CF14JB220K

Overview

The CF14JB220K is a carbon film through-hole resistor manufactured by SEI Stackpole. It features a resistance value of 220 kOhms with a tolerance of ±2%. The component has a power rating of 250 mW (1/4 W) and utilizes an axial leaded package for PCB mounting. It operates within a temperature range of -55°C to +155°C and carries RoHS compliance.

Feature Summary

• Utilizes carbon film technology for stable resistive performance
• Offers tight ±2% tolerance for precision circuit applications
• Designed for general purpose through-hole PCB mounting

Applications

• General purpose electronic circuits
• Precision signal conditioning networks
• Voltage divider configurations

Procurement Notes

Verify the specific suffix 'JB' confirms the 2% tolerance requirement, as standard variants often carry 5% tolerance. Confirm packaging availability matches production needs, as bulk or reel options may vary. Ensure the manufacturer designation aligns with current SEI Stackpole branding for accurate sourcing and documentation.

Selection Notes

Select this component when a 220 kOhm resistance value with higher precision than standard 5% tolerances is required. The 1/4 W power rating suits low-power signal processing tasks. Verify that the axial lead form factor fits the target printed circuit board layout constraints.

Part Context

This part belongs to the CF series of carbon film resistors from SEI Stackpole. The series provides reliable performance for general electronics. The CF14JB220K specifically denotes the 2% tolerance variant within the 1/4 W axial package family, distinguishing it from the more common 5% tolerance models.

Replacement Considerations

CF14JT220K offers identical electrical specifications except for a wider ±5% tolerance. CF14GT220K provides the same 220 kOhm value but with a tighter ±2% tolerance and potentially different manufacturing standards.
