Overview
The CTTF0402F-18NG is a general purpose thin film chip inductor manufactured by Central Technologies. It features a nominal inductance of 0.018 µH with a tolerance of ±2%. The component operates within a temperature range of -40 °C to 100 °C and has a maximum rated current of 0.24 A. It exhibits a DC resistance of 0.7 Ω, a minimum quality factor of 8 at the nominal inductance, and an self-resonant frequency of 2200 MHz. Packaged in a standard 0402 surface-mount footprint, it is RoHS compliant.
Feature Summary
- Thin film construction for stable RF performance
- Unshielded design suitable for high-frequency applications
- RoHS compliant manufacturing process
Applications
- RF circuits
- General purpose inductive filtering
- High-frequency signal processing
Procurement Notes
Verify the specific suffix code against the manufacturer's ordering guide to ensure the correct tolerance level is selected. Confirm that the 0402 package dimensions align with the target PCB layout constraints. Ensure the operating temperature requirements fall within the specified -40 °C to 100 °C range for reliable performance in the intended application environment.
Selection Notes
Select this component when a precise 18 nH inductance value is required in a compact 0402 footprint. Consider the 0.24 A current rating and 0.7 Ω DC resistance for power handling capabilities. Evaluate the 2200 MHz self-resonant frequency to ensure suitability for the target operating frequency band without parasitic resonance issues.
Part Context
This part belongs to the CTTF0402F series of thin film chip inductors from Central Technologies. The series offers various inductance values ranging from 0.2 nH to 33 nH with different tolerance options. The 'G' suffix indicates a ±2% tolerance, while the base model provides unshielded thin film technology optimized for RF applications.
Replacement Considerations
Compatible substitutes include other 0402 thin film inductors with 18 nH nominal inductance and similar electrical characteristics. Verify that alternative parts meet the same current rating, DC resistance, and self-resonant frequency requirements to maintain circuit performance integrity.
