Texas Instruments has introduced six- and four-channel electromagnetic interference (EMI) filters for LCD display applications.

Electrostatic discharge (ESD) ratings exceed the IEC 61000-4-2 specification by at least three times for contact discharge.

The TPD6F202 and TPD4F202 devices are both 67% better than the specification for air-gap discharge, said the supplier.

This allows the signal to be transmitted through the device while it filters out the higher frequency RF and electromagnetic interferences (RF/EMI) that can appear as lines on a screen, especially LCD displays.

ESD protection rating is +/-25kV with less RF/EMI from the signal antenna in a mobile to the screen delivers a clearer LCD display.

Both devices are available in a WCSP package with 0.4 mm lead pitch and flow-through pin-mapping.
