Overview
The CT0402CSF-11NG is a fixed wire-wound inductor from Central Technologies, designed for surface-mount applications. It features an inductance of 11 nH with a tolerance of ±2%. The component has a maximum DC resistance of 0.12 Ohms and a self-resonant frequency of 250 MHz. It supports a maximum rated current of 0.64 A and achieves a quality factor of 24 at the nominal inductance. The device utilizes a ceramic core and operates within a temperature range of -55 °C to 125 °C. It is housed in a standard 0402 rectangular package.
Feature Summary
- Wire-wound construction on a ceramic core for stable RF performance
- Automotive-grade reliability qualification
- High Q-factor design optimized for high-frequency signal integrity
Applications
- RF matching networks
- Impedance matching circuits
- Filtering applications in communication devices
Procurement Notes
Verify that the ordering suffix 'N' confirms RoHS compliance and lead-free termination specifications. Confirm the 'G' suffix indicates tape-and-reel packaging format. Ensure the specific tolerance code matches the required circuit precision. Cross-reference the manufacturer datasheet to validate the automotive grade designation against project requirements.
Selection Notes
Select this component when a low-inductance value near 11 nH is required for high-frequency filtering or impedance matching. The 0402 footprint suits space-constrained designs. Consider the 0.64 A current rating for power handling needs. The ceramic core provides thermal stability suitable for demanding environments compared to air-core alternatives.
Part Context
This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies. The series offers various inductance values within the 0402 package size. The CSF designation typically denotes ceramic-core wire-wound construction with specific automotive and high-reliability characteristics distinct from general-purpose multilayer variants.
Replacement Considerations
Direct substitutes include other 11 nH ±2% inductors in the 0402 package with comparable DCR and SRF. Verify that alternative components meet the same automotive qualification standards and RoHS compliance requirements.
