Gowanda’s ER10M303JR is a high-quality, reliable electronic component from their M39010 Level-R Molded Unshielded Inductor series. This inductor features a compact design with dimensions of 6.1 × 2.16 × 2.16 mm and a weight of 0.283 g. It is designed for through-hole technology (THT) mounting and is suitable for QPL application grades. With an inductance of 300 µH, a direct current resistance (DCR) of 28 Ω, and a current rating of 45 A DC, it is engineered for robust performance. The inductor operates within a frequency range with a self-resonant frequency (SRF) of 7 MHz and a test frequency of 0.79 MHz, ensuring a minimum Q factor of 30. It is built to withstand dielectric withstanding voltages (DWV) of 1000, 200, and 300, with a tolerance of ±5%. The product is classified as Level R, Class 1, with lead (Pb) termination and a Sn63Pb37 finish. It utilizes a ferrite core and is not shielded, operating efficiently in temperatures ranging from -55°C to +105°C. The inductor is rated with a moisture sensitivity level (MSL) of 1 and is available in tape and reel (T&R) packaging, though it is not fungal inert.
