CM1443-08CP

Overview

The CM1443-08CP is an 8-channel EMI filter array with integrated ESD protection, designed for high-speed LCD and camera interfaces. It utilizes a Pi-filter RC circuit topology to suppress electromagnetic interference across the 800 MHz to 3 GHz frequency range. The device provides 25 dB attenuation and features a capacitance of 7.5 pF and resistance of 200 Ohms per channel. Packaged in a compact TDFN-16 surface-mount format measuring 3.4 mm x 1.45 mm x 0.8 mm, it operates within a temperature range of -40°C to +85°C.

Feature Summary
