However the applied voltage shall not exceed the value of 4 times the maximum operating voltage. No evidence of flaming or self-flaming. Precautions for Use 20 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. Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
