CM1400-03

CM1400-03 6 Channel EMI Filter Array with ESD Protection Product Description The CM1400−03 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 CM1400−03 integrates a pi−style filter (C−R−C) for each of the 6 channels. Each high quality filter provides greater than 30 dB attenuation in the 800−2700 MHz range relative to the pass band attenuation. These pi−style filters also support bidirectional filtering, controlling EMI both to and from a data port connector. In addition, the CM1400−03 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 ±15 kV, 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 ±30 kV. The CM1400−03 is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package footprint and low weight. The CM1400−03 incorporates OptiGuardt coating which results in improved reliability at assembly. The CM1400−03 is available in a space−saving, low−profile chip scale package with RoHS−compliant lead−free finishing. Features h...
