CM08RB04

Overview

The CM08RB04 is a leaded common mode choke coil manufactured by Taiyo Yuden, designed for DC and signal line applications. It features two lines with a maximum rated current of 3A and a DC resistance (DCR) of 40 mOhm. The component exhibits an impedance of 2 kOhms at 70 MHz. It utilizes a rectangular package construction suitable for through-hole mounting.

Feature Summary

• Provides effective noise suppression for both DC power and signal lines
• Constructed as a leaded component for reliable through-hole integration
• Engineered to handle high current loads up to 3A

Applications

• DC power line filtering
• Signal line noise reduction
• Electronic equipment EMI suppression

Procurement Notes

Verify the specific datasheet version when sourcing, as product information may be subject to change without notice. Confirm that the leaded package type matches the target PCB layout requirements. Ensure the 3A current rating and 40 mOhm DCR specifications align with the circuit design constraints before finalizing procurement decisions.

Selection Notes

Select this component when through-hole mounting is required for common mode chokes in high-current environments. The 2 kOhm impedance at 70 MHz makes it suitable for specific frequency noise attenuation needs. Consider the physical dimensions of the rectangular package to ensure adequate clearance on the printed circuit board during the design phase.

Part Context

This part belongs to the CM08 series of common mode chokes from Taiyo Yuden. The series includes various models tailored for different current and impedance requirements. The CM08RB04 specifically addresses applications needing robust leaded components for filtering DC and signal lines in general electronic equipment.

Replacement Considerations

Cross-reference with other CM08 series variants if current or impedance values differ from project requirements. Verify pin compatibility and physical footprint before substituting with similar leaded common mode chokes from other manufacturers.
