Overview

CM1483 is an L-C EMI filter array with ESD protection, which integrates two Pi-filters (C-L-C) for the headset speaker. The CM1483 has component values of 100pF-3nH-100pF. The parts include ESD protection diodes on all input/output pins, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD diodes connected to the filter ports safely dissipate ESD strikes of ±8 kV, beyond 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 ±15 kV.

  • Headset speaker port in mobile handsets
  • EMI filtering for data ports in cell phones, PDAs or notebook computers

  • 2 channels of EMI filtering
  • ±8 kV ESD protection (IEC 61000-4-2, contact discharge)
  • ±15 kV ESD protection (HBM)
  • Greater than -40 dB of attenuation at 1.0 GHz
  • I/O port protection for mobile handsets, notebook computers, PDAs, etc.
