TPD8F003DQDR

Overview

The TPD8F003DQDR is an eight-channel EMI filter circuit manufactured by Texas Instruments, designed for display interfaces. It utilizes an RC (Pi) filter topology with a cutoff frequency of 200 MHz and operates within a frequency range up to 1 GHz. The device provides 25 dB attenuation and features integrated capacitance of 8.5 pF and resistance of 100 Ohms. Packaged in a WSON-16 surface-mount format measuring 3.3 mm x 1.35 mm x 0.8 mm, it supports operation between -40°C and +85°C.

Feature Summary

• Integrates eight channels of low-pass filtering for effective electromagnetic interference suppression
• Combines EMI filtering capabilities with electrostatic discharge protection functions
• Utilizes compact WSON package architecture to minimize footprint on printed circuit boards

Applications

• Display interface signal lines
• Portable electronic devices requiring space-saving solutions
• High-speed data transmission paths susceptible to radio frequency interference

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration when sourcing components. Confirm that the WSON-16 package dimensions align with your board layout requirements. Ensure thermal management strategies account for the specified operating temperature range during integration. Cross-reference the manufacturer datasheet for precise handling and soldering guidelines to maintain component integrity.

Selection Notes

Select this component when designing circuits requiring simultaneous EMI suppression and channel density for display interfaces. The 200 MHz cutoff frequency suits applications where signal integrity must be preserved above standard audio frequencies while attenuating higher-frequency noise. Consider the WSON-16 package size relative to available PCB real estate compared to larger through-hole alternatives.

Part Context

This part belongs to the TPD8F003 series of EMI filter arrays from Texas Instruments. The series offers four-, six-, and eight-channel configurations to accommodate varying interface complexity. These filters are engineered specifically for portable applications where minimizing electromagnetic emissions is critical for regulatory compliance and system performance.

Replacement Considerations

Consult official substitution lists for compatible variants within the same family. Verify pin compatibility and electrical specifications before replacing existing inventory. Generic equivalents may not match the integrated ESD protection characteristics or exact parasitic values.
