Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/lofe information. 2. When switching inductive and/or capacitive loads, the effects of transient voltages and/or currents should be considered. Refer to Application Notes AN108A & AN107 for details. 3. Electrical Load Life Expectancy - Contact Littelfuse with voltage current values along with type of load. 4. Breakdown Voltage - Per MIL-STD-202, Method 301. 5. Storage Temperature - Long time exposure at elevated temperature may degrade solderability of the leads.
