DescriptionThe 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 30dB 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 ±15kV, 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 ±30kV.
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 Optiguard?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.
