• Supports high current applications with a 5 A rating and minimal 10 mOhm DC resistance
• Designed for automated assembly via standard surface mount technology

Common Mode Chokes Applications

• Battery protection circuits
• Power line filtering
• Common mode noise suppression

Common Mode Chokes Procurement Notes

Verify the specific impedance value of 450 Ohms at 100 MHz against design requirements. Confirm the 5 A current rating and 10 mOhm DCR limits are sufficient for the target application. Ensure compatibility with the specified 80 V DC voltage rating and operating temperature range of -40°C to +125°C before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when high current handling up to 5 A is required alongside significant noise attenuation. The low profile 3.80 mm height and compact 7.50 x 6.00 mm footprint make it suitable for space-constrained PCB layouts. Consider the 10 mOhm DCR for efficiency calculations in power-sensitive designs.

Common Mode Chokes Part Context

This part belongs to the Eaton ECMS-R series of common mode chokes, which offer current ratings up to 15 A and DC resistances ranging from 5 mOhms to 75 mOhms. The series is designed for robust performance in demanding electronic environments, providing reliable noise filtering for various power and signal lines.

Common Mode Chokes Replacement Considerations

Cross-reference with other ECMS1V0704 variants such as ECMS1V0704-301-R or ECMS1V0905-701-R if different impedance or current characteristics are needed. Verify pinout and physical dimensions match the existing PCB footprint before substitution.
