Feature Summary

• Capable of handling high continuous power loads up to 800 watts
• Operates effectively across a broad frequency spectrum from DC to 1 GHz
• Constructed with a flange mount design for secure chassis attachment

Applications

• RF power termination in high-frequency circuits
• Load testing for RF amplifiers and transmitters
• Impedance matching networks requiring high power dissipation

Procurement Notes

Verify the specific suffix codes against official Bourns documentation to confirm exact tolerance and package variations. Ensure that the procurement channel provides authentic manufacturer data sheets. Confirm thermal management requirements align with the 800W rating before ordering. Check for any specific environmental certifications if required by the end application standards.

Selection Notes

Select this component when high power dissipation at RF frequencies is critical. The 50-ohm value is standard for impedance matching systems. Consider the flange mounting style for mechanical stability and heat transfer efficiency. Evaluate the 1 GHz bandwidth limit to ensure compatibility with the target signal frequencies. Compare physical footprint constraints against available chassis space.

Part Context

This part belongs to the CHF190104CBF series of high-power RF resistors. These components are engineered for demanding radio frequency environments where standard resistors would fail due to thermal or frequency limitations. The series emphasizes durability and consistent performance under high load conditions, making them suitable for industrial and communication infrastructure.

Replacement Considerations

Consult official Bourns substitution guides for direct equivalents. Verify that any alternative maintains the 800W power rating and 1 GHz frequency capability. Ensure the replacement supports flange mounting and matches the 50-ohm resistance value precisely.
