CTTF0402F-5N9B

Overview

The CTTF0402F-5N9B is a fixed thin film inductor manufactured by Central Technologies, designed for surface mount applications. It features an inductance of 5.9 nH with a tolerance of ±0.1 nH. The component operates within a temperature range of -55 °C to +125 °C and has a maximum DC resistance of 700 mΩ. It supports a rated current of 280 mA and utilizes a 0402 (1005 Metric) package size.

Feature Summary

• Unshielded thin film construction for high-frequency stability
• Precision inductance tolerance of ±0.1 nH
• Surface mount design compatible with automated assembly

Applications

• RF circuits requiring precise low-inductance values
• High-frequency signal processing systems
• Impedance matching networks in communication devices

Procurement Notes

Verify the specific suffix 'B' corresponds to the required ±0.1 nH tolerance when ordering, as other suffixes indicate different tolerances. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure storage conditions align with moisture sensitivity levels specified in the official datasheet to maintain component integrity prior to soldering.

Selection Notes

Select this component for applications demanding tight inductance control at very low nanohenry values. The unshielded design may require layout considerations regarding magnetic coupling with nearby components. Evaluate the 280 mA current rating against peak circuit loads to prevent saturation or thermal issues. The 0402 footprint offers space efficiency for dense PCB layouts.

Part Context

This part belongs to the CTTF0402F series of thin film chip inductors from Central Technologies. The series provides various inductance values ranging from 0.2 nH to 33 nH in a compact 0402 package. Different suffixes denote varying tolerance codes, allowing designers to choose precision levels suitable for specific RF and general-purpose applications.

Replacement Considerations

Compatible substitutes include other 0402 thin film inductors with 5.9 nH nominal value and ±0.1 nH tolerance. Verify that replacement parts match the 700 mΩ max DC resistance and 280 mA current rating. Ensure the alternative component maintains similar self-resonant frequency characteristics for high-frequency performance equivalence.
