Gowanda’s ER17S303JM is a high-quality, reliable molded shielded inductor designed for demanding applications. Part of the ER17S series, this inductor features a compact design with dimensions of 9.91 × 3.86 × 3.86 mm and a weight of 1.13 g. It is tailored for through-hole technology (THT) mounting and meets QPL application grade standards. With an inductance of 300 µH, a DCR of 6.4 Ω, and a current rating of 110 A DC, it is suitable for high-performance environments. The inductor operates efficiently across a frequency range, with a self-resonant frequency (SRF) of 6.5 MHz and a test frequency of 0.79 MHz. It boasts a minimum Q factor of 55 and a dielectric withstanding voltage (DWV) of 1000, 200. The product is classified as Level M, Class 1, with a tolerance of ±5%. It features a ferrite core and is shielded for enhanced performance. The termination type is Pb with a Sn63Pb37 finish, and it operates within a temperature range of -55°C to +105°C. The inductor is packaged in tape and reel (T&R) and has a moisture sensitivity level (MSL) of 1, although it is not fungal inert.
