CM04RC08T

Overview

The CM04RC08T 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 typical common mode impedance of 1 kOhms at 200 MHz. The component supports a rated current of 500 mA and has a maximum DC resistance (DCR) of 200 milliohms. Rated for a DC voltage of 50V, it operates within a temperature range of -25°C to +105°C. The physical dimensions are approximately 9.0 mm in length, 5.3 mm in width, and 4.4 mm in maximum height, housed in a horizontal 4-lead鸥翼 package.

Feature Summary

• Provides effective noise suppression for three-line signal and power circuits through high common mode impedance.
• Compact surface mount design facilitates automated assembly and space-constrained PCB layouts.
• Low DC resistance minimizes power loss and voltage drop in the filtered lines.

Applications

• Filtering electromagnetic interference in high-speed data transmission interfaces
• Noise suppression for multi-line signal processing circuits
• Common mode noise reduction in industrial control system wiring

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure compliance with project requirements. Confirm that the component matches the discontinued status noted in public records, as availability may be limited to existing stock or last-time buy scenarios. Ensure handling procedures account for the surface mount package type during assembly.

Selection Notes

Select this component when a three-line filtering solution is required for signals operating up to 200 MHz. The 500 mA current rating suits moderate load applications, while the low DCR ensures efficient power delivery. Consider the physical footprint constraints against the 9.0 x 5.3 mm dimensions before finalizing the PCB layout.

Part Context

This part belongs to the CM04 series of common mode chokes from Taiyo Yuden, which are engineered for suppressing common mode noise in electronic circuits. The series offers various line configurations and impedance values to suit different filtering needs. The CM04RC08T specifically addresses three-line applications requiring higher impedance characteristics compared to standard two-line variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative sourcing should focus on verifying functional equivalence regarding impedance, current rating, and physical dimensions with other manufacturers' three-line common mode chokes.
