CTTF0402F-1N8B

Overview

The CTTF0402F-1N8B is a fixed thin film inductor manufactured by Central Technologies, designed for surface mount applications. It features an inductance of 1.8 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 rated current of 560 mA. Its DC resistance is 200 mΩ max, with a self-resonant frequency of 6 GHz. The package size is 0402 (1005 metric), and it is RoHS compliant.

Feature Summary

• Thin film construction for high-frequency stability
• Unshielded design suitable for compact layouts
• Tight inductance tolerance options available

Applications

• RF circuits requiring precise low-inductance values
• Impedance matching networks
• High-speed digital signal filtering

Procurement Notes

Verify the specific tolerance suffix (e.g., B for ±0.1nH) when ordering, as the base series offers multiple precision codes. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure storage conditions align with standard surface mount device handling guidelines to maintain performance integrity prior to assembly.

Selection Notes

Select this component for applications demanding sub-nanohenry precision in a minimal footprint. The thin film technology ensures superior Q-factor and stability compared to standard multilayer types at high frequencies. Consider the unshielded nature for placement relative to sensitive components to prevent unwanted coupling effects in dense PCB designs.

Part Context

This part belongs to the CTTF0402F series of thin film chip inductors from Central Technologies. The series covers a wide range of inductance values from 0.2 nH to 33 nH, utilizing various tolerance codes such as F, G, H, J, and specific nanohenry codes like B, C, and S for ultra-precision requirements.

Replacement Considerations

Direct substitutes include other 0402 thin film inductors with 1.8 nH nominal value and ±0.1 nH tolerance. Verify that alternative parts match the 560 mA current rating and 200 mΩ DC resistance specifications to ensure circuit compatibility without modification.
