• Wirewound construction on a ceramic core for stable performance
• High Q factor and self-resonant frequency characteristics suitable for RF circuits
• Surface-mount package optimized for automated pick-and-place assembly

Fixed Inductors Applications

• RF filter networks
• Impedance matching circuits
• General purpose high-frequency signal processing

Fixed Inductors Procurement Notes

Verify the specific suffix 'NG' against the manufacturer's official datasheet to confirm terminal plating composition and compliance status. Ensure the ordering code matches the required inductance value of 18 nH and tolerance. Confirm that the package dimensions align with the PCB footprint requirements before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 18 nH is required for high-frequency applications. Consider the 1000 mA current rating and 0.025 Ω DCR for power loss calculations. Evaluate the operating temperature range of -40°C to +125°C against environmental conditions. Compare Q-factor specifications at target frequencies with alternative suppliers if circuit sensitivity is critical.

Fixed Inductors Part Context

This part belongs to the CT0402HPF series of SMD wire-wound chip inductors manufactured by Central Technologies. The series is characterized by higher Q and lower DCR compared to standard 0402 inductors. These components are engineered for applications requiring excellent current handling capability and very high self-resonant frequencies, supporting values from 1.0 to 220 nH.

Fixed Inductors Replacement Considerations

Cross-reference with other 0402 wirewound inductors offering 18 nH ±2% tolerance. Verify compatibility of DCR, IDC, and physical dimensions. Check for equivalent Q-factor performance at the intended operating frequency. Ensure replacement parts maintain RoHS compliance and similar thermal characteristics.
