Overview
The EOWS201212M261 is a surface mount common mode choke manufactured by Max Echo. It features a two-line configuration designed for electromagnetic interference suppression in compact electronic circuits. The component provides an impedance of 260 Ohms at 100 MHz and supports a current rating of 300 mA. Its direct current resistance (DCR) is specified at 400 mOhm, ensuring low power loss during operation.
Feature Summary
- Surface mount construction for automated assembly integration
- Two-line design for differential signal noise reduction
- Ferrite chip technology for effective EMI suppression
Applications
- Portable electronic devices requiring compact filtering
- Data line protection in consumer electronics
- Signal integrity enhancement in high-speed interfaces
Procurement Notes
Verify the manufacturer part number against official Max Echo documentation to ensure authenticity. Confirm that the surface mount package dimensions match your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 300 mA current rating meets your circuit's operational demands without saturation.
Selection Notes
Select this component when space constraints necessitate a small form factor common mode choke. The 260 Ohm impedance at 100 MHz suits applications targeting specific frequency noise profiles. Consider the 400 mOhm DCR for efficiency-sensitive designs. Verify that the 300 mA rating aligns with the maximum expected current in the protected lines to prevent performance degradation.
Part Context
This component belongs to the Max Echo multilayer chip inductor family, utilizing multi-layer printing and low-temperature co-firing technologies. Max Echo Technology Corp. specializes in magnetic materials and precision winding techniques for passive components. The EOWS series represents their surface mount solutions for EMI suppression in modern electronics.
Replacement Considerations
The EOWS453226M801 is a documented alternative from Max Echo offering 800 Ohm impedance and 1A current rating. Verify pin compatibility and impedance characteristics before substitution. Ensure the replacement fits the physical footprint and meets the specific noise suppression requirements of the application.
