Gowanda’s 15M103K 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. It belongs to the 15M series and features through-hole technology (THT) mounting, making it suitable for commercial off-the-shelf (COTS) applications. With an inductance of 100 µH and a minimum Q factor of 50, it operates at a test frequency of 2.5 MHz. The coil has a DC resistance of 4.5 ohms and a self-resonant frequency of 9.5 MHz, with a current rating of 0.133 A DC. It can withstand a dielectric withstanding voltage (DWV) of 1000 volts and offers a tolerance of ±10%. The termination type is lead-based with a Sn63Pb37 finish, and it uses a powdered iron core. The component is not shielded but is fungal inert and operates within a temperature range of -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1 and is available in tape and reel (T&R) packaging.
