HBWS2012-R18J

Overview

The HBWS2012-R18J is an unshielded wirewound inductor from Max Echo Technology, housed in a 0805 (2015 Metric) surface-mount package. It features a ceramic core and offers an inductance of 180 nH with a tolerance of ±5%. The component has a maximum DC resistance of 780 mΩ and a current rating of 400 mA. Its self-resonant frequency is 900 MHz, measured at a test frequency of 100 MHz.

Feature Summary

• Unshielded wirewound construction utilizing ceramic core material for stable magnetic properties
• Surface-mount design compatible with standard 0805 footprint manufacturing processes
• High self-resonant frequency capability suitable for RF signal filtering applications

Applications

• RF circuit filtering
• Signal processing networks
• General-purpose electronic device power management

Procurement Notes

Verify the specific manufacturer datasheet to confirm the exact electrical tolerances and thermal characteristics before integration. Ensure that the supply chain documentation explicitly identifies Max Echo Technology as the producer to avoid counterfeit components. Cross-reference the part number suffixes against official catalogs to confirm the presence of the specified ceramic core and unshielded configuration.

Selection Notes

Select this component when a compact 0805 form factor is required for low-inductance RF applications. The unshielded design necessitates careful PCB layout to prevent electromagnetic interference with nearby sensitive traces. Evaluate the 400 mA current limit against peak load requirements to ensure reliable operation without saturation or excessive heating during continuous duty cycles.

Part Context

This inductor belongs to Max Echo's fixed inductor portfolio, which utilizes precision winding and low-temperature co-firing technologies. The company specializes in multilayer chip inductors and magnetic components, serving various consumer and industrial electronics markets with standardized passive components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative suppliers by matching the 180 nH inductance, 0805 package dimensions, and 400 mA current rating specifications.
