UF1815SG-650Y4R0-01

Overview

The UF1815SG-650Y4R0-01 is a two-line common mode choke manufactured by TDK Corporation, designed for through-hole mounting. It features an inductance of 65 mH and supports a current rating of 4 A. The component exhibits a direct current resistance (DCR) of 30 mOhm. This filter is engineered to suppress electromagnetic interference in dual-line circuits, providing high impedance at applicable frequencies while maintaining low insertion loss for the differential signal path.

Feature Summary

• Provides effective common mode noise suppression for two-line configurations
• Engineered with high self-resonant frequency characteristics
• Supports through-hole assembly for robust mechanical integration

Applications

• Power supply input filtering
• Data line noise suppression
• General electronic equipment EMI reduction

Procurement Notes

Verify the complete part number including suffixes against official TDK documentation to ensure correct inductance and current ratings. Confirm package type and pin configuration match design requirements. Check for specific environmental certifications if required by the target application standards.

Selection Notes

Select this component when dual-line common mode noise attenuation is required at 65 mH. Ensure the operating current does not exceed 4 A to prevent saturation. Verify that the 30 mOhm DCR meets system power loss constraints. Consider physical size constraints for through-hole placement on the PCB.

Part Context

This component belongs to TDK's UF1815SG series of common mode chokes. The series offers various inductance values and current ratings. These components are widely used in consumer electronics and industrial equipment for electromagnetic compatibility compliance.

Replacement Considerations

Check TDK datasheets for other UF1815SG variants with matching 65 mH inductance and 4 A rating. Verify equivalent DCR and physical dimensions before substitution.
