CHF8838CNF500L

Overview

The Bourns CHF8838CNF500L is a chassis-mounted RF fixed resistor designed for high-frequency applications. It features a resistance value of 50 Ohms with a tolerance of ±5%. The component has a rated power of 150 Watts and operates within a frequency range of 0 Hz to 3 GHz. It utilizes a flat box terminator package style and employs flange mounting for secure installation.

Feature Summary

Designed for high-frequency RF signal termination
Chassis-mounted construction for thermal management
Fixed resistance value suitable for impedance matching

Applications

RF power amplifier output termination
High-frequency signal testing equipment
Communication system load matching

Procurement Notes

Verify the specific part number suffix against official Bourns documentation, as variations may exist in tolerance or power rating. Confirm current product status, as this model may be obsolete or superseded by newer series. Ensure compatibility with existing chassis mounting hardware and thermal interface requirements before procurement.

Selection Notes

Select this component when a 50-Ohm termination is required for frequencies up to 3 GHz. Consider the 150W power handling capability for high-power RF environments. Evaluate the flange mount style against available panel space and cooling constraints. Verify that the ±5% tolerance meets the system's impedance accuracy requirements.

Part Context

This resistor belongs to the CHF series of chassis-mounted RF resistors from Bourns. These components are engineered for robust performance in demanding RF environments. The series offers various power ratings and resistance values to suit different application needs, providing reliable termination for high-frequency signals.

Replacement Considerations

Check for direct replacements within the CHF series or updated Bourns RF resistor lines. Verify that any substitute matches the 50 Ohm resistance, 150W power rating, and 3 GHz frequency limit. Ensure physical dimensions and mounting hole patterns are compatible with existing designs.
