CM1422

CM1420, CM1422 LCD EMI Filter Array with ESD Protection Description The 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 15 pF − 100 W − 15 pF. 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 ±15 kV, well 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 ±30 kV. This device 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...
