CAMD&primes CM1420 and CM1422 are EMI filter arrays with ESD protection, which integrate six and eight Pi- filters (C-R-C), respectively. The CM1420/22 has component values of 15pF-100OHM-15pF. These devices include ESD protection 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 ±15kV, beyond 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 pins are protected for contact discharges at greater than ±30kV.

CM1422 is particularly well suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of its small package format and easy-to-use pin assignments. In particular, the CM1420/22 is ideal for EMI filtering and protecting data lines from ESD for the LCD display in clamshell handsets.

The CM1420 and CM1422 incorporate OptiGuard™ coating which results in improved reliability at assembly. The CM1420 and CM1422 are available in space-saving, low-profile chip-scale packages with RoHS compliant lead-free finishing.
