7. ATTENTION 

(1)Please read this specification before use the product.

(2)Please do not expose posistor to any abnormal environment.Or it may deteriorate posistor's character, worsely,may cause malfunction(or damage).

●Please use posistor within the specified maximum voltage.

●When this product is operated,please make sure that surrounding parts and inserting material can withstand the temperature.If the surrounding part and materials is kept under such condition,they may be deteriorated or may produce harmful gas(C12,H2S,NH3,Sox,Noxetc.).And,such harmful gas may deteriorate the element.

●This product does not have waterproof construction. A splashed water may cause failure mode such as decline of characteristic or current leak.

●The ceramic element of this product is fragile,and care must be taken not to load a excessive pressforce or not to give a shock at handling,Such forces may cause cracking or chipping.
