Overview
The CT0402CSF-12NG is a surface-mount wire-wound chip inductor manufactured by Central Technologies. It features a ceramic core and operates within a temperature range of -40 °C to 125 °C. The component has a nominal inductance of 0.012 µH with a tolerance of ±5%. It exhibits a maximum DC resistance of 0.135 Ω, a minimum quality factor of 28 at the test frequency, and a maximum rated current of 0.7 A.
Feature Summary
- Utilizes a wire-wound construction on a ceramic core for stable performance
- Designed for high-current applications within the general-purpose category
- Compliant with RoHS standards and lead-free manufacturing requirements
Applications
- High current inductor circuits
- General purpose RF applications
- Communication devices
- Consumer products
Procurement Notes
Verify the specific tolerance code suffix when ordering, as the base part number requires designation for accuracy levels such as J for ±5%. Confirm that the ceramic core construction aligns with the thermal and current requirements of the target circuit design. Ensure compliance with RoHS directives if required by the end product specifications.
Selection Notes
Select this component for applications requiring a compact 0402 footprint with moderate current handling capabilities up to 0.7 A. The low DC resistance supports efficient power transfer, while the ceramic core provides stability. Consider the self-resonant characteristics inherent to wire-wound designs when integrating into high-frequency signal paths.
Part Context
This inductor belongs to the CT0402CSF series from Central Technologies, which offers various inductance values ranging from 1.6 nH to 390 nH in the 0402 package. The series is characterized by wire-wound technology on ceramic cores, providing a balance between size constraints and electrical performance for surface-mount assembly processes.
Replacement Considerations
Direct substitutes include other CT0402CSF variants with matching inductance and tolerance codes. Cross-manufacturer replacements must match the 0402 footprint, 0.012 µH value, 0.7 A current rating, and 0.135 Ω DCR limits.
