Overview
The TF3524V-702Y4R0-01 is a through-hole common mode choke manufactured by TDK Corporation. It is designed for line filtering applications with a minimum inductance of 7mH and a maximum current rating of 4.0A. The component features a low DC resistance of 0.1 ohms, ensuring efficient power transmission while suppressing electromagnetic interference.
Feature Summary
- Provides effective common mode noise suppression for AC line circuits
- Supports high current handling up to 4.0A with minimal voltage drop
- Utilizes through-hole mounting for robust mechanical stability
Applications
- AC line input filtering in consumer electronics
- Electromagnetic interference suppression in industrial power supplies
- Horizontal filter stages in display backlight inverters
Procurement Notes
Verify the complete part number including suffixes against official TDK documentation to ensure correct electrical specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure storage conditions align with component sensitivity requirements.
Selection Notes
Select this component when a 7mH minimum inductance and 4.0A current capacity are required for common mode noise reduction. Evaluate the physical footprint and pin configuration for compatibility with existing PCB layouts. Compare DC resistance values against system efficiency targets to minimize power loss in the circuit path.
Part Context
This component belongs to TDK's TF3524 series of common mode chokes, which are engineered for high-reliability applications in power supply lines. The series utilizes ferrite materials optimized for broad frequency noise attenuation, supporting various current ratings within the same form factor family.
Replacement Considerations
Check for direct substitutes such as the TF3524B-702Y4R0-01 variant. Verify that alternative parts match the 7mH inductance and 4.0A current ratings exactly. Ensure pinout compatibility and thermal characteristics are identical to avoid redesigning the host circuit board.
