Gowanda’s 15M391K is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil weighs 0.65 grams and measures 9.525 × 3.962 × 3.962 mm, making it compact yet efficient. Part of the 15M series, it features a through-hole mounting type and is suitable for commercial off-the-shelf (COTS) applications. With an inductance of 3.9 µH and a minimum Q factor of 33 at a test frequency of 7.9 MHz, it ensures optimal performance. The coil has a DC resistance of 2.3 ohms, a self-resonant frequency of 100 MHz, and a current rating of 0.28 A DC. It can withstand a dielectric withstanding voltage of 1000 volts and operates within a temperature range of -55°C to +125°C. The component has a tolerance of ±10% and features leaded terminations with a Sn63Pb37 finish. Its phenolic core and fungal inertness enhance durability, while its MSL 1 rating and tape-and-reel packaging facilitate handling and storage.
