TF1028S-162Y1R3-01

Overview

The TF1028S-162Y1R3-01 is a through-hole common mode choke coil manufactured by TDK Corporation. It features a toroidal core design intended for AC power supply line filtering applications. The component supports a rated current of 1.3A and provides two lines of noise suppression capability. Key electrical specifications include a maximum DC resistance characteristic associated with the 1.3A rating and an inductance value indicated by the model suffix. The device is RoHS compliant and designed for standard industrial and consumer electronic environments requiring electromagnetic interference reduction on power lines.

Feature Summary

• Provides common mode noise suppression for AC power lines
• Toroidal core construction for efficient magnetic coupling
• Through-hole mounting configuration for robust mechanical attachment

Applications

• AC power supply input filtering
• Consumer electronics power line protection
• Industrial equipment EMI suppression

Procurement Notes

Verify the specific datasheet version for precise DC resistance and inductance tolerances, as these values are critical for circuit design. Confirm that the through-hole lead spacing matches the PCB layout requirements. Ensure the operating temperature range aligns with the target application environment. Check for any specific safety certifications required for the end product market.

Selection Notes

Select this component when a 1.3A current rating is sufficient for the power line application. The toroidal shape offers high efficiency in a compact volume compared to other core geometries. Consider the through-hole form factor if automated surface-mount assembly is not available or if higher mechanical strength against vibration is required for the installation site.

Part Context

This part belongs to the TF1028S series of common mode chokes from TDK. The series utilizes toroidal cores to minimize external magnetic fields while maximizing impedance to common mode noise. These components are widely used in power entry modules where space constraints and noise performance must be balanced for compliance with electromagnetic compatibility standards.

Replacement Considerations

Check for parts with identical current ratings and similar inductance values. Verify that alternative common mode chokes maintain the same physical footprint and lead spacing to ensure board compatibility without redesigning the PCB layout.
