CTTF0402F-20N8G

Overview

The CTTF0402F-20N8G is a fixed thin film inductor from Central Technologies, housed in a 0402 surface-mount package. It features a nominal inductance of 20.8 nH with a tolerance of ±5%. The component has a maximum DC resistance of 2.6 Ω and a self-resonant frequency of 6 GHz. It supports a maximum rated current of 90 mA and operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Thin film construction for stable RF performance
• Unshielded design suitable for general-purpose applications
• RoHS compliant and lead-free manufacturing

Applications

• RF circuits
• General purpose inductor applications

Procurement Notes

Verify the specific suffix 'G' corresponds to the required ±5% tolerance when ordering, as other suffixes indicate different tolerances. Confirm the 0402 footprint dimensions match the PCB layout. Ensure the 90 mA current rating meets the circuit requirements. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this part for low-inductance RF applications requiring high self-resonant frequency. Consider the 2.6 Ω DC resistance impact on signal loss. Evaluate the 90 mA current limit against peak load conditions. Compare with other CTTF0402F variants for alternative inductance values or tighter tolerance options if needed.

Part Context

This component belongs to the CTTF0402F series, which offers various inductance values ranging from 0.2 nH to 33 nH in the 0402 package. The series provides multiple tolerance options including ±1%, ±2%, ±3%, and ±5%. All parts share similar physical dimensions and operational characteristics typical of thin film chip inductors.

Replacement Considerations

Direct substitutes include other CTTF0402F variants with identical 20.8 nH inductance but different tolerances, such as CTTF0402F-20N8J (±5%) or CTTF0402F-20N8G. Cross-brand replacements require matching 0402 footprint, 20.8 nH value, 6 GHz SRF, and 90 mA current rating.
