CTTF0402F-8N0B

Overview

The CTTF0402F-8N0B is an unshielded thin film chip inductor from Central Technologies, designed for surface-mount applications. It features a nominal inductance of 8 nH with a tight tolerance of ±0.1 nH (Code B). The component operates within a temperature range of -55°C to +155°C and has a maximum DC resistance of 1.1 Ohms. It supports a maximum rated current of 220 mA and offers a self-resonant frequency up to 6 GHz, making it suitable for high-frequency RF circuits.

Feature Summary

• Unshielded thin film construction for high-frequency stability
• Ultra-tight inductance tolerance of ±0.1 nH
• Extended operating temperature range up to 155°C

Applications

• RF matching networks
• High-speed digital signal filtering
• Impedance matching in communication devices

Procurement Notes

Verify the specific suffix 'B' confirms the ±0.1 nH tolerance during ordering. 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.

Selection Notes

Select this part when ultra-low inductance values with minimal deviation are required. The 0402 package suits space-constrained designs. Consider the 1.1 Ohm DC resistance and 220 mA current limit against circuit requirements. Compare against other tolerance codes if wider variance is acceptable.

Part Context

This component belongs to the CTTF0402F series of thin film chip inductors. The series provides various inductance values from 0.2 nH to 33 nH. Different suffix letters indicate varying tolerance levels, with 'B' representing the highest precision at ±0.1 nH.

Replacement Considerations

Compatible substitutes include CTTF0402F-8N0C (±0.2 nH) and CTTF0402F-8N0S (±0.3 nH) for relaxed tolerance needs. Other manufacturers offering 8 nH 0402 thin film inductors may be considered if electrical parameters match.
