EMI Filter Arrays
ON Semiconductor introduces four highly-integrated electromagnetic interference (EMI) filter arrays with electrostatic discharge (ESD) protection in thin DFN packages. Specifically designed for high-speed data interfaces in mobile phones, these 4-channel, 6-channel, and 8-channel filters provide reliability in a drop-in replacement footprint (1.35 × 3 mm). The devices deliver excellent S21 characteristics with low parasitic inductance (10 pH to 20 pH) due to the TDFN package ground pad. These devices are capable of attenuating unwanted signals over RF band between 800 MHz and 2.9 GHz. Each device features an application specific cut-off frequency (95 MHz to 110 MHz) optimized for LCD display and camera interfaces. The NUF4402 is a low capacitance 4-channel EMI filter with ESD protection designed for filtering signals in LCD display and camera interfaces with maximum data rate up to 54 Mbps per line. The NUF6401 is a 6-channel EMI filter with ESD protection that is capable of attenuating unwanted signals at 35 dB over radio frequency band between 800 MHz and 2.7 GHz. The NUF8401 is a low-capacitance 8-channel EMI filter with ESD protection designed for filtering data lines in LCD displays and camera interfaces with a maximum data rate of up to 54 Mbps per line.
