21M392J

Gowanda’s 21M392J 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 dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±5%. The termination type is lead-based (Pb) with a finish of Sn63Pb37, and it uses a powdered iron core. Operating in temperatures ranging from -55°C to +105°C, the coil is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
