Overview
The Max Echo HBWS2012-18NJ is a fixed wirewound inductor designed for surface-mount applications. It features an unshielded construction within an 0805 (2015 Metric) package. The component provides an inductance of 18 nH with a self-resonant frequency of 3.3 GHz. It supports a current rating of 600 mA and maintains a maximum DC resistance of 80 mOhm. The device operates reliably within a temperature range of -40°C to 125°C, ensuring stability in high-frequency circuit environments.
Feature Summary
- Unshielded wirewound construction for specific RF characteristics
- High self-resonant frequency suitable for high-speed signals
- Compact 0805 surface-mount footprint
Applications
- RF filter circuits
- High-frequency signal processing
- General-purpose SMD inductive components
Procurement Notes
Verify the exact self-resonant frequency specification against the manufacturer's latest datasheet, as sources indicate values of 3.3 GHz or 3.6 GHz. Confirm that the 0805 package dimensions align with your PCB layout requirements. Ensure the 600 mA current rating meets the operational demands of your specific circuit design before finalizing procurement.
Selection Notes
Select this component when an unshielded wirewound inductor is required for high-frequency applications. The 18 nH value and 0805 size make it suitable for space-constrained designs. Consider the 80 mOhm DCR limit for power loss calculations. Verify compatibility with reflow soldering profiles specified for the -40°C to 125°C operating range.
Part Context
This part belongs to the Max Echo HBWS series of fixed inductors. The series utilizes precision winding technology combined with professional magnetic materials. The HBWS2012-18NJ specifically addresses needs for low-inductance, high-frequency performance in compact electronic assemblies.
Replacement Considerations
Cross-reference with other 18 nH, 0805 package inductors from different manufacturers if supply constraints exist. Ensure substitute parts match the 600 mA current rating and 80 mOhm DCR specifications to maintain circuit performance.
