Gowanda’s 21M470M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 1.7 grams and have dimensions of 14.224 × 5.588 × 5.588 mm. They belong to the 21M series and are mounted using Through-Hole Technology (THT). With an inductance of 0.47 µH and a minimum Q factor of 65, these coils are suitable for COTS application grades. They operate at a test frequency of 25 MHz, with a DCR of 0.06 Ω and a self-resonant frequency of 300 MHz. The current rating is 1.97 A DC, and they have a dielectric withstanding voltage of 1000, 200. The coils feature a tolerance of ±20%, use Pb termination type with Sn63Pb37 finish, and have a phenolic core. They are not shielded and can operate in temperatures ranging from -55°C to +125°C. With a moisture sensitivity level of 1, these coils are packaged in tape and reel and are fungal inert.
