Gowanda’s 21M271JLF is a high-quality molded unshielded RF coil designed for reliable performance in various applications. With a weight of 1.7 grams and dimensions of 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 2.7 µH with a minimum Q factor of 40 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.65 ohms and a self-resonant frequency (SRF) of 120 MHz, with a current rating of 0.6 A DC. It can withstand dielectric withstanding voltages (DWV) of 1000 and 200 volts, with a tolerance of ±5%. The termination type is RoHS compliant with a Sn/Cu finish, and the core is made of phenolic material. The component operates effectively in temperatures ranging from -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in demanding environments.
