CF18JB47K0

Overview

The CF18JB47K0 is a carbon film through-hole resistor manufactured by SEI Stackpole Electronics Inc. It belongs to the CF series and features an axial leaded package designed for PCB mounting. The component provides a nominal resistance of 47 kOhms with a tolerance of ±5%. It has a power rating of 125 mW (1/8 W) and operates within a temperature range of -55°C to +155°C. The device utilizes a carbon film technology suitable for general-purpose commercial and industrial applications.

Feature Summary

• Carbon film construction for stable resistive performance
• Axial leaded format compatible with standard PCB mounting
• Flame retardant coating for enhanced safety

Applications

• General purpose commercial electronics
• Industrial control circuitry
• Signal conditioning networks

Procurement Notes

Verify the specific suffix 'JB' against official datasheets to confirm tolerance and marking specifications, as variations exist within the CF series. Ensure the ordering quantity aligns with manufacturer packaging standards, typically available in bulk reels or cut tape formats. Cross-reference the manufacturer part number with distributor listings to confirm current availability and compliance status.

Selection Notes

Select this component when a 47 kOhm resistance value with 5% tolerance is required for low-power circuits. The 1/8 W power rating suits applications with minimal current draw. Consider the axial package size constraints and operating temperature limits relative to the target environment. Verify compatibility with automated insertion equipment if high-volume production is planned.

Part Context

This resistor is part of the broader CF series from SEI Stackpole, which offers various resistance values and power ratings. The CF18 designation indicates the 1/8 W power class within the axial carbon film lineup. Similar parts include CF18JT47K0 and CF18JA47K0, differing primarily in tolerance codes and packaging options.

Replacement Considerations

Direct substitutes include CF18JT47K0 and CF18JA47K0 from the same manufacturer. Other brands offering 47 kOhm, 1/8 W, 5% axial carbon film resistors may serve as functional equivalents, provided physical dimensions and voltage ratings are verified.
