CTTF0402F-2N2C

Overview

The CTTF0402F-2N2C is a fixed thin film inductor manufactured by Central Technologies, designed for surface mount applications. It features an unshielded construction within a standard 0402 (1005 Metric) package footprint. The component provides a nominal inductance of 2.2 nH with a tolerance of ±0.2 nH. It supports a maximum DC current rating of 440 mA and maintains a maximum DC resistance of 300 mOhm. The self-resonant frequency is specified at 13 GHz when measured at 500 MHz.

Feature Summary

• Utilizes thin film technology for high-frequency stability
• Unshielded design minimizes parasitic effects
• Compact 0402 surface mount form factor

Applications

• RF circuit impedance matching networks
• Microwave signal processing stages
• High-speed data transmission line termination

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's official datasheet to confirm the exact tolerance and packaging specifications. Ensure that the required operating temperature range aligns with the component's rated limits. Confirm that the 0402 package dimensions are compatible with the target PCB land pattern and soldering process capabilities before finalizing procurement orders.

Selection Notes

Select this component for circuits requiring precise low-nanohenry inductance values where high self-resonant frequency is critical. The 440 mA current rating suits moderate power RF applications. Consider the unshielded nature for layout sensitivity. Compare against similar thin film inductors if tighter tolerances or shielded variants are necessary for specific electromagnetic interference constraints.

Part Context

This part belongs to the CTTF0402F series of thin film chip inductors from Central Technologies. The series offers various inductance values optimized for RF and microwave frequencies. The 0402 size allows for dense board layouts. Thin film construction generally provides better Q-factor and stability compared to wire-wound alternatives at these low inductance levels.

Replacement Considerations

Cross-reference with other manufacturers offering 2.2 nH ±0.2 nH thin film inductors in 0402 packages. Verify that substitute parts match the 300 mOhm DCR and 440 mA current ratings. Ensure the replacement maintains the 13 GHz self-resonant frequency specification to avoid performance degradation in high-frequency designs.
