SM5430/SM5470
Low Cost Packaged Pressure Sensors
Surface Mount and DIP Pressure Sensors Low-Cost Packaged Die
DESCRIPTION
Silicon Microstructures provides its two most
popular pressure sensor die in surface
mount dual in-line package (SO16)
configuration. All parts in these series are
uncompensated high-performance die
mounted in an injection-molded package
designed for surface mounting.
These packaged sensor die provide a way
for OEM manufacturers to incorporate
pressure sensors at costs close to raw die
prices, without the need to handle, attach or
wire bond silicon sensor die.
Options include variety of pressure ranges,
absolute or gauge pressure types, and a
choice of cap configurations. The result is a
versatile product line suitable for a wide
range of applications.
The low-pressure series (model
SM5470)
incorporates Silicon Microstructure’s unique
low-pressure die to achieve high
performance in pressure ranges from 0.15
PSI to 3.0 PSI full-scale in gauge and
differential.
The model
SM5430
comes in gauge,
differential, and absolute for pressure
ranges from 5 PSI to 60 PSI full scale.
