ST EMIF02-USB05F2 User Manual
IPAD™
2 line EMF filter including ESD protection
Main application
When EMI filtering is ESD sensitive equipment is
required:
■ Mobile phones and communication systems
■ Computers, printers and MCU boards
Description
The EMIF02-USB05F2 is a highly integrated array
designed to suppress EMI / RFI noise for USB
port filtering. The EMIF02-USB05F2 Flip-Chip
packaging means the package size is equal to the
die size.
Additionally, this low-pass filter includes an ESD
protection circuitry to prevent damage to the
application when subjected to ESD surges up
to 15 kV.
This device is designed to be fully compatible with
USB standards.
