Gowanda’s ER18M431JM is a high-quality, reliable electronic component designed for demanding applications. This M39010 Level-R molded unshielded inductor features a compact design with dimensions of 10.34 × 3.99 × 3.99 mm and a weight of 0.85 g. It is part of the ER18M series and is suitable for through-hole technology (THT) mounting. With an inductance of 4.3 µH and a direct current resistance (DCR) of 0.21 Ω, it supports a current rating of 745 A DC. The inductor operates effectively within a frequency range, boasting a self-resonant frequency (SRF) of 60 MHz and a test frequency of 7.9 MHz, with a minimum Q factor of 30. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±5%. The product is classified as Level M, Class 1, and features a Pb termination type with a Sn63Pb37 finish. Constructed with a powdered iron core, it operates within a temperature range of -55°C to +105°C and has a moisture sensitivity level (MSL) of 1. The inductor is packaged in tape and reel (T&R) format, though it is not fungal inert.
