4-Channel LCD and Camera EMI Filter with ESD Protection

Favorite

Overview

The CM1408 is a pi-style EMI filter array with ESD protection, which integrates four filters (C-R-C) in a small form factor, TDFN 0.50mm pitch package. The CM1408 has component values of 8.5pF-100 Ω -8.5pF per channel. The CM1408 has a high cut-off frequency and can be used in applications with data rates up to 44 Mbps. The parts include ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components against electrostatic discharge (ESD). The ESD protected diodes safely dissipate ESD strikes of ±15 kV, which even exceeds the maximum requirement of the IEC61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±30 kV.

  • I/O port protection for mobile handsets, notebook computers, PDAs etc.
  • EMI filtering for data ports in cell phones, PDAs or notebook computers.
  • LCD and Camera data lines in mobile handsets
  • Cellular Phones, Smartphones, Netbooks, Notebooks, Portable Navigation Devices, e-Readers
  • 4 channels of EMI filtering with integrated ESD protection
  • Greater than -35 dB attenuation (typical) at 1 GHz
  • ±15 kV ESD protection (IEC 61000-4-2, contact discharge)
