Gowanda’s 21M152J is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil, part of the Series 21M, 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 15 µH with a Q minimum of 45, tested at a frequency of 2.5 MHz. It has a direct current resistance (DCR) of 0.52 Ω and a self-resonant frequency (SRF) of 32 MHz, with a current rating of 0.442 A DC. The component is built with a powdered iron core and is not shielded, operating efficiently within a temperature range of -55°C to +105°C. It features a dielectric withstanding voltage (DWV) of 1000, 200, and a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and it is packaged in tape and reel (T&R) format. Additionally, the component is fungal inert and has a moisture sensitivity level (MSL) of 1.
