Gowanda’s ER17S431JR is a high-quality, reliable electronic component, specifically a M39010 Level-R Molded Shielded Inductor. This component weighs 1.13 grams and has dimensions of 9.91 × 3.86 × 3.86 mm. It belongs to the ER17S series and is designed for through-hole technology (THT) mounting. It is suitable for QPL application grade, offering an inductance of 4.3 µH with a direct current resistance (DCR) of 0.55 ohms and a current rating of 380 A DC. The self-resonant frequency (SRF) is 70 MHz, with a test frequency of 7.9 MHz and a minimum quality factor (Q MIN) of 44. It has a dielectric withstanding voltage (DWV) of 1000, 200, and a tolerance of ±5%. The product is classified as Level R, Class 1, with lead (Pb) termination and a Sn63Pb37 termination finish. It features a powdered iron core and is shielded, operating effectively within a temperature range of -55°C to +105°C. The component has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format, though it is not fungal inert.
