Precautions for Use 20 Water and moisture may affect and change the high resistance range of this product largely. Consult us in advance when you consider using this product for such applications that may cause serious damage. Ionic impurities such as flux etc. attached to these products or mounted onto PCB, negatively affect the moisture resistance, corrosion resistance, etc. Ionic substances like sweat and salt that may be caused according to the storage environment, mounting conditions and mounting environment, also affect the above characteristics. Wash thoroughly these ionic substances. Confirm the reliability of washing and decide the dry conditions so that washing solvent is not to be remained inside the product after washing. Do not apply electricity to the product nor use the product itself until the drying is fully completed. Be careful to handle these resistors because outer coatings are comparatively weak to outer shock due to flameproof special coats. Please wash them to a minimum. No external force is given to the coating films until they are well dried because the coating films become weaker right after washing. The original strength will be returned after they are dried, so please pay attention not to apply any external force onto the coating film of resistors for 20 minutes after drying. Especially no PC boards shall be piled up. Feb. 2019 Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
