Gowanda’s 19M104K is a high-quality molded unshielded RF coil designed for reliable performance in various applications. Weighing 1.3 grams, it features dimensions of 11.176 × 4.826 × 4.826 mm and belongs to the 19M series. This component is mounted using through-hole technology (THT) and is suitable for commercial off-the-shelf (COTS) applications. It offers an inductance of 1000 µH with a minimum Q factor of 60, tested at a frequency of 0.79 MHz. The coil has a DC resistance of 16.5 ohms and a self-resonant frequency of 2.8 MHz, with a current rating of 0.078 A DC. It can withstand a dielectric withstanding voltage (DWV) of 180 volts and has a tolerance of ±10%. The termination type is lead-based with a Sn63Pb37 finish, and it uses a powdered iron core. The coil is not shielded and operates within a temperature range of -55°C to +105°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability in various environments.
