SPW2430HR5H-B
Top Port SiSonicTM Microphone
The SPW2430HR5H-B is a miniature, highperformance, low power, top port silicon
microphone. Using Knowles’ proven high
performance SiSonicTM MEMS technology,
the SPW2430HR5H-B 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 audio performance and RF
immunity are required.

(A) MSL (moisture sensitivity level) Class 1.
(B) Maximum of 3 reflow cycles is recommended.
(C) In order to minimize device damage:
 Do not board wash or clean after the reflow process.
 Do not brush board with or without solvents after the reflow process.
 Do not directly expose to ultrasonic processing, welding, or cleaning.
 Do not insert any object in port hole of device at any time.
 Do not apply over 30 psi of air pressure into the port hole.
 Do not pull a vacuum over port hole of the microphone.
 Do not apply a vacuum when repacking into sealed bags at a rate faster than 0.5 atm/sec.
