Product profile

1.1 General description

The IP4041CX25 is a 10-channel RC low-pass filter array which is designed to provide

filtering of undesired RF signals. In addition, the IP4041CX25 incorporates diodes to

provide protection to downstream components from ElectroStatic Discharge (ESD)

voltages as high as

±20 kV contact according the IEC 61000-4-2 standard, far exceeding

level 4.

The IP4041CX25 is fabricated using monolithic silicon technology and integrates

10 resistors and 20 diodes in a single Wafer-Level Chip-Scale Package (WLCSP).

These features make the IP4041CX25 ideal for use in applications requiring the utmost in

miniaturization such as mobile phone handsets, cordless telephones and personal digital

devices.
