CF14JB7R50

Overview

The CF14JB7R50 is a fixed axial leaded resistor manufactured by Stackpole Electronics Inc. It utilizes carbon film technology to provide a nominal resistance of 7.5 Ohms with a tolerance of ±5%. The component is rated for a power dissipation of 0.25 Watts (1/4 W) and features a tubular package design. It operates within a temperature range of -55°C to +155°C, ensuring stability across various environmental conditions.

Feature Summary

• Carbon film construction provides general-purpose resistive performance suitable for commercial and industrial applications.
• Standard flame retardant coatings are applied to the exterior for enhanced safety and compliance.
• Axial leaded configuration facilitates through-hole mounting on printed circuit boards.

Applications

• General purpose current limiting in electronic circuits
• Voltage division networks requiring standard tolerance components
• Industrial control systems utilizing through-hole assembly

Procurement Notes

Verify that the specific part number matches the required resistance value and tolerance before procurement. Confirm that the axial leaded package dimensions align with the target PCB layout. Ensure that the carbon film composition meets the electrical requirements of the application environment. Check for RoHS compliance status if restricted substances are a concern for the final product assembly.

Selection Notes

Select this component when a low-cost, general-purpose resistor is required for non-critical circuit paths. The carbon film technology offers a balance between cost and performance for standard applications. Consider the axial lead form factor for manual or wave soldering processes where surface mount alternatives are not feasible. Evaluate the thermal rating against the expected operating conditions to ensure reliable long-term operation.

Part Context

This resistor belongs to the CF series of carbon film components produced by Stackpole Electronics Inc. The series is designed for broad utility in consumer electronics and industrial equipment. The CF14JB7R50 specifically addresses the need for low-value, high-current capable resistors in through-hole designs. It represents a standard offering within the manufacturer's passive component portfolio.

Replacement Considerations

Direct substitutes include other manufacturers' carbon film resistors with identical 7.5 Ohm values and 1/4W ratings. Cross-reference axial dimensions to ensure mechanical compatibility. Verify that alternative components maintain similar flame retardancy and temperature coefficient characteristics for equivalent performance.
