Nominal Resistance measured with < 10% rated current. 3. Contact Littelfuse if application transient surges are less than 1 ms. 4. Nominal Voltage Drop measured at rated current after temperature has stabilized. Devices designed to carry rated current for 4 hours minimum. It is recommended that devices be operated continuously at no more than 80% rated current. See Temperature Re-rating Curvefor additional re-rating information.
