Features

Eight channels of EMI filtering �30kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) �30kV ESD protection on each channel (HBM) Better than 35dB of attenuation at 800-2700MHz Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance x 1.458mm footprint Chip Scale Package OptiGuardTM coated version available for improved reliability at assembly Lead-free version available

California Micro Device's is an EMI filter array with ESD protection, which integrates eight Pi- filters (C-R-C). The CM1405 has component values of 25pF100-25pF. The parts include avalanche-type ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD diodes connected to the filter ports safely dissipate ESD strikes of �30kV, exceeding the maximum requirement of the IEC61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than �30kV. This device is particularly well-suited for portable electronics (e.g. mobile handsets, PDAs, notebook computers) because of its small package and easy-to-use pin assignments. In particular, the CM1405 is ideal for EMI filtering and protecting data lines from ESD for the LCD display in mobile handsets. The CM1405-03 incorporates OptiGuardTM coating which results in improved reliability at assembly and is available in space-saving, low-profile chip-scale packages with optional lead-free finishing.

Applications

LCD data lines in mobile handsets EMI filtering & ESD protection for high-speed I/O ports EMI filtering for high-speed data lines Wireless handsets Cell phones Notebook computers PDAs / Handheld PCs
