Overview
The CTTF0402F-6N8B is a fixed thin film inductor from Central Technologies, designed for surface mount applications. It features an inductance of 6.8 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 DC resistance of 0.9 Ω. It supports a rated current of 260 mA and achieves a minimum quality factor of 13 at 500 MHz. The device is RoHS compliant and housed in a standard 0402 package.
Feature Summary
- Utilizes unshielded thin film technology for stable RF performance
- Offers precise inductance control with tight manufacturing tolerances
- Designed for high-frequency signal processing in compact layouts
Applications
- RF circuits requiring low inductance values
- High-frequency impedance matching networks
- Signal filtering in communication devices
Procurement Notes
Verify the specific suffix code 'B' corresponds to the required ±0.1 nH tolerance during ordering. Confirm that the 0402 footprint matches the target PCB design. Ensure the operating environment stays within the specified -40 °C to 85 °C range to maintain electrical stability. Cross-reference the 260 mA current rating against peak load requirements.
Selection Notes
Select this component when precise low-nanohenry inductance is critical for RF applications. The thin film construction provides superior stability compared to standard chip inductors. Consider the 0.9 Ω DC resistance impact on circuit efficiency. Verify compatibility with reflow soldering profiles suitable for thin film components.
Part Context
This part belongs to the CTTF0402F series, which offers various inductance values from 0.2 nH to 33 nH in the 0402 package. The series utilizes thin film technology to achieve tight tolerances and high Q-factors. Different suffixes indicate varying tolerance levels, allowing designers to balance precision and cost.
Replacement Considerations
Direct substitutes must match the 6.8 nH value, 0402 package, and thin film construction. Verify equivalent DC resistance and current ratings. Check if alternative manufacturers offer compatible tolerance codes for the same application requirements.
