Product Description

The CSPEMI200A is a quad low-pass filter array inte-

grating four pi-style filters (C-R-C) that reduce EMI/RFI

emissions while at the same time providing ESD pro-

tection. This device is custom-designed to interface

with the headset port on a cellular telephone, and con-

tains 3 different filter values. Each high quality filter

provides more than 20dB attenuation in the 800-2700

MHz range. These pi-style filters support bidirectional

filtering, controlling EMI both to and from the micro-

phone and speaker elements. They also support bipo-

lar signals, enabling audio signals to pass through

without distortion.

In addition, the CSPEMI200A provides a very high

level of protection for sensitive electronic components

that may be subject to electrostatic discharge (ESD).

The CSPEMI200A can safely dissipate ESD strikes of

international

(Method 3015) specification for Human Body Model

(HBM) ESD, the device provides protection for contact

discharges to greater than

The CSPEMI200A is particularly well suited for porta-

ble electronics (e.g., cellular telephones, PDAs, note-

book computers) because of its small package format

and low weight. The CSPEMI200A is available in a

space-saving, low-profile Chip Scale Package with

optional lead-free finishing.
