Gowanda’s 8M821J is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil weighs 0.25 grams and has compact dimensions of 5.08 × 1.98 × 1.98 mm. Part of the 8M series, it features a through-hole mounting type and is suitable for commercial off-the-shelf (COTS) applications. With an inductance of 8.2 µH and a minimum Q factor of 45, it operates at a test frequency of 7.9 MHz. The coil has a DC resistance of 4.4 ohms, a self-resonant frequency of 52 MHz, and a current rating of 0.104 A DC. It is designed to withstand dielectric withstanding voltages of 1000 and 200, with a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and it uses a powdered iron core. The component is not shielded and operates within a temperature range of -55°C to +105°C. It has a moisture sensitivity level of 1 and is packaged in tape and reel format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
