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.
Coating color, marking and dimensions are different depending on the manutactuing base. Verify them on the delivery specification.
