EM4D-100L
DFN-8 package
Description
The EM4D-100L is a 2mm square DFN-8, 4 line low pass filter array with integrated TVS diodes. The EM4D-100L is
designed to suppress unwanted EMI/RFI signals and provide ESD protection for high-speed data interfaces such as
LCD displays and camera imagers for SMART phones.
With a desired cutoff frequency of 150MHz, the EM4D-100L provides good EMI/RFI attenuation better than 35dB in
the 800MHz - 3GHz bandwidth. This blocks RF noises from GSM, DCS or Bluetooth which can affect the baseband
chipset and other blocks. Coupled with the integrated TVS diodes, this device is able to meet IEC 61000-4-2 (ESD)
and 61000-4-4 (EFT) immunity requirements.
