Gowanda’s 8M471M 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 under COTS application grade. With an inductance of 4.7 µH and a minimum Q factor of 55, these coils are optimized for a test frequency of 7.9 MHz. They have a DCR of 2.1 Ω, an SRF of 88 MHz, and a current rating of 0.15 A DC. The coils are designed to withstand a dielectric withstanding voltage of 1000, 200 and have a tolerance of ±20%. They use a powdered iron core and are not shielded, operating effectively within a temperature range of -55°C to +105°C. The termination type is Pb with a Sn63Pb37 finish, and they are packaged in tape and reel format. Additionally, these coils are fungal inert and have an MSL of 1, ensuring durability and reliability in various conditions.
