Overview
The CT0402CSF-30NG is a fixed wire-wound chip inductor manufactured by Central Technologies, designed for surface-mount applications. It features a nominal inductance of 30 nH with a tolerance code 'N' indicating ±5% accuracy. The component utilizes a ceramic core and offers a maximum DC resistance of 0.41 Ω. It supports a maximum rated current of 0.68 A and operates within a temperature range of -40 °C to +125 °C. The device complies with RoHS standards and is housed in a standard 0402 package.
Feature Summary
- Wire-wound construction on a ceramic core for stable RF performance
- High Q-factor capability suitable for radio frequency circuits
- RoHS compliant lead-free termination for environmental safety
Applications
- RF filter networks
- Impedance matching circuits
- General purpose inductive filtering
Procurement Notes
Verify the specific suffix 'N' corresponds to the required ±5% tolerance when ordering, as other codes denote different tolerances. Confirm that the 0402 footprint matches the target PCB layout. Ensure the operating environment remains within the specified -40 °C to +125 °C range to maintain electrical stability. Cross-reference the datasheet for precise impedance characteristics at target frequencies.
Selection Notes
Select this component for applications requiring low inductance values in compact spaces. The 0.68 A current rating suits moderate power levels. Compare against multilayer alternatives if higher self-resonant frequencies are critical. Verify that the 0.41 Ω DC resistance aligns with circuit loss requirements. Consider thermal management if continuous operation approaches the maximum current limit.
Part Context
This part belongs to the CT0402CSF series of wire-wound chip inductors from Central Technologies. The series covers a wide inductance range from 1.6 nH to 390 nH in the 0402 package. Variants differ by inductance value and tolerance suffixes such as G (±2%), J (±5%), or K (±10%). This specific model provides a 30 nH option with tight tolerance control.
