Overview
The CT0402CSF-19NG is a fixed wire-wound chip inductor manufactured by Central Technologies. It features a ceramic core and is housed in a standard 0402 surface-mount package. The component provides an inductance of 19 nH with a tolerance code 'N' indicating ±5%. It has a maximum DC resistance of 0.35 Ω and a minimum quality factor of 28 at the test frequency. The device is rated for operation between -40 °C and +125 °C, complies with RoHS standards, and contains no lead.
Feature Summary
- Utilizes a wire-wound construction on a ceramic core for stable performance
- Designed for high-current applications within a compact 0402 footprint
- Compliant with RoHS directives and free from lead content
Applications
- High current inductor circuits
- General purpose RF filtering
- Signal conditioning in mobile devices
Procurement Notes
Verify the specific tolerance suffix when ordering, as the 'N' code denotes ±5% inductance variance. Confirm that the 0402 package dimensions align with the target PCB layout constraints. Ensure the operating temperature range of -40 °C to +125 °C meets the environmental requirements of the final assembly. Cross-reference the datasheet for precise DC resistance values to validate power loss calculations.
Selection Notes
Select this component for designs requiring low-profile surface-mount inductors with moderate inductance values. The 0402 case size offers space efficiency for dense circuit boards. Consider the 0.35 Ω DC resistance limit for current handling capabilities. The ceramic core material supports stability across the specified industrial temperature range. Evaluate the minimum Q factor of 28 for signal integrity needs in the target frequency band.
Part Context
This part belongs to the CT0402CSF series of wire-wound chip inductors produced by Central Technologies. The series spans various inductance values from 1.6 nH to 390 nH, all sharing the same 0402 physical form factor. The CSF designation indicates a ceramic-core construction suitable for general-purpose applications. This specific model represents a mid-range inductance option within the available product lineup.
Replacement Considerations
Direct substitutes must match the 0402 package, 19 nH nominal value, and ceramic core type. Verify equivalent DC resistance and current ratings before substitution. Check for compatible tolerance codes to ensure circuit performance consistency. Review thermal specifications to confirm operational safety under identical load conditions.
