Three electromagnetic interference (EMI) filter arrays with electrostatic discharge (ESD) protection in Thin DFN (TDFN) packages are designed for high-speed LCD display and camera data interfaces with maximum data rates up to 54 Mbits/s per line. Signal components from 800 MHz to 2.9 GHz are attenuated by at least 25 dB. The typical 3-dB point is 110 MHz. All three arrays exhibit extremely low parasitic inductance (10 to 20 pH) due to their TDFN-package ground pads. ON Semiconductor's four-channel NUF4402 costs $0.25 each in 10,000-unit quantities. The six-channel NUF6401 is $0.33 per unit, and the eight-channel NUF8401 is $0.44. ED Online 9509
