Gowanda’s 8M221M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils, part of the 8M series, feature a compact design with dimensions of 5.08 × 1.98 × 1.98 mm and a weight of 0.25 g. They are suitable for through-hole technology (THT) mounting and are classified as Commercial Off-The-Shelf (COTS) grade. With an inductance of 2.2 µH and a minimum Q factor of 45, these coils operate effectively at a test frequency of 7.9 MHz. They have a direct current resistance (DCR) of 0.72 Ω and a self-resonant frequency (SRF) of 130 MHz, supporting a current rating of 0.257 A DC. The coils are constructed with a powdered iron core and have a dielectric withstanding voltage (DWV) of 1000, 200. They offer a tolerance of ±20% and feature Pb termination with a Sn63Pb37 finish. Operating within a temperature range of -55°C to +105°C, these coils are moisture sensitivity level (MSL) 1 rated and packaged in tape and reel (T&R) format. Additionally, they are fungal inert, ensuring durability and reliability in various environments.
