CM04RC02T

Overview

The CM04RC02T is a surface-mount common mode choke coil manufactured by Taiyo Yuden, designed for DC and signal line filtering. It features a three-line configuration with a rated maximum DC current of 500 mA. The component exhibits a maximum DC resistance (DCR) of 180 mOhms per line. At a frequency of 100 MHz, the impedance is specified at 1 kOhms. The device operates within a temperature range of -25°C to +105°C and utilizes a horizontal package with four鸥翼 terminals.

Feature Summary

• Provides common mode noise suppression for three parallel signal or power lines
• Designed for surface-mount assembly on printed circuit boards
• Constructed for operation in environments ranging from -25°C to +105°C

Applications

• Filtering noise on multi-line data interfaces
• Signal integrity protection in portable electronic devices
• Common mode interference suppression in automotive electronics

Procurement Notes

Verify the specific revision status and availability as this component may be subject to discontinuation notices. Confirm that the three-line configuration aligns with the schematic requirements, as two-line variants exist within the same series. Ensure the 500 mA current rating meets the operational load without exceeding thermal limits defined in the official datasheet.

Selection Notes

Select this component when a three-line filtering solution is required rather than standard dual-line chokes. The 180 mOhms DCR must be evaluated against voltage drop constraints in the target circuit. Verify that the 1 kOhm impedance at 100 MHz provides sufficient attenuation for the specific noise frequencies present in the application environment.

Part Context

This part belongs to the CM04RC series of common mode chokes from Taiyo Yuden. It is distinct from the CM04RC09T, which is a two-line variant with different current and impedance characteristics. The CM04RC02T specifically addresses applications requiring simultaneous filtering of three conductors within a compact surface-mount footprint.

Replacement Considerations
