Gowanda’s ER15M391JR is a high-quality, reliable electronic component from their M39010 Level-R Molded Unshielded Inductor series. Weighing 0.85 grams and measuring 9.27 × 3.71 × 3.71 mm, this inductor is designed for through-hole technology (THT) mounting and is suitable for QPL application grades. It features an inductance of 3.9 µH, a direct current resistance (DCR) of 2.3 Ω, and a current rating of 280 A DC. The inductor operates at a self-resonant frequency (SRF) of 100 MHz with a test frequency of 7.9 MHz and a minimum quality factor (Q MIN) of 33. It has a dielectric withstanding voltage (DWV) of 1000, 300 and a tolerance of ±5%. Classified as a Product Level R, Class 1 component, it has a lead-based termination type with a Sn63Pb37 finish and a phenolic core. The inductor is not shielded and operates within a temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. It is packaged in tape and reel (T&R) format and is not fungal inert.
