dimensions

f = 1KHz, 1Pa Vs = 2 ~ 1.5 V dc

2 V dc (standard), 10 V dc (max.)

2.2 KΩ

f = 1KHz, 1Pa

100 ~ 20,000 Hz

0.5 mA max.

56 dBA

Vs = 2 V dc RL = 2.2KΩ

f = 1KHz, 1Pa A-weighted

-20 ~ +70° C

ø6 x 2.7 mm

0.±0 g max.

pin type (hand soldering only)

yes

weight

material

terminal

RoHS

note:

We use the “Pascal (Pa)” indication of sensitivity as per the recomendation of I.E.C. (International

Electrotechnical Commission). The sensitivity of “Pa” will increase 20dB compared to the “uꢀar”

indication. Example: -60dB (0dB = 1V/uꢀar) = -40dB (1V/Pa)
