TDK CHS-CSC-20

This specification applies to the temperature and humidity sensor products to be delivered. The product name defined in this specification is CHS-CSC-20.

• Store the product within the specified "Absolute Maximum Ratings."
• Do not store the product in dusty locations or places where corrosive gases may be generated.
• Storing CHS series humidity sensors for extended periods (over 1 year), or in high-temperature/high-humidity environments or locations subject to sudden temperature changes, may degrade the moisture-sensitive film on the sensor element and the solderability of the sensor unit terminals, causing output variations to exceed the guaranteed range.
• Use CHS series products within the specified operating conditions defined under "Absolute Maximum Ratings." For electrical parameters such as input voltage, ensure they remain within the electrical specification range.
• Avoid use in environments with corrosive gases or excessive dust, as these may degrade the element and cause output variations to exceed the guaranteed range. Consider implementing measures to prevent corrosive gases from entering the sensor unit — for example, using a dedicated jig to seal the unit during soldering, particularly when flux decomposition generates gases.
• Avoid use in environments with excessive condensation, water, or saltwater, as these may degrade the element and cause output variations to exceed the guaranteed range.
• Excessive physical shock to the sensor, such as dropping, must be strictly avoided.
• Avoid applying excessive mechanical stress to the product — for example, during terminal forming — as this may damage the element.
