Product Information, Precautions and Warnings - IMPORTANT Before use, please read the following carefully as the product use in improper conditions may shorten product life. Please confirm the functional life in your usage conditions ahead of actualinstallations. Although TDK makes its utmost effort to constantly improve reliability of its product quality, your misuse may cause the product malfunctioning and property damage and/or human injury. For this reason, TDK requests that customers use the products with sufficient handling care and add a safeguard design upon your application so as to prevent malfunctioning of your systems, serious damages, personal accidents, fires and other possible damages, which may result from using these products of ours. Precaution: The product s operating life is limited because the products are constantly exposed to various environments when used. For this reason, thisoperating lif must be taken into consideration before use. (1)Storage Store the products within theabsolute maximum rating specified. Do not store the products in dusty places or in places where corrosive gases are generated. When storing CHS series humidity sensors for long(over 1 year) or storing in places with high temperature and high humidity or where sudden temperature change may occur, the humidity-sensitive film on the sensor elements as well as the solderability of the terminals of the sensor unit may deteriorate to cause output changes in excess of the guaranteed ranges. (2)Operating Environment and Conditions Use CHS series within theabsolute maximum rating of the operating environmental conditions specified. Electrically, such as input voltages, please stay within our electrical specifications. Avoid usage in locations subject to corrosive gases or excessive dust as these may cause the element s deterioration, resulting in output changes in excess of guaranteed ranges. Please consider measures to keep the corrosive gases from entering the sensor unit, for example, by a special jig to seal it, particularly during a solder flow process where flux-decomposed gases generate. Avoid usage in locations subject to excessive dewing or to water or salt water, as it may deteriorate the element to cause output changes in excess of guaranteed ranges. (3)Handling Applying excessive physical impacts to the sensor, such as by dropping, should be strictly avoided. Avoid applying excessive mechanical stress onto the product, for instance, when forming the terminals, for it may cause damages to the component. Revision Records Rev. Date Revised Revision By Div.
