Gowanda’s 28M822M Molded Unshielded RF Coils are a testament to the company’s commitment to high-quality, reliable electronic components. These coils weigh 2.65 grams and have dimensions of 22.86 × 7.137 × 7.137 mm. They belong to the 28M series and are designed for through-hole technology (THT) mounting. With an inductance of 82 µH and a minimum Q factor of 75, they are suitable for commercial off-the-shelf (COTS) applications. The coils operate at a test frequency of 2.5 MHz, with a DC resistance of 2.1 ohms and a self-resonant frequency of 12 MHz. They have a current rating of 0.265 A DC and a dielectric withstanding voltage of 1000, 200. The tolerance is ±20%, and they feature a Pb termination type with a Sn63Pb37 finish. Constructed with a powdered iron core, these coils are not shielded and can operate in temperatures ranging from -55°C to +125°C. They have a moisture sensitivity level of 1, are packaged in tape and reel (T&R), and are fungal inert.
