Overview
The CT0402CSF-1N0K is a fixed wire-wound chip inductor from Central Technologies, housed in a standard 0402 surface-mount package. It features a ceramic core and offers a nominal inductance of 1 nH with a tolerance of ±5%. The component exhibits a maximum DC resistance of 40 mΩ and supports a rated current of 0.38 A. Designed for RF applications, it achieves a minimum quality factor of 16 at the nominal inductance and operates within a temperature range of -40 °C to +85 °C.
Feature Summary
- Utilizes a wire-wound construction on a ceramic core for stable RF performance
- Designed for high-frequency general-purpose inductive applications
- Compliant with RoHS standards for lead-free manufacturing
Applications
- RF circuit impedance matching networks
- High-frequency signal filtering stages
- General-purpose inductive components in compact SMD designs
Procurement Notes
Verify the specific suffix 'K' corresponds to the required ±5% tolerance when ordering. Confirm that the 0402 footprint aligns with the target PCB layout. Ensure the 0.38 A current rating meets the operational requirements of the intended circuit application.
Selection Notes
Select this component for applications requiring precise low-nanohenry inductance in a minimal footprint. The ceramic core provides stability suitable for RF environments. Consider the 40 mΩ DC resistance impact on series circuits. Verify thermal limits against the operating environment constraints.
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 nH to 120 nH within the same 0402 package form factor, allowing for consistent assembly processes across different frequency requirements.
Replacement Considerations
Direct substitutes include other 0402 wire-wound inductors with 1 nH nominal value and ±5% tolerance. Verify compatibility regarding Q-factor, self-resonant frequency, and physical dimensions before substitution.
