Gowanda’s 21M560J is a high-quality molded unshielded RF coil designed for reliable performance in various applications. Weighing 1.7 grams and measuring 14.224 × 5.588 × 5.588 mm, this component is part of the 21M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 0.56 µH with a minimum Q factor of 65 at a test frequency of 25 MHz. The coil has a direct current resistance (DCR) of 0.08 ohms and a self-resonant frequency (SRF) of 270 MHz, with a current rating of 1.85 A DC. It is capable of withstanding dielectric withstanding voltages (DWV) of 1000 and 200 volts. The component has a tolerance of ±5% and features lead-based (Pb) terminations with a Sn63Pb37 finish. Constructed with a phenolic core, it is not shielded and operates effectively 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) format and is fungal inert, ensuring durability and reliability in demanding environments.
