Procurement Notes

Verify the specific manufacturer datasheet for the CF18JB180K to confirm compliance with RoHS directives and other regional regulatory standards. Ensure that the axial lead dimensions match the target PCB footprint requirements. Cross-reference the part number with official distributor catalogs to validate authenticity and traceability before finalizing procurement decisions.

Selection Notes

Select this component when a 1-watt power rating and 180 kOhm resistance are required in a through-hole configuration. Consider the ±5% tolerance and carbon composition material properties for applications where cost-effectiveness and high surge capability are prioritized over tight precision or low noise specifications typical of metal film alternatives.

Part Context

This resistor belongs to Stackpole Electronics' series of axial leaded components. The 'CF' designation typically indicates carbon film or composition construction, while 'J' denotes the ±5% tolerance class. The '1W' power handling capacity distinguishes it from lower-power surface mount or smaller axial variants, making it suitable for higher energy dissipation scenarios in legacy or rugged designs.

Replacement Considerations

Compatible substitutes include other 180 kOhm, 1W, ±5% axial resistors from manufacturers such as Yageo or Vishay. Verify that replacement parts maintain identical physical dimensions for PCB compatibility and match the original component's voltage and temperature ratings to ensure circuit integrity.

FAQ
