CTTF0402F-2N7B

Overview

The CTTF0402F-2N7B is a fixed thin film inductor from Central Technologies, designed for surface mount applications. It features an inductance of 2.7 nH with a tolerance of ±0.1 nH (code B). The component operates within a temperature range of -40 °C to 85 °C and has a maximum DC resistance of 300 mΩ. It supports a maximum rated current of 440 mA and achieves a self-resonant frequency of 6000 MHz. The unit is RoHS compliant and housed in a standard 0402 package.

Feature Summary

• Utilizes unshielded thin film technology for consistent RF performance
• Offers high precision tolerance options including ±0.1 nH
• Supports high-frequency operation up to 6000 MHz
• Complies with RoHS standards for lead-free manufacturing

Applications

• RF circuits
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify the specific tolerance suffix 'B' corresponds to ±0.1 nH accuracy when ordering. Confirm that the 0402 footprint matches the target PCB layout dimensions. Ensure the operating environment stays within the specified -40 °C to 85 °C range to maintain electrical stability. Check for RoHS compliance documentation if required by regulatory standards. Validate the 440 mA current rating against circuit load requirements.

Selection Notes

Select this component for applications requiring precise low-nanohenry values in compact spaces. The thin film construction provides better stability compared to wire-wound alternatives at high frequencies. Consider the 300 mΩ DC resistance impact on series impedance. Evaluate the 6000 MHz self-resonant frequency to ensure it exceeds the operational bandwidth. Compare with other CTTF0402F variants if different tolerances or inductance values are needed.

Part Context

This part belongs to the CTTF0402F series, which covers inductance values from 0.2 nH to 33 nH. The series offers various tolerance codes such as F, G, H, and J for broader ranges, while code B provides the tightest precision. All parts share the same 0402 SMD form factor and general purpose classification.

Replacement Considerations

Compatible substitutes include other CTTF0402F variants with similar inductance, such as CTTF0402F-2N7G or CTTF0402F-2N7J, provided the tolerance difference is acceptable. Cross-brand equivalents must match the 0402 package, 2.7 nH value, and RF application requirements.
