Overview
The CT0402CSF-33NG is a fixed wire-wound chip inductor from Central Technologies, designed for surface-mount applications. It features a ceramic core and offers a nominal inductance of 0.033 µH with a tolerance of ±2%. The component operates within a temperature range of -40°C to +125°C and has a maximum rated current of 0.38 A. Its self-resonant frequency reaches 6000 MHz, and it exhibits a minimum quality factor of 13 at the nominal inductance.
Feature Summary
- Wire-wound construction on a ceramic core for stable RF performance
- High self-resonant frequency capability up to 6000 MHz
- Extended operating temperature range suitable for harsh environments
Applications
- RF circuits requiring high-frequency stability
- General purpose inductive filtering
- High-current signal processing applications
Procurement Notes
Verify the specific ordering suffix to confirm the tolerance code, as the base part number requires specification of the tolerance variant during procurement. Ensure compliance with RoHS standards by checking the component marking or datasheet documentation for lead-free certification details before finalizing purchase orders.
Selection Notes
Select this component when a compact 0402 footprint is required for high-frequency signal integrity. Consider the 0.38 A current rating and 125°C thermal limit against circuit demands. The ceramic core provides advantages over iron powder cores in terms of Q-factor and self-resonant frequency for RF designs.
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 low nanohenries to higher microhenry ranges, all sharing the same 0402 package dimensions and general structural characteristics for consistent board layout.
Replacement Considerations
Direct substitutes include other 0402 wire-wound inductors with similar 33 nH values and ±2% tolerance. Verify that alternative components match the 0.38 A current rating and 6000 MHz self-resonant frequency to maintain circuit performance without modification.
