To insure accuracy and reliability do not exceed zero power current rating. 2. Do not exceed 5mW power rating or zero power current rating. 3. The Life Test Specification is based on operation at +25°C. Operation at higher temperatures may have an impact on the life expectancy of the component. 4. Component performance should be tested under actual application conditions to determine its suitability for a particular application. Contact NIC is you have questions regarding a particular application.
