Description
The EMIF10-LCD02F3 is a 10-line highly integrated device designed to suppress EMI/RFI noise in all systems subjected to electromagnetic interference. The EMIF10 Flip-Chip packaging means the package size is equal to the die size.
This filter includes ESD protection circuitry, which prevents damage to the protected device when subjected to ESD surges up 15 kV.
Lead-free Flip-Chip package (24 bumps)
