CHF3020CBF500L

Overview

The Bourns CHF3020CBF500L is a chassis-mounted RF power termination resistor designed for high-frequency applications. It features a nominal resistance of 50 Ohms with a tolerance of ±5%. The component has a power rating of 10W and operates effectively from DC to 4 GHz. It utilizes a flanged mounting style for secure installation and thermal dissipation. The physical package dimensions are standardized within the CHF3020 series, ensuring compatibility with standard chassis openings.

Feature Summary

• Flanged chassis mount design for stable mechanical attachment
• High-frequency operation capability up to 4 GHz
• Thick film construction for reliable RF termination

Applications

• RF signal path termination
• High-frequency circuit testing equipment
• Communication system impedance matching

Procurement Notes

Verify current availability status as this model may be subject to discontinuation or limited supply. Confirm that the specific suffix 'L' corresponds to the required lead-free compliance and packaging format. Cross-reference the manufacturer's official datasheet to ensure the 10W power rating and 50 Ohm value match the exact design requirements before ordering.

Selection Notes

Select this component when a 50 Ohm RF termination is required in a chassis-mounted configuration. Ensure the application frequency does not exceed 4 GHz. Verify that the 10W power handling capacity is sufficient for the intended duty cycle. Compare physical dimensions against available chassis space to confirm fitment for the flanged package type.

Part Context

This part belongs to the Bourns CHF Series of RF power resistors. These components are engineered for robust performance in demanding radio frequency environments. The series offers various resistance values and power ratings, with the CHF3020 variant providing a compact form factor suitable for dense panel installations.

Replacement Considerations

Check for direct substitutes within the CHF3020 series offering identical 50 Ohm resistance and 10W rating. Verify that any alternative maintains the same flanged mounting interface and 4 GHz frequency limit. Consult the manufacturer's obsolescence notices for recommended replacement models if this part is discontinued.
