CTTF0402F-0N4B

Fixed Inductors Overview

The CTTF0402F-0N4B is a general-purpose unshielded thin film chip inductor manufactured by Central Technologies. It features a nominal inductance of 0.4 nH with a tolerance of ±0.1 nH (Code B). The component operates within a temperature range of -40°C to +85°C and has a maximum DC resistance of 0.1 Ω. It supports a maximum rated current of 800 mA and achieves a self-resonant frequency of 6 GHz. The device is RoHS compliant and housed in a standard 0402 surface-mount package.

Fixed Inductors Feature Summary

• Unshielded thin film construction for high-frequency stability
• Ultra-low inductance value of 0.4 nH with tight ±0.1 nH tolerance
• High self-resonant frequency capability up to 6 GHz
• Surface-mount 0402 footprint design

Fixed Inductors Applications

• RF circuit impedance matching networks
• High-frequency signal filtering applications
• Broadband amplifier input/output stages
• Microwave communication system components

Fixed Inductors Procurement Notes

Verify the specific tolerance suffix, where 'B' denotes ±0.1 nH, against schematic requirements. Confirm that the 0.4 nH value aligns with target RF frequencies near the 6 GHz self-resonant limit. Ensure the 800 mA current rating exceeds peak operational currents. Check for RoHS compliance documentation if required by assembly standards.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance below 1 nH is required for RF tuning. The unshielded design suits applications where magnetic interference is minimal or managed. Consider the 0.1 Ω DC resistance for power loss calculations. The 0402 size fits dense PCB layouts. Validate thermal performance within the -40°C to +85°C operating range for the specific environment.

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 low inductance values from 0.2 nH to 33 nH. Variants differ primarily by inductance value and tolerance codes (e.g., B, C, S, F, G, H, J). All share the same 0402 package, thin film technology, and general electrical characteristics like the 6 GHz self-resonant frequency.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 0.4 nH inductance, ±0.1 nH tolerance, 0402 package, and 6 GHz self-resonant frequency. Verify that alternative manufacturers offer unshielded thin film variants with comparable 800 mA current ratings and 0.1 Ω DC resistance limits.
