Gowanda’s 10M391J is a high-quality molded unshielded RF coil designed for reliable performance in various applications. With a compact weight of 0.3 grams and dimensions of 6.35 × 2.413 × 2.413 mm, it belongs to the 10M series and features through-hole technology (THT) mounting. This component is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 3.9 µH and a minimum Q factor of 45 at a test frequency of 7.9 MHz. It has a direct current resistance (DCR) of 1 ohm and a self-resonant frequency (SRF) of 80 MHz, with a current rating of 250 A DC. The device can withstand a dielectric withstanding voltage (DWV) of 300 volts and maintains a tolerance of ±5%. Its powdered iron core and Sn63Pb37 termination finish ensure durability, while its operating temperature range of -55°C to +105°C and MSL 1 rating highlight its robustness. Packaged in tape and reel (T&R) format, the 10M391J is also fungal inert, making it a reliable choice for demanding environments.
