Gowanda’s 21M101MLF is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil weighs 1.7 grams and features dimensions of 14.224 × 5.588 × 5.588 mm. Part of the 21M series, it is suitable for through-hole technology (THT) mounting and is classified as a Commercial Off-The-Shelf (COTS) application grade. It offers an inductance of 1 µH with a minimum Q factor of 65 at a test frequency of 25 MHz. The coil has a DC resistance of 0.14 Ω and a self-resonant frequency of 200 MHz, with a current rating of 1.29 A DC. It can withstand dielectric withstanding voltages of 1000 and 200, with a tolerance of ±20%. The termination type is RoHS compliant with a Sn/Cu finish, and it features a phenolic core. Operating efficiently between -55°C and +125°C, it is rated at moisture sensitivity level 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
