Gowanda’s 21M272J 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. Part of the 21M series, it features a through-hole mounting type and is suitable for commercial off-the-shelf (COTS) applications. With an inductance of 27 µH and a minimum Q factor of 60, it operates at a test frequency of 2.5 MHz. The coil has a DC resistance of 1.3 ohms, a self-resonant frequency of 22 MHz, and a current rating of 0.275 A DC. It can withstand a dielectric withstanding voltage of 1000, 200 and has a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and it uses a powdered iron core. Operating efficiently between -55°C and +105°C, it is rated MSL 1 and is packaged in tape and reel format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
