Gowanda’s 21M101J is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil, part of the 21M series, features a compact design with dimensions of 14.224 × 5.588 × 5.588 mm and a weight of 1.7 g. It is tailored for through-hole technology (THT) mounting and is suitable for commercial off-the-shelf (COTS) applications. The coil offers an inductance of 1 µH with a minimum Q factor of 65, tested at a frequency of 25 MHz. It has a direct current resistance (DCR) of 0.14 Ω and a self-resonant frequency (SRF) of 200 MHz, with a current rating of 1.29 A DC. The dielectric withstand voltage (DWV) is rated at 1000, 200, and it maintains a tolerance of ±5%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and the core material is phenolic. It operates efficiently 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, the component is fungal inert, ensuring reliability in various environments.
