Gowanda’s 17S391GLF is a high-quality molded shielded RF coil designed for reliable performance in electronic applications. Weighing 0.7 grams and measuring 10.414 × 4.115 × 4.115 mm, this component is part of the 17S series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 3.9 µH with a minimum Q factor of 44 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.4 Ω and a self-resonant frequency (SRF) of 75 MHz, with a current rating of 0.45 A DC. It is designed to withstand a dielectric withstanding voltage (DWV) of 1000 volts and has a tolerance of ±2%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of powdered iron, providing effective shielding. The operating temperature range is from -55°C to +105°C, with a moisture sensitivity level (MSL) of 1, and it is packaged in tape and reel (T&R) format. However, it is not fungal inert.
