Product Description

The CSPEMI306A 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 CSPEMI306A 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. These pi-style filters also

support bidirectional filtering, controlling EMI both to

and from a data port connector.

In addition, the CSPEMI306A provides a very high

level of protection for sensitive electronic components

that may be subjected to electrostatic discharge

(ESD). The input pins safely dissipate ESD strikes of

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

The CSPEMI306A is particularly well suited for

portable electronics (e.g., cellular telephones, PDAs,

notebook computers) because of its small package

footprint and low weight. The CSPEMI306A is

available in a space-saving, low-profile Chip Scale

Package with optional lead-free finishing.
