Gowanda’s ER18M471JR is a high-quality, reliable electronic component from the M39010 Level-R Molded Unshielded Inductor series. Weighing 0.85 grams and measuring 10.34 × 3.99 × 3.99 mm, this inductor is designed for through-hole technology (THT) mounting and is suitable for QPL application grades. It features an inductance of 4.7 µH, a direct current resistance (DCR) of 0.21 Ω, and a current rating of 745 A DC. The inductor operates with a self-resonant frequency (SRF) of 60 MHz and a test frequency of 7.9 MHz, with a minimum quality factor (Q MIN) of 30. 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 a lead (Pb) termination type and a Sn63Pb37 termination finish. Made with a powdered iron core, it is not shielded and operates 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. Note that it is not fungal inert.
