Gowanda’s 22M244GLF is a high-quality, reliable molded unshielded RF coil designed for various applications, particularly in the COTS grade. With a weight of 1.7 grams and dimensions of 14.224 × 5.461 × 5.461 mm, this component is suitable for through-hole technology (THT) mounting. It features an inductance of 2400 µH, a minimum Q factor of 70, and operates at a test frequency of 0.25 MHz. The coil has a direct current resistance (DCR) of 31 ohms and a self-resonant frequency (SRF) of 1.9 MHz, with a current rating of 0.064 A DC. It is designed to withstand dielectric withstanding voltages (DWV) of 180 and 700, with a tolerance of ±2%. The termination type is RoHS compliant with a Sn/Cu finish, and it utilizes a powdered iron core. The component is not shielded, operates within a temperature range of -55°C to +105°C, and has a moisture sensitivity level (MSL) of 1. It is packaged in tape and reel (T&R) and is fungal inert, ensuring durability and reliability in various environments.
