Gowanda’s ER10M391JR is a high-quality, reliable electronic component from the M39010 Level-R Molded Unshielded Inductor series, designed for demanding applications. With a weight of 0.283 g and compact dimensions of 6.1 × 2.16 × 2.16 mm, it features a Through-Hole Technology (THT) mounting type and is QPL application grade. The inductor offers an inductance of 3.9 µH, a direct current resistance (DCR) of 1 Ω, and a current rating of 250 A DC. It operates at a self-resonant frequency (SRF) of 80 MHz and a test frequency of 7.9 MHz, with a minimum Q factor of 45. The device is rated for dielectric withstanding voltages (DWV) of 1000, 200, and 300, with a tolerance of ±5%. It is a Class 1 product with a Pb termination type and Sn63Pb37 termination finish, utilizing 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) and is not fungal inert.
