CM1812X330R-10

Overview

The CM1812X330R-10 is a surface-mount common mode choke manufactured by Laird-Signal Integrity Products. It features a monolithic design with two lines, rated for a maximum current of 10A and a DC resistance (DCR) of 3 milliohms. The component provides an impedance of 33 Ohms at 100 MHz. It operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Monolithic construction for compact surface-mount integration
• High current handling capability suitable for power line filtering
• Low DC resistance to minimize signal loss and heat generation

Applications

• Power supply input filtering
• Signal line noise suppression
• EMI reduction in high-current circuits

Procurement Notes

Verify the specific package dimensions and terminal configuration against the official datasheet before integration. Confirm that the 10A rating aligns with the thermal management capabilities of the target PCB layout. Ensure compliance with project-specific environmental regulations such as RoHS3 requirements.

Selection Notes

Select this component when high current capacity is required alongside effective common mode noise attenuation. The low DCR makes it suitable for applications where voltage drop must be minimized. Consider the 1812 footprint size relative to available board space and assembly equipment capabilities.
