EOWS201212M121

Overview

The EOWS201212M121 is a two-line surface mount common mode choke manufactured by Max Echo. It provides an impedance of 120 Ohms at 100 MHz and supports a current rating of 370 mA. The component features a direct current resistance (DCR) of 300 mOhm. Designed for compact electronic assemblies, it effectively suppresses common mode noise in high-frequency circuits while maintaining low insertion loss for differential signals.

Feature Summary

• Surface mount construction for automated assembly
• Two-line configuration for differential signal protection
• High impedance performance at 100 MHz

Applications

• Embedded systems noise suppression
• Industrial automation signal lines
• General electronics EMC filtering

Procurement Notes

Verify the complete part number including suffixes against official Max Echo documentation to ensure correct impedance and tolerance specifications. Confirm package dimensions and terminal compatibility with your PCB footprint before ordering. Request manufacturer datasheets for detailed electrical characteristics and reliability testing data.

Selection Notes

Select this component when a compact surface mount solution is required for common mode noise reduction in low-current applications. Ensure the 370 mA current rating meets the operational requirements of the target circuit. Verify that the 120 Ohm impedance at 100 MHz aligns with the specific frequency range of the interference being mitigated.

Part Context
