Gowanda’s 17S391M is a high-quality, reliable molded shielded RF coil designed for various applications, featuring a compact size with dimensions of 10.414 × 4.115 × 4.115 mm and a weight of 0.7 g. This component is part of the 17S series and is suitable for through-hole technology (THT) mounting. It is categorized under Commercial Off-The-Shelf (COTS) application grade, 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, with a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and it is constructed with a powdered iron core, 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.
