Common Mode Chokes Overview

The ECMS1V0704-301-R is a surface-mount common mode choke from the Eaton ECMS-R series. It features two lines with an impedance of 300 Ohms at 100 MHz and a maximum DC resistance of 10 mOhms. The component supports a rated current of 5 A and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 7.50 mm in length, 6.00 mm in width, and 3.80 mm in height. The device is unshielded and utilizes SMD/SMT termination for PCB mounting.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for power line applications
• Supports high current handling up to 5 A with low DC resistance
• Designed for surface mount installation on printed circuit boards

Common Mode Chokes Applications

• Power supply input filtering
• Noise suppression in electronic equipment
• Common mode interference reduction in signal lines

Common Mode Chokes Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before integration. Confirm that the surface-mount footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check RoHS compliance status if required by project specifications.

Common Mode Chokes Selection Notes

Select this component when a compact, high-current common mode choke is required for surface-mount designs. The 5 A rating suits applications needing significant current capacity without excessive voltage drop. The 300 Ohm impedance at 100 MHz provides effective attenuation for typical EMI frequencies. Consider the unshielded design if magnetic coupling with nearby components is a concern.
