CF12JB2M40

Overview

The CF12JB2M40 is a carbon film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 2.4 MOhms 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 0.106 inches in diameter by 0.335 inches in length (2.70mm x 8.50mm). The device includes a flame retardant coating for safety compliance.

Feature Summary

• Features a flame retardant coating designed for enhanced safety applications
• Utilizes carbon film technology for stable resistive performance
• Constructed with an axial leaded package suitable for through-hole mounting

Applications

• General purpose electronic circuitry requiring high resistance values
• Industrial equipment utilizing through-hole PCB assembly
• Consumer electronics components demanding safety compliance

Procurement Notes

Verify the specific suffix designation against official Stackpole documentation to confirm the exact tolerance and temperature coefficient specifications. Ensure that the required flame retardant certification aligns with your project's safety standards. Confirm availability status directly with authorized distributors as stock levels fluctuate. Cross-reference the datasheet for any updates regarding RoHS compliance or environmental regulations relevant to your region.

Selection Notes

Select this component when a high-value resistance is needed in a standard axial form factor. The carbon film composition offers a balance of cost and performance for non-critical applications. Consider the ±5% tolerance if tighter precision is not required. The wide operating temperature range supports use in varied environmental conditions. Ensure the physical size fits within the designated board space constraints.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. It shares the general axial package style with other variants in the lineup but differs in resistance value and specific coating requirements. The CF series is widely used in general-purpose electronics, providing a reliable solution for basic resistive functions in through-hole designs.

Replacement Considerations

CF12JA2M40 is a parameter-equivalent alternative within the same manufacturer lineup.
