– -34 dB at 900 MHz
– -20 dB between 800 MHz and 2.2 GHz
■ Very low PCB space consumption
■ Thin package: 0.6 mm max
■ Lead-free package
■ High reduction of parasitic elements through
integration
Complies with the following standards:
■ IEC 61000-4-2 level 4 input and output pins:
– ±15 kV (air discharge)
– ±8 kV (contact discharge)
Applications
■ Mobile phones
■ Notebook, laptop
■ Portable devices
■ PND
Description
The ECMF04-4AMX12 is a highly integrated
common mode filter designed to suppress
EMI/RFI common mode noise on high speed
differential serial buses like MIPI D-PHY or MDDI.
The ECMF04-4AMX12 can protect and filter 2
differential lines.
