7447908

The Würth Elektronik 7447908 is a surface mount multilayer inductor designed for general electronic equipment. It offers an inductance of 10 µH with ±10% tolerance, measured at 2 MHz. The inductor provides a minimum quality factor (Q) of 50 at 2 MHz, ensuring efficient energy storage and minimal losses. The self-resonant frequency is a minimum of 28 MHz, indicating suitability for high-frequency applications. With a maximum DC resistance of 1 Ω, it maintains low power dissipation. The rated current is 15 mA for a 20 K temperature rise and 715 mA for a 40 K rise, allowing flexible use depending on thermal requirements. The operating temperature range is -55°C to +125°C, with ambient temperature for rated current from -55°C to +85°C. This unshielded inductor uses a nickel zinc ferrite core material and is housed in a 0805 (2012 metric) package with dimensions 2.00 mm x 1.25 mm x 1.45 mm. It is supplied in tape and reel packaging with quantities of 3000 to 4000 pieces per reel. Typical applications include RF circuits, filtering, and impedance matching in communication devices, power supplies, and other electronic systems where stable inductance and high Q are required. The component is compliant with RoHS, REACH, and halogen-free standards, and has a moisture sensitivity level of 1.
