Overview
The HBWS2012-R27J is a fixed wirewound inductor manufactured by Max Echo, designed for surface-mount applications. It features an unshielded construction within a standard 0805 (2015 Metric) package footprint. The component provides an inductance value of 270 nH with a tolerance of ±5%. It supports a maximum DC current rating of 350 mA and exhibits a maximum DC resistance of 1.46 Ohms. The self-resonant frequency is specified at 850 MHz, indicating its suitability for high-frequency signal processing tasks.
Feature Summary
- Unshielded wirewound construction for specific magnetic field requirements
- Standard 0805 surface-mount package for automated assembly compatibility
- High self-resonant frequency capability for RF signal integrity
Applications
- RF filtering circuits
- Signal conditioning modules
- High-frequency power supply stages
Procurement Notes
Verify the exact suffix designation against official Max Echo documentation to ensure correct tolerance and packaging specifications. Confirm that the unshielded design aligns with electromagnetic interference constraints in the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a compact 0805 form factor is required alongside precise 270 nH inductance values. Ensure the 350 mA current limit meets circuit demands and consider the unshielded nature regarding nearby sensitive components or layout spacing requirements.
Part Context
This part belongs to Max Echo's HBWS series of fixed inductors, which utilizes precision winding technology. The series targets applications requiring reliable passive components in space-constrained electronic designs, offering standardized electrical characteristics across various inductance values within the same physical envelope.
Replacement Considerations
Cross-reference with HBLS2012-R27J if multilayer ceramic construction is acceptable instead of wirewound. Verify pinout and thermal performance similarities before substituting to maintain circuit stability.
