Features
- Two channels of EMI filtering Pi-style EMI filters in a capacitor-resistor-capacitor (C-R-C) network Greater than 40dB attenuation at 1GHz +8kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) +15kV ESD protection in each channel (HBM) Supports AC signals—ideal for audio applications Extremely low lead inductance for optimum filter and ESD performance 5-bump, 0.950mm X 1.410mm footprint Chip Scale Package (CSP) Lead-free version available
Applications
EMI filtering and ESD protection for headset speaker ports Wireless Handsets Handheld PCs / PDAs MP3 Players Digital Camcorders Notebooks Desktop PCs Product Description The CSPEMI201A is a dual low-pass filter array inte- grating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while at the same time providing ESD pro- tection. This part is custom-designed to interface with a speaker port on a cellular telephone or similar device. Each high quality filter provides more than 35dB atten- uation in the 800-2700 MHz range. These pi-style fil- ters support bidirectional filtering, controlling EMI both to and from a speaker element. They also support bipolar signals with a cutoff frequency of 31MHz, enabling audio signals to pass through without distor- tion. In addition, the CSPEMI201A provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The CSPEMI201A 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 CSPEMI 201A 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 CSPEMI201A is available in a space-saving, low-profile Chip Scale Package with optional lead-free finishing.

Note 2: ESD applied to input and output pins with respect to GND, one at a time. Note 3: Clamping voltage is measured at the opposite side of the EMI filter to the ESD pin. For example, if ESD is applied to Pi n A1, then clamping voltage is measured at Pin C1. Note 4: Unused pins are left open Note 5: These parameters are guaranteed by design and characterization.
