SPQ0410HE5H-PB
Slim UltraMini SiSonic
TM
Microphone
The SPQ0410HE5H-PB is a miniature, high-
performance, low power, top port silicon
microphone. Using Knowles’ proven high
performance SiSonic
TM
MEMS technology,
the SPQ0410HE5H-PB consists of an
acoustic sensor, a low noise input buffer,
and an output amplifier. These devices are
suitable for applications such as cellphones,
smart phones, laptop computers, sensors,
digital still cameras, portable music
recorders, and other portable electronic
devices where excellent wideband audio
performance and RF immunity are required.
Features:
Extremely narrow package
Low Current
Enhanced RF protection
Ultra-Stable Performance
Standard SMD Reflow
Omnidirectional
