Notes:
4. Electrical Load Life Expectancy - Contact Littelfuse with voltage, and current values, along with
type of load.
5. This resistance value is for 300 mm wire length. Resistance changes when wire lengthens.
6. Operate (including bounce)/Release Time - per diode suppressed coil (Coil ).
7. Shock and Vibration - per EIA/NARM RS-421-A and MIL-STD-202.
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. Leakage current is less than 0.1mA for 60 seconds.
