CSPEMI201AG

The CSPEMI201AG is a dual low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while providing ESD protection. It is custom-designed to interface with a speaker port on a cellular telephone or similar device.

Each high quality filter provides more than 35 dB attenuation in the 800-2700 MHz range and greater than 40 dB attenuation at 1 GHz. These pi-style filters support bidirectional filtering, controlling EMI both to and from a speaker element. They also support bipolar signals with a cutoff frequency of 31 MHz, enabling audio signals to pass through without distortion.

The CSPEMI201AG provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). It can safely dissipate ESD strikes of ±8 kV per the IEC 61000-4-2 standard and provides protection for contact discharges to greater than ±15 kV per the Human Body Model (HBM) specification.

The device is available in a space-saving, low-profile 5-UFBGA WLCSP package measuring 1.41 mm x 0.93 mm x 0.65 mm. It is surface mountable and operates over a temperature range of -40°C to 85°C.
