Gowanda’s 21M101G is a high-quality molded unshielded RF coil designed for reliable performance in various applications. Weighing 1.7 grams, this component features dimensions of 14.224 × 5.588 × 5.588 mm and is 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. 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 withstanding voltage (DWV) is rated at 1000, 200, and it has a tolerance of ±2%. The termination type is lead-based with a Sn63Pb37 finish, and the core material is phenolic. The component is not shielded and operates within a temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. It is packaged in tape and reel (T&R) and is fungal inert.
