Overview

The CTTF0402F-5N6B is a general purpose surface mount inductor manufactured by Central Technologies. It features a nominal inductance of 0.0056 µH with a tight tolerance of ±0.1 nH (Code B). The component operates within a temperature range of -40 °C to 85 °C and has a maximum rated current of 0.3 A. Key electrical specifications include a DC resistance of 0.7 Ω, a minimum quality factor of 13 at the nominal inductance, and a self-resolving frequency of 6000 MHz. It is RoHS compliant and contains no lead.

Feature Summary

• Designed for RF applications as a general purpose inductor
• Offers extremely tight inductance tolerance for precision circuits
• Supports high-frequency operation up to 6000 MHz
• Compliant with RoHS standards for environmental safety

Applications

• RF Inductor circuits
• High-frequency signal processing
• Precision impedance matching networks

Procurement Notes

Verify the specific tolerance code suffix 'B' corresponds to the required ±0.1 nH accuracy during ordering, as this series offers multiple tolerance options. Confirm that the operating environment remains within the specified -40 °C to 85 °C range to ensure performance stability. Ensure the application current does not exceed the 0.3 A maximum rating to prevent thermal issues or inductance drift.

Selection Notes

Select this component when precise low-value inductance is critical for RF circuit design. The ±0.1 nH tolerance provides superior consistency compared to standard general-purpose variants. Consider the 6000 MHz self-resonant frequency limit to ensure suitability for the target signal frequencies. Verify that the 0.3 A current rating aligns with the peak currents expected in the specific application circuit.

Part Context

This part belongs to the CTTF0402F series from Central Technologies, which covers inductances from 0.2 nH to 33 nH in a 0402 package. The series is characterized by thin-film technology, offering high Q factors and stable performance. It serves as a specialized solution for compact electronic designs requiring accurate RF filtering or matching components.

Replacement Considerations

Compatible substitutes within the same series include CTTF0402F-5N6G (±2%), CTTF0402F-5N6J (±5%), and CTTF0402F-5N6H (±3%). These alternatives offer looser tolerances but maintain identical electrical characteristics such as inductance value, package size, and frequency response.
