CM08RA20

Overview

The CM08RA20 is a leaded common mode choke coil manufactured by Taiyo Yuden, designed for noise suppression on DC and signal lines. It features a two-line configuration with a rated current of 5.5A and an impedance of 500 Ohms at 200 MHz. The component operates within a 50V voltage range and exhibits a low DC resistance of 20mOhm. Constructed as a through-hole device, it serves as a data line filter to mitigate electromagnetic interference in electronic circuits.

Feature Summary

• Provides common mode noise suppression for dual-line configurations
• Engineered for use on both DC power and signal transmission lines
• Features low DC resistance to minimize power loss during operation

Applications

• Data line filtering in electronic systems
• Noise suppression for DC power circuits
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the specific datasheet version before final selection, as specifications may vary. Confirm that the through-hole package style matches the target PCB layout requirements. Ensure the 5.5A current rating and 500 Ohm impedance meet the circuit's noise suppression and load conditions. Check RoHS compliance status if required by project regulations.

Selection Notes

Select this component when dual-line common mode noise reduction is required for DC or signal paths. The 5.5A rating suits moderate current applications, while the 500 Ohm impedance targets higher frequency interference. Verify that the through-hole mounting method aligns with the assembly process and mechanical constraints of the design.

Part Context

This part belongs to Taiyo Yuden's family of leaded common mode choke coils. These components are specialized passive devices intended for EMI/RFI suppression.
