Gowanda’s 17S474K is a high-quality, reliable molded shielded RF coil designed for demanding applications. With a weight of 0.7 grams and compact dimensions of 10.414 × 4.115 × 4.115 mm, it is part of the 17S series and features through-hole technology (THT) mounting. This component is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 4700 µH and a minimum Q factor of 45 at a test frequency of 0.25 MHz. It has a DC resistance of 81.6 ohms and a self-resonant frequency of 0.74 MHz, with a current rating of 0.031 A DC. The device can withstand a dielectric withstanding voltage (DWV) of 1000 volts and has a tolerance of ±10%. It features a lead-based termination type with a Sn63Pb37 finish and a ferrite core, ensuring effective shielding. The 17S474K operates within a temperature range of -55°C to +105°C, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging. However, it is not fungal inert.
