Gowanda’s ER18M821JR 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 8.2 µH, a direct current resistance (DCR) of 0.44 Ω, and a current rating of 520 A DC. The component operates at a self-resonant frequency (SRF) of 48 MHz and a test frequency of 7.9 MHz, with a minimum Q factor of 30. It features a dielectric withstanding voltage (DWV) of 1000, 200 and a tolerance of ±5%. Classified as a Level R, Class 1 product, it has a lead-based termination type with a Sn63Pb37 finish and a powdered iron core. The inductor is not shielded and operates within a temperature range of -55°C to +105°C, with a moisture sensitivity level (MSL) of 1. It is packaged in tape and reel (T&R) format and is not fungal inert.
