28M471M

Gowanda’s 28M471M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. 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 mounted using Through-Hole Technology (THT). With an inductance of 4.7 µH and a minimum Q factor of 60, these coils are suitable for COTS-grade applications. They operate at a test frequency of 7.9 MHz, with a DC resistance of 0.56 Ω and a self-resonant frequency of 90 MHz. The current rating is 0.86 A DC, and they can withstand dielectric withstanding voltages of 1000 and 200. The coils have a tolerance of ±20% and feature Pb termination with a Sn63Pb37 finish. Constructed with a phenolic core, they are not shielded but are fungal inert and have an operating temperature range from -55°C to +105°C. They are rated at MSL 1 and are available in tape and reel packaging.
