Gowanda’s 10M431J is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. With a compact weight of 0.3 grams and dimensions of 6.35 × 2.413 × 2.413 mm, this component is part of the 10M series and features through-hole technology (THT) for easy mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 4.3 µH and a minimum Q factor of 45 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 1.1 ohms and a self-resonant frequency (SRF) of 77 MHz, with a current rating of 240 mA DC. It can withstand a dielectric withstanding voltage (DWV) of 300 volts and maintains a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. Operating efficiently in temperatures ranging from -55°C to +105°C, the 10M431J is fungal inert and comes in tape and reel (T&R) packaging, with a moisture sensitivity level (MSL) of 1.
