Gowanda’s ER18M821JM is a high-quality, reliable electronic component, specifically a M39010 Level-R Molded Unshielded Inductor. It features a weight of 0.85 grams and dimensions of 10.34 × 3.99 × 3.99 mm. This inductor belongs to the ER18M series and is designed for through-hole technology (THT) mounting. It is suitable for QPL application grade with an inductance of 8.2 µH and a direct current resistance (DCR) of 0.44 Ω. The component supports a current rating of 520 A DC and a self-resonant frequency (SRF) of 48 MHz, tested at a frequency of 7.9 MHz with a minimum Q factor of 30. It has a dielectric withstanding voltage (DWV) of 1000, 200 and a tolerance of ±5%. The product is classified as Level M, Class 1, with a lead-based termination type and a Sn63Pb37 termination finish. It utilizes a powdered iron core and is not shielded, operating within a temperature range of -55°C to +105°C. The moisture sensitivity level (MSL) is 1, and it is packaged in tape and reel (T&R) format, though it is not fungal inert.
