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. Breakdown Voltage - per MIL-STD-202, Method 301. 

4. Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load. 

5. This resistance value is for 11.81mm wire length. Resistance changes when wire lengthens. 

6. Operate (including bounce)/Release Time - per EIA/NARM RS-421-A, diode suppressed coil (Coil II). 

7. Shock and Vibration - per EIA/NARM RS-421-A and MIL-STD-202. 

8. For custom modifications to the wire length or size, or adding a special connector, please contact Littelfuse.
