Gowanda’s 17S394G is a high-quality, reliable molded shielded RF coil designed for demanding applications. Weighing just 0.7 grams, it features compact dimensions of 10.414 × 4.115 × 4.115 mm and is part of the 17S series. This through-hole technology (THT) component is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 3900 µH with a minimum Q factor of 45. It operates at a test frequency of 0.25 MHz and has a direct current resistance (DCR) of 73.8 ohms. The coil’s self-resonant frequency (SRF) is 0.8 MHz, with a current rating of 0.035 A DC and a dielectric withstanding voltage (DWV) of 1000. It boasts a tight tolerance of ±2% and features lead-based termination with a Sn63Pb37 finish. Constructed with a ferrite core and shielded for enhanced performance, it operates within a temperature range of -55°C to +105°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), it is not fungal inert.
