REF. CL OF OVERLAP Note: SPST-NO = Single-pole, single-throw, normally open Notes: 1. Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/life 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 and 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.
