Gowanda’s ER18M391KP is a high-quality, reliable electronic component from their M39010 Level-R Molded Unshielded Inductor series. This component weighs 0.85 grams and measures 10.34 × 3.99 × 3.99 mm, designed for through-hole technology (THT) mounting. It is a QPL application grade product with an inductance of 3.9 µH, a direct current resistance (DCR) of 0.155 ohms, and a current rating of 870 A DC. The self-resonant frequency (SRF) is 65 MHz, with a test frequency of 7.9 MHz and a minimum Q factor of 30. It features a dielectric withstanding voltage (DWV) of 1000, 200, and a tolerance of ±10%. The product is classified as Level P, Class 1, with lead-based (Pb) termination and a Sn63Pb37 finish. It utilizes a powdered iron core and is not 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.
