CSPEMI306A 6 Channel EMI Filter Array with ESD Protection Features Product Description • • The CSPEMI306A is a six channel low-pass filter array that reduces EMI/RFI emissions while at the same time providing ESD protection. It is used on data ports on mobile devices. To reduce EMI/RFI emissions, the CSPEMI306A integrates a pi-style filter (C-R-C) for each of the 6 channels. Each high quality filter provides greater than 30dB attenuation in the 800-2700 MHz range. These pi-style filters also support bidirectional filtering, controlling EMI both to and from a data port connector. • • • • • • Six channels of EMI filtering for data ports Pi-style EMI filters in a capacitor-resistor-capacitor (C-R-C) network Greater than 32dB attenuation at 1GHz +15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) +30kV ESD protection on each channel (HBM) Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance 15-bump, 2.960mm X 1.330mm footprint Chip Scale Package (CSP) Lead-free version available Applications • • • • • • EMI filtering and ESD protection for both data and I/O ports Wireless Handsets Handheld PCs / PDAs MP3 Players Notebooks Desktop PCs In addition, the CSPEMI306A provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The input pins are designed and characterized to safely dissipate ESD strikes of 15kV, exceeding the maximum requirement of the IEC 61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the device provides protection for contact discharges to greater than 30kV. The CSPEMI306A is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package footprint and low weight. The CSPEMI306A is available in a space-saving, low-profile Chip Scale Package with optional lead-free finishing.
