Procurement Notes

Verify the current product status, as this specific part number may be listed as obsolete in certain distributor databases. Confirm RoHS compliance and lead-free status through official manufacturer documentation or authorized suppliers before procurement. Ensure that the 12.5 Ohm resistance and 800W power rating align precisely with the design requirements, as substitutes may vary significantly in thermal and electrical performance characteristics.

Selection Notes

Select this component when high-power RF dissipation is required in a chassis-mounted form factor. The 12.5 Ohm value and 5% tolerance suit specific impedance matching or load applications. Consider the physical dimensions, including the 8.80mm height and flange mounting style, to ensure compatibility with existing enclosure designs and thermal management strategies for high-frequency environments up to 1GHz.

Part Context

This resistor belongs to Bourns Inc.'s Chassis Mount Resistors family, which provides solutions for demanding power electronics. The CHF series is engineered for stability in RF and high-frequency contexts. As a chassis-mount device, it offers superior heat dissipation compared to surface-mount alternatives, making it suitable for industrial and communication infrastructure where reliable power handling is critical.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Due to the specific 12.5 Ohm resistance, 800W power rating, and RF-specific construction, direct replacements must be sourced from official Bourns catalogs or authorized distributors. Verify that any alternative component matches the flange mounting style and tab lead configuration to maintain mechanical integrity.
