CTTF0402F-0N8B

Fixed Inductors Overview

The CTTF0402F-0N8B is a fixed thin film inductor from Central Technologies, housed in a 0402 surface-mount package. It features an inductance of 0.8 nH with a tolerance of ±0.1 nH (suffix B). The component has a maximum DC resistance of 100 mΩ and a rated current of 700 mA. It operates within a temperature range of -55°C to +155°C and complies with RoHS standards.

Fixed Inductors Feature Summary

• Unshielded thin film construction for high-frequency stability
• Ultra-low inductance value suitable for RF matching networks
• Precision tolerance of ±0.1 nH for accurate circuit tuning

Fixed Inductors Applications

• RF impedance matching circuits
• High-frequency signal filtering
• Broadband amplifier biasing networks

Fixed Inductors Procurement Notes

Verify the suffix 'B' confirms the ±0.1 nH tolerance specification required for precision applications. Ensure the 0402 footprint matches the PCB layout constraints. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Check that the 700 mA current rating meets the operational requirements of the target circuit without saturation.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance values below 1 nH are necessary for RF designs. The thin film technology offers better stability compared to wire-wound alternatives at high frequencies. Consider the 0402 package size for space-constrained layouts. Evaluate the 100 mΩ DC resistance impact on series loss in low-impedance paths.

Fixed Inductors Part Context

This part belongs to the CTTF0402F series of thin film chip inductors from Central Technologies. The series covers a wide range of inductances from 0.2 nH to 33 nH. Different suffixes indicate varying tolerances, such as C for ±0.2 nH or S for ±0.3 nH. The 0N8B variant specifically targets applications requiring the lowest end of the inductance spectrum with tight precision.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0.8 nH ±0.1 nH inductors in 0402 packages from manufacturers like Murata or TDK. Verify that alternative parts match the 100 mΩ max DC resistance and 700 mA current rating. Ensure the replacement maintains the unshielded characteristic to preserve Q-factor performance at GHz frequencies.
