Gowanda’s 17S121KLF is a high-quality, reliable molded shielded RF coil designed for demanding 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 1.2 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 0.1 ohms and a self-resonant frequency (SRF) of 130 MHz, supporting a current rating of 0.895 A DC. With a dielectric withstanding voltage (DWV) of 1000, it maintains a tolerance of ±10% and is RoHS compliant with a Sn/Cu termination finish. The core is made of powdered iron, and the component is shielded, operating effectively within a temperature range of -55°C to +105°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format, though it is not fungal inert.
