DESCRIPTION/ORDERING INFORMATION  
The TPD4F003, TPD6F003, and TPD8F003 are 4-, 6-, and 8-channel EMI filters in space-saving 0.4-mm pitch  
DQD packages. The low-pass filter arrays reduce EMI emissions and provide system level ESD protection.  
Because of its small package and easy-to-use pin assignments, the TPDxF003 filters ar suitable for a wide array  
of applications such as mobile handsets, PDAs, video consoles, notebook computers, etc. In particular, these  
filters are ideal for EMI filtering and protecting data lines from ESD at the LCD display, keypad, and memory  
interfaces.
