TCM0403T-080-2P-T210

Overview

The TCM0403T-080-2P-T210 is a thin-film common mode filter manufactured by TDK Corporation. It features a compact 0403 package with dimensions of 0.45 mm length, 0.30 mm width, and 0.23 mm height. The component supports a maximum rated current of 50 mA and has a typical DC resistance of 1.2 Ohms per line. It offers a differential insertion loss cutoff frequency of 15.0 GHz, ensuring minimal impact on high-speed signal integrity. The device operates within a temperature range of -25°C to +85°C and provides a minimum common mode attenuation of 30 dB at 5.0 GHz.

Feature Summary

• Utilizes thin-film technology to achieve wideband differential transmission without degrading high-speed signal quality.
• Provides steep common mode attenuation in the 2.4 GHz and 5.0 GHz bands for effective electromagnetic interference suppression.
• Features an industry-standard ultra-small footprint suitable for space-constrained mobile and consumer electronics.

Applications

• Noise suppression for USB interfaces in smartphones and tablets
• EMI mitigation for HDMI connections in portable devices
• Signal integrity protection for LVDS and MIPI interfaces in wearable equipment

Procurement Notes

Verify the specific suffix T210 against official TDK documentation to confirm tape and reel specifications. Ensure compatibility with surface mount assembly processes given the 0.45 x 0.30 mm form factor. Cross-reference the 50 mA rating with system power requirements to prevent saturation. Confirm RoHS compliance status through the manufacturer's latest certification documents before integration.

Selection Notes

Select this component when designing circuits requiring noise filtering for high-speed differential signals under 50 mA. The 15.0 GHz cutoff frequency makes it suitable for applications where preserving signal bandwidth is critical. Consider the 0403 size constraint if board real estate is limited. Compare against the TCM0403T-200 variant if lower cutoff frequencies or different impedance characteristics are required for specific noise profiles.

Part Context

This part belongs to the TCM-T series of thin-film common mode filters from TDK. The series is engineered specifically for modern electronic devices that utilize high-speed data interfaces. These components address the growing need for electromagnetic compatibility in densely packed consumer electronics, offering a solution that balances performance with miniaturization requirements.

Replacement Considerations

The TCM0403T-200-2P-T210 is a related model within the same series but features a different cutoff frequency (8.0 GHz) and higher DC resistance (3.0 Ohms). Verify if the lower attenuation at 5.0 GHz provided by the 200 variant meets the specific EMC requirements of the design before substitution.

FAQ

What is the differential insertion loss cutoff frequency for this component?

The differential insertion loss cutoff frequency is typically 15.0 GHz, which ensures that high-speed differential signals pass through with minimal distortion.

How does the thin-film technology benefit high-speed signal transmission?

Thin-film technology allows the filter to maintain wideband differential transmission while providing sharp common mode attenuation, effectively suppressing noise without affecting the integrity of the desired signal.
