TPD4F003DQDR

Overview

The TPD4F003DQDR is a four-channel EMI filter circuit with integrated electrostatic discharge (ESD) protection, manufactured by Texas Instruments. It features an RC Pi-filter topology designed for display interfaces. Key electrical parameters include a cutoff frequency of 200 MHz, capacitance of 8.5 pF, and resistance of 100 Ohms. The device operates within a temperature range of -40°C to +85°C and provides ±12kV ESD protection. It is housed in an 8-pin WSON package measuring 3.3 mm x 1.35 mm x 0.8 mm.

Feature Summary

• Integrates EMI filtering with ESD protection in a single compact component
• Utilizes RC Pi-filter architecture for effective noise suppression
• Provides high-level electrostatic discharge protection up to ±12kV

Applications

• Display interface signal lines
• Systems requiring EMI/RFI noise suppression
• Portable electronic devices with sensitive input/output ports

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the operating voltage rating of 5.5 V aligns with your system requirements. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when space constraints require combining EMI filtering and ESD protection functions. Ensure the 100 Ohm series resistance does not degrade signal integrity for your specific data rates. Verify that the 200 MHz cutoff frequency adequately attenuates interference without affecting desired signal bandwidth.

Part Context

This part belongs to the TPDxF003 family of EMI filters, which includes four-, six-, and eight-channel variants. These devices are engineered to suppress electromagnetic interference in systems exposed to noisy environments. The family shares similar internal architectures but varies in channel count and package options to suit different board layout densities.

Replacement Considerations

Check for other members of the TPDxF003 family, such as TPD6F003 or TPD8F003, if additional channels are needed. Verify pin-to-pin compatibility with alternative EMI filter arrays from other manufacturers if supply chain diversification is required.
