TCM0403S-350-2P

Overview

The TCM0403S-350-2P is a two-channel common mode filter choke designed for ultra-high-speed differential signal lines. It features an impedance of 35 Ohms at 100 MHz and an inductance of 49 nH. The component supports a maximum DC current of 50 mA with a maximum DC resistance of 3.9 Ohms. Its compact surface-mount package measures 0.45 mm in length, 0.3 mm in width, and 0.25 mm in height. The device operates within a temperature range of -25°C to +85°C.

Feature Summary

Engineered specifically for filtering noise on ultra-high-speed differential signal lines.
Provides effective common mode noise suppression with low insertion loss characteristics.

Applications

High-speed serial data interface protection
Differential signaling line noise filtering
Compact electronic device EMC mitigation

Procurement Notes

Verify the specific suffix (e.g., T210) against official TDK documentation to confirm packaging details such as reel or cut tape specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a footprint smaller than standard EIA packages while maintaining performance for high-frequency signals. Confirm that the 50 mA current rating meets the operational requirements of the differential pair to avoid saturation issues during peak signal activity.

Part Context

This component belongs to the TCM-S series from TDK, which specializes in miniature common mode chokes. The series is characterized by its ability to handle high-speed data rates while occupying minimal PCB area, making it suitable for modern portable and high-density electronics where signal integrity is critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult TDK technical support for verified equivalents if this specific model is unavailable.
