Overview
The CTTF0402F-33NJ is a general-purpose surface-mount inductor manufactured by Central Technologies. It features a nominal inductance of 0.033 µH with a tolerance of ±5%. The component operates within a temperature range of -40 °C to 85 °C and has a maximum rated current of 0.19 A. Key electrical specifications include a DC resistance of 1.6 Ω, a minimum quality factor of 13 at the nominal inductance, and a self-resonant frequency of 6000 MHz. It is RoHS compliant and lead-free.
Feature Summary
- Designed for RF applications as a general-purpose inductor
- Surface mount construction in a standard 0402 package
- Compliant with RoHS standards and lead-free manufacturing
Applications
- RF circuits
- General purpose inductive filtering
- High-frequency signal processing
Procurement Notes
Verify the specific tolerance suffix 'J' corresponds to the required ±5% accuracy for your design. Confirm that the 0402 footprint matches your PCB layout constraints. Ensure the operating temperature range up to 85 °C meets your environmental requirements. Check that the maximum rated current of 0.19 A is sufficient for your circuit's peak load conditions.
Selection Notes
Select this component when a low-inductance value near 33 nH is required in a compact SMD form factor. Consider the 1.6 Ω DC resistance impact on series resistance. Evaluate the 6000 MHz self-resonant frequency to ensure it exceeds your operational frequency. Compare against other tolerances if tighter precision is needed.
Part Context
This part belongs to the CTTF0402F series from Central Technologies, which offers various inductance values ranging from 0.2 nH to 33 nH in the 0402 package. The series provides options for different tolerance codes (B, C, S, F, G, H, J) to suit varying application precision needs. It is designed for high-frequency applications requiring small physical dimensions.
Replacement Considerations
Other parts in the CTTF0402F series with the same 33 nH inductance but different tolerance codes (e.g., CTTF0402F-33NG for ±2%) may be suitable if tighter tolerance is acceptable. Cross-reference with other manufacturers offering 0402 RF inductors with similar electrical parameters.
