AOZ8043
AOZ8043 is 4-Line EMI Filter manufactured by Alpha & Omega Semiconductors.
Description
The AOZ8043 is an 4-line device integrating EMI filtering with ESD protection for each line. It is designed to suppress unwanted EMI/RFI signals and provide electrostatic discharge (ESD) protection in portable electronic equipment. This state-of-the-art device utilizes AOS leading edge Trench Vertical Structure [TVS]2 ™ technology for superior clamping performance and filter attenuation over the full operating display range. The AOZ8043 has been optimized for protection of color LCD displays and CCD camera lines in cellular phones and other portable consumer electronic devices.
The AOZ8043 consists of four identical circuits prised of TVS diodes for ESD protection, and a resistor- capacitor network for EMI/RFI filtering. A series resistor value of 100Ω and a capacitance value of 9p F are used to achieve -20d B minimum attenuation from 1.0GHz to 3.0GHz. The TVS diodes provide effective suppression of...
