◆解說
 

Ihold	保持電流是 UB Fuse 在 20°C 時可以不間斷通過的最大電流，除非另有說明。
Itrip	跳閘電流是在 20°C 時將器件從低電阻狀態切換到高電阻狀態的最小電流，除非另有說明。
Vmax	器件在額定電流下可以承受而不損壞的最大電壓。
Imax	器件在額定電壓下所能承受而不損壞的最大電流。
Pd	除非另有說明，否則設備在 20°C 時處於跳閘狀態時消耗的功率。
R min	除非另有說明，否則為 20°C 時從工廠收到的器件的最小電阻。
R max	除非另有說明，否則為 20°C 時從工廠收到的設備的最大電阻。
R1max	除非另有說明，否則在 20°C 下跳閘後一小時測得的設備最大電阻。
Max. Time-to-trip	除非另有說明，否則設備在 20°C 下在指定電流額定值下跳閘的最長時間。
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.
