■Performance

For resistors operated at an ambient temperature of 70℃ or above, a power rating shall be

derated in accordance with the above derating curve.

■Precautions for Use

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

・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.
