Gowanda’s 17S391K is a high-quality molded shielded RF coil designed for reliable performance in various electronic applications. With a weight of 0.7 grams and compact dimensions of 10.414 × 4.115 × 4.115 mm, this component is part of the 17S series and features a through-hole mounting type. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 3.9 µH and a minimum Q factor of 44 at a test frequency of 7.9 MHz. The coil has a DC resistance of 0.4 ohms and a self-resonant frequency of 75 MHz, with a current rating of 0.45 A DC. It can withstand a dielectric withstanding voltage of 1000 volts and has a tolerance of ±10%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron, providing effective shielding. It operates within a temperature range of -55°C to +105°C, has a moisture sensitivity level of 1, and is packaged in tape and reel format. However, it is not fungal inert.
