chip carrier (Case 867) and the small outline chip carrier
(Case 482). A fluorosilicone gel isolates the die surface and
wire bonds from the environment, while allowing the pressure
signal to be transmitted to the sensor diaphragm. The
MPX4115A series pressure sensor operating characteristics,
and internal reliability and qualification tests are based on use
of dry air as the pressure media. Media, other than dry air,
may have adverse effects on sensor performance and long-
term reliability. Contact the factory for information regarding
media compatibility in your application.
