Mitsumi Temperature Sensors

Mitsumi offers cost effective temperature sensors in a miniaturized surface mount platform for applications requiring low power consumption, small size, and fast response time. Our temperature switches are available with hysteresis function ideal for consumer electronics over-heating protection. These sensors are available with either analog or digital output (I2C) for monitoring applications. For non-contact application we offer infrared technology temperature sensing with low noise and digital output.

Digital Temperature Sensor ICs

Our I2C digital sensors are available with RTD and Infrared sensing technology. Infrared sensor using MEMS thermopile technology. Measures surface temperature without contact by capturing infrared ray radiation from object.

Temperature Switch ICs

Temperature switch ICs sense the ambient temperature of the IC and switch the IC output at the detected temperature

Analog Temperature Sensor ICs

High-accuracy temperature sensor IC that can linearly output the voltage in response to changes in temperature
