Gowanda’s 21M122J is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. This component, 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 suitable for through-hole technology (THT) mounting and is classified under the Commercial Off-The-Shelf (COTS) application grade. The coil offers an inductance of 12 µH with a minimum Q factor of 45, tested at a frequency of 2.5 MHz. It has a direct current resistance (DCR) of 0.45 Ω and a self-resonant frequency (SRF) of 34 MHz, with a current rating of 0.465 A DC. The dielectric withstanding 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 is made of powdered iron. The component is not shielded and operates effectively within a temperature range of -55°C to +105°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format. Additionally, the 21M122J is fungal inert, ensuring durability and reliability in various environments.
