CCD area image sensor S9970/S9971 series
s Specifications of built-in temperature sensor
A chip thermistor is built in the same package with a CCD chip, and the CCD chip temperature can be monitored with it. A
relation between the thermistor resistance and absolute temperature is expressed by the following equation.
RT1 = RT2 × exp BT1/T2 (1/T1 - 1/T2)
1 MΩ
RT1: Resistance at absolute temperature T1 [K]
RT2: Resistance at absolute temperature T2 [K]
BT1/T2: B constant [K]
The characteristics of the thermistor used are as follows.
R298=10 kΩ
B298/323=3450 K

q Handle these sensors with bare hands or wearing cotton gloves. In addition, wear anti-static clothing or use a wrist strap, in
order to prevent electrostatic damage due to electrical charges from friction.
q Avoid directly placing these sensors on a work-desk or work-bench that may carry an electrostatic charge.
q Provide ground lines or ground connection with the work-floor, work-desk and work-bench to allow static electricity to
discharge.
q Ground the tools used to handle these sensors, such as tweezers and soldering irons.
It is not always necessary to provide all the electrostatic measures stated above. Implement these measures according to the
amount of damage that occurs.
s Element cooling/heating temperature gradient rate
When using an external cooler, the element cooling/heating temperature gradient rate should be set at less than 5 K/min.
