CF12JB180R

Overview

The CF12JB180R is a carbon film axial through-hole resistor manufactured by Stackpole Electronics Inc. It features a resistance value of 180 Ohms 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. It exhibits a temperature coefficient of ±400ppm/°C. The physical dimensions are 0.106 inches in diameter by 0.335 inches in length (2.70mm x 8.50mm). The device is RoHS compliant and meets REACH standards.

Feature Summary

• Constructed with carbon film composition for general-purpose resistive applications.
• Features flame-retardant coating for enhanced safety compliance.
• Designed for high-temperature stability across a wide operational range.

Applications

• Commercial electronic equipment
• Industrial control circuits
• General-purpose PCB mounting

Procurement Notes

Verify the specific suffix 'JB' against official Stackpole documentation to confirm it denotes the standard ±5% tolerance variant, as datasheets often group this series under generic CF/CFM headers. Ensure the ordering part number matches the exact electrical specifications required for your design, particularly the 180 Ohm value and 1/2W power rating, before finalizing procurement.

Selection Notes

Select this component when a standard carbon film resistor with ±5% tolerance is required for general-purpose circuits. It serves as an alternative to the CF12JT180R if the specific 'JB' designation is mandated by the bill of materials. Consider the axial lead form factor and 1/2W power dissipation capability relative to the available board space and thermal environment.

Part Context

This resistor belongs to the CF series of carbon film components from Stackpole Electronics. The series is characterized by its reliability in commercial and industrial environments. The CF12JB180R shares the same physical footprint and core electrical characteristics as other variants in the 1/2W axial category, differing primarily in manufacturing lot or specific supplier coding conventions.

Replacement Considerations

CF12JT180R is a parameter-equivalent substitute within the same manufacturer's lineup. Other axial carbon film resistors with identical 180 Ohm, 1/2W, and ±5% specifications may also serve as functional replacements depending on mechanical constraints.
