CF14JB1M20

Overview

The CF14JB1M20 is a carbon film through-hole axial resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 1.2 MOhms with a tolerance of ±5% and a power rating of 0.25W (1/4W). The component operates within a temperature range of -55°C to +155°C and has a temperature coefficient of 0/-400ppm/°C. Physical dimensions are 0.091 inches in diameter by 0.236 inches in length (2.30mm x 6.00mm). It includes a flame retardant safety coating and complies with RoHS3 standards.

Feature Summary

• Constructed with carbon film technology for stable resistive performance.
• Features a flame retardant coating designed for enhanced safety compliance.
• Supports wide operating temperatures ranging from -55°C to +155°C.

Applications

• General purpose electronic circuit design
• Industrial control systems
• Consumer electronics assemblies

Procurement Notes

Verify the specific suffix 'JB' indicates bulk packaging when ordering, as other suffixes like 'JT' denote tape and reel formats. Confirm that the 1.2 MOhm value aligns with circuit requirements, as high-value resistors may have different handling characteristics. Ensure compatibility with automated insertion equipment if using bulk quantities, as lead forming may be required for standard PCB mounting processes.

Selection Notes

Select this component for applications requiring high resistance values in a standard 1/4W axial form factor. The carbon film composition offers a cost-effective solution compared to metal film alternatives while maintaining adequate stability for general use. Consider the physical size constraints, as the 2.30mm diameter requires appropriate PCB pad spacing. Verify thermal management needs given the 155°C maximum operating limit.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. The series is characterized by its robust construction and compliance with international environmental standards including RoHS3 and REACH. It serves as a fundamental passive component in various electronic assemblies where precise resistance is less critical than cost-effectiveness and reliability.

Replacement Considerations

CFR16J1M2 by TE Connectivity Passive Product is a documented similar substitute offering comparable electrical specifications and axial packaging.
