78FR82K Description

Short technical summary and product information.

The Bourns 78FR82K is a conformal coated RF choke from the 78F series, offering an inductance of 820 nH with ±10% tolerance. It features a ferrite bobbin core with wirewound drum core construction, providing high Q and self-resonant frequency characteristics. The component is rated for a maximum DC current of 415 mA and has a low DC resistance of 120 mOhm, minimizing power loss.

 

This unshielded inductor is designed for through hole mounting in an axial package measuring 0.110 inches in diameter and 0.280 inches in length. The epoxy coating protects the winding from harsh environments, ensuring reliable operation over a wide temperature range from -55°C to 105°C. The inductor achieves a minimum Q factor of 40 at 25 MHz and a self-resonant frequency of 200 MHz, making it suitable for RF applications.

 

Typical applications include RF signal filtering, impedance matching, and DC-DC converter output filtering. The axial leaded package allows for easy insertion into through hole boards, and the color band identification simplifies part recognition during assembly.
