighs 1.13 grams and measures 9.91 × 3.86 × 3.86 mm, designed for through-hole technology (THT) mounting. It is a QPL application grade product with an inductance of 3.3 µH, a direct current resistance (DCR) of 0.35 Ω, and a current rating of 480 A DC. The inductor features a self-resonant frequency (SRF) of 85 MHz and a test frequency of 7.9 MHz, with a minimum Q factor of 44. It is rated for dielectric withstanding voltage (DWV) of 1000, 200 and has a tolerance of ±10%. The product is classified as Level R, Class 1, with lead (Pb) termination and a Sn63Pb37 finish. It utilizes a powdered iron core and is shielded, operating efficiently within a temperature range of -55°C to +105°C. The component is rated MSL 1 and is packaged in tape and reel (T&R), although it is not fungal inert.
