Gowanda’s ER18M510JR is a high-quality M39010 Level-R molded unshielded inductor, designed for reliable performance in demanding applications. With a weight of 0.85 grams and compact dimensions of 10.34 × 3.99 × 3.99 mm, it is part of the ER18M series and features through-hole technology (THT) for mounting. This inductor is QPL application grade, offering an inductance of 0.51 µH, a DCR of 0.125 Ω, and a current rating of 1450 A DC. It operates with a self-resonant frequency (SRF) of 270 MHz and a test frequency of 25 MHz, ensuring a Q MIN of 50. The device is rated for a dielectric withstanding voltage (DWV) of 1000, 200, and maintains a tolerance of ±5%. It is classified as Product Level R, Class 1, with a phenolic core and non-shielded design. The inductor’s termination type is Pb with a Sn63Pb37 finish, suitable for operating temperatures ranging from -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format, though it is not fungal inert.
