21M392K

Gowanda’s 21M392K is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing 1.7 grams and measuring 14.224 × 5.588 × 5.588 mm, this component is part of the 21M series and features through-hole technology (THT) for mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 39 µH with a minimum Q factor of 70 at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 2 ohms and a self-resonant frequency (SRF) of 18 MHz, with a current rating of 0.224 A DC. It can withstand a dielectric withstanding voltage (DWV) of 1000, 200 and has a tolerance of ±10%. The termination type is lead-based with a Sn63Pb37 finish, and it features a powdered iron core. Operating efficiently between -55°C and +105°C, the coil is rated MSL 1 and is packaged in tape and reel (T&R) format, ensuring fungal inertness for enhanced durability.
