Product Description
The CM1401-03 is a multichannel array with four lowpass filter + ESD channels and four ESD-only channels. They reduce EMI/RFI emissions on a data port and protect against ESD on a USB port. Each EMI/RFI channel integrates a high quality pi-style filter (C-R-C) which provides greater than 30dB attenuation in the 800-2700 MHz range relative to the pass band attenuation. These pi-style filters are bidirectional, controlling EMI both to and from a data port connector. The CM1401-03 provides a high-level of ESD protection on all eight channels for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The input pins 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 CM1401-03 is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package footprint and low weight. The CM1401-03 incorporates Optiguard™ coating which results in improved reliability at assembly and is available in a space-saving, low-profile chip scale package with optional lead-free finishing.
Applications
