CTTF0402F-3N8B

Overview

The CTTF0402F-3N8B is a fixed thin film inductor manufactured by Central Technologies, designed for surface-mount applications. It features an inductance of 3.8 nH with a tolerance of ±0.1 nH (code B). The component operates within a temperature range of -55 °C to +125 °C and has a maximum DC resistance of 550 mΩ. It supports a rated current of 340 mA and achieves a self-resonant frequency of up to 5500 MHz. The device utilizes a 0402 package footprint.

Feature Summary

• Thin film construction for high-frequency stability
• Unshielded design suitable for compact layouts
• RoHS compliant manufacturing process

Applications

• RF circuits
• High-speed digital interfaces
• Impedance matching networks

Procurement Notes

Verify the specific tolerance suffix 'B' corresponds to ±0.1 nH accuracy during ordering. Confirm that the 0402 package dimensions align with PCB footprint requirements. Ensure the 340 mA current rating meets circuit load demands. Check RoHS compliance documentation if required by project standards.

Selection Notes

Select this component for applications requiring precise low-nanohenry inductance values. The thin film technology offers superior Q-factor characteristics compared to standard chip inductors. Consider the unshielded nature when designing near sensitive signal traces to minimize crosstalk risks.

Part Context

This part belongs to the CTTF0402F series from Central Technologies, which provides various inductance values ranging from 0.2 nH to 33 nH in a 0402 package. The series is engineered for RF and high-frequency applications where size and precision are critical constraints.

Replacement Considerations

Direct substitutes include other 3.8 nH ±0.1 nH thin film inductors in 0402 packages from manufacturers like Johanson Technology or Murata, provided electrical parameters match exactly.
