EMIF03-SIM02M8
3 line IPAD™, EMI filter for SIM card applications
Features
■ SIM card EMI low-pass filter
■ High efficiency in EMI filtering
■ 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 external
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

■ IEC 61000-4-2 level 4 external pins
– 15 kV (air discharge)
– 8 kV (contact discharge)
■ IEC 61000-4-2 level 2 internal pins
– 2 kV (air discharge)
– 2 kV (contact discharge)
■ MIL STD 883G - Method 3015-7 Class 3A (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 EMIF03-SIM02M8 is a 3 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 the
external pins.
