Gowanda’s 21M182K is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil weighs 1.7 grams and measures 14.224 × 5.588 × 5.588 mm. It belongs to the 21M series and features through-hole technology (THT) mounting, making it suitable for commercial off-the-shelf (COTS) applications. With an inductance of 18 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 0.7 ohms and a self-resonant frequency of 28 MHz, with a current rating of 0.38 A DC. It can withstand dielectric withstanding voltages of 1000 and 200, with 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 and operates within a temperature range of -55°C to +105°C, with a moisture sensitivity level of 1. It is packaged in tape and reel (T&R) and is fungal inert, ensuring durability and reliability in various environments.
