Gowanda’s 8M121K is a high-quality, reliable molded unshielded RF coil designed for demanding applications. Weighing just 0.25 grams, it features compact dimensions of 5.08 × 1.98 × 1.98 mm and is part of the 8M series. This through-hole technology (THT) component is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 1.2 µH with a minimum Q factor of 35 at a test frequency of 7.9 MHz. It has a direct current resistance (DCR) of 0.28 Ω and a self-resonant frequency (SRF) of 170 MHz, with a current rating of 0.41 A DC. The device can withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±10%. It features a lead-based termination type with a Sn63Pb37 finish and a powdered iron core. Operating effectively in temperatures ranging from -55°C to +105°C, it is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, the component is fungal inert, ensuring durability and reliability in various environments.
