Gowanda’s 8M220K Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 0.25 grams and have compact dimensions of 5.08 × 1.98 × 1.98 mm, making them suitable for space-constrained environments. Part of the 8M series, they feature a through-hole mounting type and are classified as COTS application grade. With an inductance of 0.22 µH and a minimum Q factor of 30, these coils operate efficiently at a test frequency of 25 MHz. They have a direct current resistance of 0.25 Ω and a self-resonant frequency of 500 MHz, supporting a current rating of 0.645 A DC. The dielectric withstanding voltage is rated at 1000, 200, and they offer a tolerance of ±10%. The termination type is Pb with a Sn63Pb37 finish, and the core is made of phenolic material. These coils are not shielded but are designed to operate within a temperature range of -55°C to +125°C. They have a moisture sensitivity level of 1 and are packaged in tape and reel format. Additionally, they are fungal inert, ensuring durability in various environments.
