EMIF01-1003M3

1 line IPAD™, EMI filter and ESD protection in Micro QFN package

Features

■ Single line EMI symmetrical (I/O) low-pass filter

■ High efficiency in EMI filtering

■ Very low PCB space consumption:

1.0 mm x 0.6 mm

■ Very thin package: 0.6 mm max

■ High efficiency in ESD suppression

(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

■ Easy layout and flexibility due to single line

topology

■ Low capacitance

Complies with following standards

■ IEC 61000-4-2 level 4 input and output 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:

■ Keyboard for mobile phones

■ Computers and printers

■ Communication systems

■ MCU boards

Description

The EMIF01-1003M3 is a 1 line highly integrated

device designed to suppress EMI/RFI noise in all

systems exposed to electromagnetic interference.

This filter includes ESD protection circuitry, which

prevents damage to the application when

subjected to ESD surges up to 15 kV on all pins.
