The component is rated for a power dissipation of 800 Watts and utilizes a flange mount configuration for secure installation. Designed for high-power RF applications, it operates within the frequency range of 0 Hz to 1 GHz.
Feature Summary
- High power handling capability suitable for demanding RF environments
- Flange mount design ensures stable mechanical integration
- Broadband operation covering DC to 1 GHz frequencies
Applications
- RF power testing and measurement equipment
- High-power signal termination in communication systems
- Load bank applications for transmitter characterization
Procurement Notes
Verify current product status as this specific part number is listed as obsolete by major distributors. Confirm availability through secondary markets or authorized surplus channels if immediate procurement is required. Ensure compatibility with existing thermal management infrastructure due to the high power rating.
Selection Notes
Select this component only when an 800W power rating and 100 Ohm impedance are strictly required for RF termination. Consider the physical dimensions of the flange mount for panel cutout requirements. Evaluate alternative active or passive loads if the obsolete status prevents long-term supply assurance.
Part Context
This resistor belongs to Bourns' high-power RF termination series, designed for robust performance in industrial and telecommunications settings. These components typically serve as dummy loads for amplifiers and transmitters, ensuring safe energy dissipation during testing phases without connecting to actual antennas or downstream circuitry.
Replacement Considerations
As the CHF190104CBF101R is marked obsolete, direct substitutes may be limited. Review other models within the CHF190104CBF series or comparable high-wattage RF terminators from alternative manufacturers that match the 100 Ohm value and 800W power rating.
