MAIN APPLICATION

ESD protection and EMI filtering for USB port.

■

DESCRIPTION

The EMIF02-USB01 is a highly integrated array
designed tosuppress EMI / RFI noisefor USB port
filtering.

The EMIF02-USB01 flip-chip packaging means
the package size is equal to the die size. That's
why EMIF02-USB01 is a very small device.

Additionally, this filter includes an ESD protection
circuitry which prevents the protected device from
destruction when subjected to ESD surges up to
15 kV.
