CM1812X330R-00

Overview

CM1812X330R-00 is a surface-mount common mode choke manufactured by Laird-Signal Integrity Products. It features a monolithic design with two lines and operates in the CM series. The component provides an impedance of 33 Ohms at 100 MHz and supports a maximum rated current of 10A. Its DC resistance (DCR) is 3 milliohms. The device is housed in an 1812 (4532 Metric) package with four leads, measuring 0.180 inches in length and 0.120 inches in width.

Feature Summary

• Monolithic construction for compact surface-mount integration
• Dual-line configuration for effective common mode noise suppression
• High current handling capability suitable for power line filtering

Applications

• Power supply input filtering
• Data bus noise suppression
• EMI reduction in high-current circuits

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and material specifications. Ensure compatibility with existing PCB footprint dimensions and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring high current capacity alongside significant common mode attenuation. Evaluate the trade-off between low DC resistance and impedance performance at target frequencies. Confirm that the 1812 package size fits within the available board space constraints.
