IP3053CX5, IP3053CX10, IP3053CX15 and IP3053CX20 is a 2, 4, 6 and 8-channel LC low-pass filter array family which is designed to provide filtering of undesired RF signals on the I/O ports of portable communication or computing devices. In addition, IP3053CX5, IP3053CX10, IP3053CX15 and IP3053CX20 incorporates diodes to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages as high as ±8 kV according IEC 61000-4-2 level 4. The devices are fabricated using monolithic silicon technology and integrate and incorporate up to 8 inductors and up to 16 diodes in a 0.5 mm pitch Wafer-Level Chip-Scale Package (WLCSP).
