Overview
The CT0402CSF-33NJ is a general purpose inductor from Central Technologies, designed for surface-mount applications. It features a nominal inductance of 0.033 µH with a tolerance of ±5%. The component utilizes a ceramic core and exhibits a DC resistance of 0.46 Ω. It supports a maximum rated current of 0.31 A and achieves a minimum quality factor of 26 at the nominal inductance. The self-resonant frequency is specified at 2200 MHz. The device operates within a temperature range of -40 °C to 125 °C and complies with RoHS standards.
Feature Summary
- Surface-mount chip inductor with ceramic core construction
- High self-resonant frequency suitable for RF applications
- RoHS compliant manufacturing process
Applications
- RF inductor circuits
- General purpose electronic filtering
- Signal processing components
Procurement Notes
Verify RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Confirm that the specific ordering suffix matches the required tolerance code. Ensure storage conditions align with standard surface-mount component handling guidelines to maintain performance integrity prior to assembly.
Selection Notes
Select this component when a low-inductance value near 33 nH is required in a compact 0402 footprint. Consider the 0.31 A current rating and 0.46 Ω DC resistance for power budget calculations. The ceramic core offers stability compared to air cores, while the high SRF ensures minimal parasitic effects in high-frequency designs.
Part Context
This part belongs to the CT0402CS series of wire-wound chip inductors manufactured by Central Technologies. The series provides various inductance values ranging from 1 nH to 68 nH in the 0402 package. The 'CS' designation indicates a ceramic core, distinguishing it from other core materials in the product line.
Replacement Considerations
Cross-reference with other 0402 ceramic-core inductors offering 33 nH ±5% tolerance. Verify compatibility regarding DC resistance, current rating, and self-resonant frequency before substitution.
