CSPEMI201A: EMI Filter with ESD Protection, Headset Speaker
The CSPEMI201AG is a dual low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while at the same time providing ESD protection. 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 attenuation in the 800-2700 MHz range. 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 31MHz, enabling audio signals to pass through without distortion.
Features- Two lines of EMI suppression with integrated ESD protection
- Extremely low lead inductance for optimum filter and ESD performance
| Benefits- Suppresses noise off of strong analog and digital audio lines, provides ESD protection in a monolythic Chip Scale Package
- Using Chip Scale Packaging to eliminate the long wires associated with packaging
|
Applications- Audio interfaces on wireless devices
| End Products- Cellular phones, notebook computers, netbook computers, portable navigation devices
