CF14JB56R0

Overview

The CF14JB56R0 is a fixed axial leaded resistor manufactured by Stackpole Electronics Inc. It utilizes carbon film technology with a nominal resistance of 56 Ohms and a tolerance of ±5%. The component is rated for 0.25W (1/4W) power dissipation and operates within a temperature range of -55°C to +155°C. It features a tubular package with dimensions of approximately 2.3mm diameter by 6mm length, designed for through-hole mounting.

Feature Summary

• Carbon film composition ensures non-inductive characteristics suitable for general circuit applications.
• Flame-retardant coating provides safety compliance for standard electronic assemblies.
• Axial leaded construction facilitates reliable through-hole PCB mounting.

Applications

• General purpose electronic circuits
• Signal conditioning networks
• Current limiting applications

Procurement Notes

Verify the specific suffix 'JB' against official Stackpole documentation to confirm tolerance and series alignment, as generic listings may conflate it with similar 'JT' or 'JA' variants. Ensure the requested quantity matches available packaging options such as bulk or tape-and-reel formats specified in the manufacturer's current catalog. Cross-reference the RoHS status and environmental compliance data directly from the datasheet prior to finalizing procurement orders.

Selection Notes

Select this component when a 56 Ohm resistance value with ±5% tolerance is required for low-power signal paths. The 1/4W rating suits standard voltage levels up to 350V. Consider the -55°C to +155°C operating range for environments with moderate thermal fluctuations. Verify that the axial lead spacing fits the target PCB layout constraints before integration.

Part Context

This part belongs to the CF series of carbon film resistors from Stackpole Electronics. It shares the physical form factor and material composition with other values in the lineup, differing primarily in resistance value and tolerance designation. The CF series is widely used in consumer electronics and industrial control boards requiring cost-effective, reliable passive components.

Replacement Considerations

Compatible substitutes include CF14JT56R0 and CFM14JA56R0, provided the application tolerates the respective tolerance differences associated with the 'JT' and 'JA' suffixes. Verify that alternative manufacturers offer equivalent 56 Ohm, 1/4W axial carbon film resistors with matching dimensional constraints and thermal ratings.
