CF12JB91K0

Overview

The CF12JB91K0 is a carbon film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 91 kOhms with a tolerance of ±5%. The component has a power rating of 0.5W (1/2W) and operates within a temperature range of -55°C to +155°C. Its physical dimensions are 2.70mm in diameter and 8.50mm in length. The device carries a safety flame-retardant coating and complies with RoHS3 standards.

Feature Summary

• Features a safety flame-retardant coating for enhanced operational security.
• Utilizes carbon film technology for stable resistive performance.
• Designed for general-purpose PCB mounting applications.

Applications

• General purpose electronic circuitry
• PCB mounting assemblies
• Signal conditioning networks

Procurement Notes

Verify the specific packaging configuration, as the CF12JB91K0 designation typically corresponds to bulk packaging, whereas suffix variations like JT indicate reel packaging. Confirm the manufacturer part number against official Stackpole documentation to ensure correct tolerance and power rating alignment before procurement.

Selection Notes

Select this component when a 91 kOhm resistance with 5% tolerance is required for axial leaded applications. Ensure the design accommodates the 0.5W power dissipation and the specified operating temperature range of -55°C to +155°C. Verify that the axial form factor fits the target PCB layout constraints.

Part Context

This resistor belongs to the CF series of carbon film components from Stackpole Electronics. It shares the same electrical specifications as the CF12JA91K0 and CF12JT91K0 variants, differing primarily in packaging type such as ammo pack or reel. The series is characterized by its standard axial leaded construction suitable for general electronics manufacturing.

Replacement Considerations

CF12JA91K0 and CF12JT91K0 are direct functional equivalents within the same series, offering identical electrical characteristics but potentially different packaging formats.
