EMIF04-1005M8
4-line IPAD™
low capacitance EMI filter and ESD protection in micro QFN package
Features
■ EMI symmetrical (I/O) low-pass filter
■ High efficiency in EMI filtering: -34 dB at
frequencies from 900 MHz to 1.8 GHz
■ Very low PCB space consumption:
1.7 mm x 1.5 mm
■ Very thin package: 0.6 mm max
■ High efficiency in ESD suppression on input
pins (IEC 61000-4-2 level 4)
■ High reliability offered by monolithic integration
■ High reduction of parasitic elements through
integration and wafer level packaging
■ Lead-free package
Complies with following standards:
■ IEC 61000-4-2 level 4 input pins
– 15 kV (air discharge)
– 8 kV (contact discharge)
■ MIL STD 883G - Method 3015-7 Class 3B
(all pins)
Applications
Where EMI filtering in ESD sensitive equipment is
required:
■ LCD and camera for mobile phones
■ Computers and printers
■ Communication systems
■ MCU boards
Description
The EMIF04-1005M8 is a 4-line highly integrated
device designed to suppress EMI/RFI noise in all
systems exposed to electromagnetic interference.
This filter includes an ESD protection circuitry,
which prevents damage to the application when
subjected to ESD surges up to 15 kV on the input
pins.
