Overview
The CM08RB01 is a leaded common mode choke coil manufactured by Taiyo Yuden, designed for DC and signal lines. It features a 2-line configuration with a case size of 13.0x9.5 mm. Key electrical parameters include a common mode impedance of 2500 Ω typical at 30 MHz, a minimum common mode inductance of 40 µH, and a maximum DC resistance of 40 mΩ. The component supports a rated current of 2 A and a rated voltage of 50 V.
Feature Summary
- Provides common mode noise suppression for DC and signal lines
- Designed for through-hole mounting applications
- Features a robust ferrite core construction
Applications
- DC line filtering
- Signal line noise suppression
- Common mode interference reduction in electronic circuits
Procurement Notes
Verify the specific revision or suffix if available, as some sources indicate this part may be discontinued. Confirm that the 2.5 kOhm impedance specification aligns with your design requirements at 30 MHz. Ensure the through-hole package dimensions (13.0x9.5 mm) fit your PCB layout constraints before finalizing procurement decisions.
Selection Notes
Select this component when high common mode inductance (min 40 µH) is required for effective noise filtering. The 2 A rated current makes it suitable for power lines carrying moderate currents. Consider the 40 mΩ DC resistance for efficiency calculations in low-voltage applications. The leaded package simplifies assembly compared to surface-mount alternatives.
Part Context
This component belongs to Taiyo Yuden's series of leaded common mode choke coils. These components are engineered to suppress electromagnetic interference on dual-line configurations. The CM08RB01 specifically targets applications requiring reliable noise attenuation without the complexity of surface-mount soldering processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if sourcing from alternative distributors due to potential discontinuation status.
