The product out of expiration date shall not be used Within a suitable application, the parts temperature depends on circuit design and certain heat dissipation conditions. This should be double checked in a worst case operation mode. In normal case, the max.standard operating temperature of +150C should not be exceeded. For higher operating temperature conditions, please contact Panasonic representative in your area.
