Product Description

The CSPEMI204 is a low-pass filter array designed

specifically to reduce EMI/RFI emissions and provide

ESD protection for a headset port on a cellular and

mobile devices. The CSPEMI204 integrates two high

quality, pi-style filters (C-R-C) filters, one for a micro-

phone and one for an earpiece or speaker, each pro-

viding more than 30dB attenuation relative to the pass

band attenuation in the 800-2700 MHz range. These

filters support bidirectional filtering, reducing EMI both

to and from the headset port and support bipolar audio

signals without distortion.

In addition, the CSPEMI204 provides a very high level

of protection for sensitive electronic components that

may be subject to electrostatic discharge (ESD). The

CSPEMI204 can safely dissipate ESD strikes of ±8kV,

the maximum requirement of the IEC 61000-4-2 inter-

national standard. Using the MIL-STD-883 (Method

3015) specification for Human Body Model (HBM)

ESD, the device provides protection for contact dis-

charges to greater than ±15kV. The CSPEMI204 pro-

tects sensitive components such as CPU and DSPs

that have much weaker internal ESD protection cir-

cuitry usually only intended for mechanical handling

protection.

The CSPEMI204 is particularly well-suited for portable

electronics because of its small package format and

low weight. The CSPEMI204 is available in a space-

saving, low-profile Chip Scale Package with optional

lead-free finishing.
