DESCRIPTION/ORDERING INFORMATION
The TPD3F303 is a 3-ch integrated EMI filter for SIM interface. This device integrates a V_CC clamp to provide
system level ESD protection at the V_CC line. Termination resistor value of 47 Ω is included on the CLK line, while
a 100 Ω termination is employed at the DATA and RST line.
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 TPD3F303 filter is suitable for a wide array of applications such
as mobile handsets, PDAs, video consoles, notebook computers, etc.
The TPD3F303 is designed to suppress EMI/RFI noise in systems subjected to electromagnetic interferences.
These filter series include an ESD protection circuitry which prevents damage to the application when subjected
to ESD stress far exceeding IEC 61000-4-2 (Level 4). The TPD3F303 is specified for –40°C to 85°C operation.
