EMI Filters | CM1412
EMI Filter with ESD Protection, 2-Channel
Obsolete
概览
The CM1412 is a dual, low pass filter arrayr integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while providing ESD protection. This part is custom-designed to interface with a microphone port on a cellular telephon or similar device. Each high quality filter provides more than 35 dB attenuation in the 800 to 2700 MHz range. These pi stlye filters support bidirectional filtering that can address both EMI and ESD from and to the device. They also support AC signals, enabling audio signals to pass through without distortion.
- EMI filtering and ESD protection for headset/speaker ports
- Wireless handsets, Wireless handsets, MP3 players, Digital camcorders, Notebooks, & Desktop PCs
- Pi-style EMI filters in a capacitor-resistor-capacitor(C-R-C) network
- Greater than 40dB attenuation at 1GHz
- Extremely low lead inductance for optimum filter
and ESD performance
