Gowanda’s 21M102JLF 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, making it compact yet efficient. Part of the 21M series, it features a through-hole technology (THT) mounting type and is suitable for commercial off-the-shelf (COTS) applications. With an inductance of 10 µH and a minimum Q factor of 35, it operates at a test frequency of 7.9 MHz. The coil has a DC resistance of 0.26 Ω, a self-resonant frequency of 42 MHz, and a current rating of 0.625 A DC. It can withstand dielectric withstanding voltages of 1000 and 200, with a tolerance of ±5%. The termination type is RoHS compliant with a Sn/Cu finish, and it uses a powdered iron core. Although unshielded, it operates effectively within a temperature range of -55°C to +105°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is also fungal inert, ensuring durability and reliability in various environments.
