Gowanda’s 22M274M is a high-quality, reliable molded unshielded RF coil designed for various electronic applications. This component, part of the 22M series, features a compact design with dimensions of 14.224 × 5.461 × 5.461 mm and a weight of 1.7 g. It is suitable for through-hole technology (THT) mounting and is classified under Commercial Off-The-Shelf (COTS) application grade. The coil offers an inductance of 2700 µH with a minimum Q factor of 70, tested at a frequency of 0.25 MHz. It has a direct current resistance (DCR) of 33 Ω and a self-resonant frequency (SRF) of 1.8 MHz, with a current rating of 0.062 A DC. The dielectric withstanding voltage (DWV) is rated at 180, 700, and it operates within a temperature range of -55°C to +105°C. The coil is made with a powdered iron core and features a lead (Pb) termination type with a Sn63Pb37 finish. It is packaged in tape and reel (T&R) format, has a moisture sensitivity level (MSL) of 1, and is fungal inert, ensuring durability and reliability in various environments.
