21M182M

Gowanda’s 21M182M is a high-quality molded unshielded RF coil designed for reliable performance in various applications. Weighing 1.7 grams and measuring 14.224 × 5.588 × 5.588 mm, this component is part of the 21M series and features a through-hole mounting type. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 18 µH with a minimum Q factor of 50 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 is designed to withstand dielectric withstanding voltages of 1000 and 200, with a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and it utilizes a powdered iron core. Operating within a temperature range of -55°C to +105°C, the coil is rated at moisture sensitivity level 1 and is packaged in tape and reel format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
