This device is custom-designed to interface with the headset port on a cellular telephone, and contains 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 microphone and speaker elements. They also support bipolar 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 +8kV, 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 +15kV. The CSPEMI200A is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook 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.
