Gowanda’s 21M561J 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 belongs to the 21M series. It is a through-hole technology (THT) component with a commercial off-the-shelf (COTS) application grade. The coil offers an inductance of 5.6 µH with a minimum Q factor of 35, tested at a frequency of 7.9 MHz. It has a direct current resistance (DCR) of 0.13 Ω and a self-resonant frequency (SRF) of 55 MHz, with a current rating of 0.885 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, and it has a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and it utilizes a powdered iron core. Operating within a temperature range of -55°C to +105°C, the component is fungal inert and has a moisture sensitivity level (MSL) of 1, packaged in tape and reel (T&R) format.
