CTTF0402F-3N9B

Overview

The CTTF0402F-3N9B is a fixed thin film chip inductor manufactured by Central Technologies, designed for surface-mount applications. It features an inductance of 3.9 nH with a tolerance of ±0.1 nH (Code B). The component operates within a temperature range of -55°C to +125°C and has a maximum DC resistance of 500 mΩ. It supports a maximum current of 340 mA and utilizes a standard 0402 (1005 metric) package footprint.

Feature Summary

• Thin film construction for high precision
• Unshielded design suitable for low-inductance RF circuits
• Compliant with RoHS standards

Applications

• RF matching networks
• High-frequency signal processing
• Portable communication devices

Procurement Notes

Verify the specific suffix code (e.g., B for ±0.1nH) against the required tolerance. Confirm the operating temperature range requirements match the component's rated limits. Ensure the PCB land pattern corresponds to the 0402 package dimensions. Check for any specific handling instructions regarding unshielded components.

Selection Notes

Select this part when precise low-nanohenry inductance is critical for RF tuning. The thin film technology offers stability compared to wire-wound alternatives. Consider the unshielded nature for potential EMI implications in dense layouts. Verify that the 340 mA current rating meets the circuit's peak load demands.

Part Context

This component belongs to the CTTF0402F series of thin film chip inductors from Central Technologies. The series covers a wide range of low inductance values, typically from 0.2 nH to 33 nH. These inductors are engineered for high-frequency applications where size and precision are paramount.

Replacement Considerations

Direct substitutes include other 0402 thin film inductors with 3.9 nH nominal value and ±0.1 nH tolerance. Ensure equivalent DC resistance and current ratings. Cross-reference with similar series from other manufacturers if supply constraints exist.
