For subminiature circuit protection where short circuit currents may
be as high as 300 amperes. Low resistance values, high-speed
action, insulated terminations, encapsulated epoxy-coated body. Will
withstand vibrations of 10-55 Hz per method 201 of MIL-STD-202,
and of 55-2000 Hz at 10 Gs per method 204, test condition C, of
MIL-STD-202, and shock of 100 Gs for 6 milliseconds per method
213, test condition I of MIL-STD-202. Operating Ambient
Temperature: Ð55¡C to 125¡C. At Ð55¡C current carrying capacity is
110% of rating; at 25¡C, 100% of rating; at 125¡C, 80% of rating.
Fuses will withstand an axial pull of 7 pounds. Voltage Rating: 125 V
