Gowanda’s 19F473J is a high-quality molded unshielded RF coil, part of the 19F series, designed for reliable performance in various applications. This component features a compact design with dimensions of 11.176 × 4.826 × 4.826 mm and a weight of 1.3 g. It is suitable for through-hole technology (THT) mounting and is classified under the Commercial Off-The-Shelf (COTS) application grade. The coil offers an inductance of 470 µH, a direct current resistance (DCR) of 8.3 Ω, and a self-resonant frequency (SRF) of 4 MHz, with a current rating of 0.183 A DC. It operates within a temperature range of -55°C to +125°C and has a dielectric withstanding voltage (DWV) of 200. The component is constructed with a ferrite core and features a termination type of Pb with a Sn63Pb37 finish. It is packaged in tape and reel (T&R) format, though it is not fungal inert.
