◆解說
 

Ihold	Hold current is the maximum current that UB Fuse can pass through without interruption at 20°C unless otherwise specified.
Itrip	Trip current is the minimum current that will switch the device from low resistance state to high resistance state at 20°C unless specified.
Vmax	The maximum voltage device can withstand without damage at rated current.
Imax	The maximum current device can withstand without damage at rated voltage.
Pd	The power dissipated from device when in the tripped state at 20°C unless otherwise specified.
R min	The minimum resistance of device as received from the factory at 20°C unless otherwise specified.
R max	The maximum resistance of device as received from the factory at 20°C unless otherwise specified.
R1max	The maximum resistance of device when measured one hour post trip at 20°C unless otherwise specified.
Max. Time-to-trip	The maximum time for device to trip at specified current ratings at 20°C unless otherwise specified.
