Overview
The CT0402CSF-23NG is a wire-wound chip inductor from Central Technologies, housed in a 0402 surface-mount package. It features a ceramic core and offers a nominal inductance of 23 nH with a tolerance of ±2%. The component has a maximum rated current of 0.7 A and a DC resistance of 0.135 Ω. It operates within a temperature range of -40°C to +125°C and meets RoHS compliance standards.
Feature Summary
- Wire-wound construction on a ceramic core for stable performance
- High current handling capability suitable for power applications
- Compact 0402 surface-mount footprint for space-constrained designs
Applications
- High current inductor circuits
- General purpose filtering
- RF circuit impedance matching
Procurement Notes
Verify the specific tolerance suffix when ordering, as the base part number may require a designated code for precision variants. Confirm that the 0402 package dimensions align with your PCB layout requirements. Ensure the operating environment stays within the specified -40°C to +125°C range to maintain component integrity and electrical stability during operation.
Selection Notes
Select this component for applications requiring high current handling in a small form factor. The ceramic core provides thermal stability compared to other core materials. Consider the low DC resistance for efficiency in power paths. Verify that the 23 nH value fits the target frequency response needs of the specific circuit design without causing unwanted resonance issues.
Part Context
This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies. The series covers a wide range of inductance values from 1.6 nH to 390 nH in the 0402 package. These components are designed for general-purpose use, balancing size, current capacity, and electrical performance for modern electronic assemblies.
Replacement Considerations
Direct substitutes include other 0402 wire-wound inductors with 23 nH nominal value and similar current ratings. Check datasheets for equivalent DC resistance and saturation current specifications to ensure circuit compatibility.
