Product Overview

The CM1484 is a dual-channel pi-style EMI filter array with integrated ESD protection, housed in a compact 5-lead SC-70 package. It offers component values of 11 pF - 100 - 11 pF per channel, with a cut-off frequency of 220 MHz, suitable for data rates up to 80 Mbps. The integrated ESD diodes provide robust protection against electrostatic discharge, safely dissipating strikes up to 15 kV (IEC61000-4-2) and 30 kV (HBM). Its small package and convenient pin assignments make it ideal for portable electronics, including mobile handsets, PDAs, and notebook computers, specifically for filtering and protecting data and control lines for I/O ports, LCD displays, and camera interfaces.
