California Micro Device&primes CM1405 is an EMI filter array with ESD protection, which integrates eight Pi- filters (C-R-C). The CM1405 has component values of 25pF-100-25pF. 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 are designed and characterized to 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.

CM1405 is particularly well suited for portable electronics (e.g. mobile handsets, PDAs, notebook computers) because of its small package format 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 OptiGuard™ coating which results in improved reliability at assembly and is available in space-saving, low-profile chip-scale packages with optional lead-free finishing.
