Endevco® Model 40931 Micro-miniature ?Flip-Chip? MEMS Pressure Transducer Die

Product catalog summary

Overview: The Endevco® model 40931 is a silicon pressure sensor designed for applications requiring micro-miniature size. It measures 1.65 mm x 1.2 mm x 0.4 mm and is suitable for surface mount installation using conductive epoxy. The sensor is ideal for medical OEM applications.

Specifications: The sensor has a full-scale range of 0-15 psia and provides a nominal 200 mV full-scale output with a 5 Vdc excitation. It features a uniquely sculptured diaphragm for high sensitivity, overpressure capability, and excellent linearity. The electrical configuration includes a four-arm piezoresistive bridge with a supply voltage of 5 Vdc recommended and 12 Vdc maximum. Input and output resistance range from 1000 to 2300 Ω.

Physical Characteristics: The sensor's dimensions are 0.065 x 0.047 x 0.016 inches (1.65 x 1.19 x 0.41 mm). It can be mounted using wire bond or conductive epoxy.

Environmental Characteristics: The operating temperature range is -47˚F to +212˚F (-55˚C to +100˚C). The sensor is designed for compatibility with dry, clean gases, and inquiries regarding other media exposure should be directed to the factory.

Quality Assurance: Meggitt ensures high reliability through stringent quality control and corrective action procedures. Specifications are subject to change without notice as part of continuous product improvement.

Endevco® Model 40931 Micro-miniature ?Flip-Chip? MEMS Pressure Transducer Die-1

Model 40931 Silicon MEMS pressure sensor Features • Microminiature pressure die • 15 psia full scale range • Designed for surface mount installation • Ideal for medical OEM applications The Endevco® brand model 40931 flip chip is a unique silicon pressure sensor designed to address applications where micro-miniature size is required. The unit measures only 1.65 mm long by 1.2 mm wide by 0.4 mm tall. Four connection pads allow for the sensor to be “flip chip” mounted to a circuit or substrate using conductive epoxy. The top of the sensor represents the active sensing element for measurement of absolute pressures. The sensor has a full scale range of 0-15 psia, and a nominal 200 mV full scale output when powered using a sensor excitation of 5 Vdc. A uniquely sculptured diaphragm provides high sensitivity, high overpressure capability and excellent linearity.
