CM04RC01T

Overview

The CM04RC01T is a surface-mount common mode choke coil manufactured by Taiyo Yuden, designed for filtering noise on DC and signal lines. It features a dual-line configuration with a typical common mode impedance of 800 Ω at 100 MHz. The component supports a maximum DC current of 1.5 A and exhibits a low DC resistance of 60 mΩ. Its physical dimensions are 9.0 mm in length and 5.2 mm in width. Additionally, the device functions as a 1:1 RF transformer within the 0.5 to 300 MHz frequency range.

Feature Summary

• Dual-line construction for simultaneous noise suppression on paired signal or power conductors
• Capable of operating as a 1:1 RF transformer across a broad frequency spectrum
• Low DC resistance design minimizes voltage drop and power loss in high-current applications

Applications

• Filtering common mode noise in high-speed digital signal lines
• Noise suppression in DC power distribution circuits
• RF signal coupling and transformation in communication equipment

Procurement Notes

Verify the specific revision status before procurement, as availability may vary. Confirm that the 9.0x5.2 mm footprint matches the target PCB layout constraints. Ensure the 1.5 A current rating aligns with the maximum operational load of the circuit. Validate that the 800 Ω impedance specification meets the required noise attenuation levels at 100 MHz. Check for any discontinued status updates from the manufacturer prior to finalizing orders.

Selection Notes

Select this component when a compact solution is needed for both EMI filtering and RF signal handling. The dual functionality reduces board space compared to using separate chokes and transformers. Consider the 60 mΩ DC resistance for efficiency requirements in low-voltage systems. The wide frequency range up to 300 MHz makes it suitable for broadband applications. Ensure the mechanical size fits within the designated area of the assembly.
