I
hold
= Hold current: maximum current device will pass without tripping in 23°C still air.
I
trip
= Trip current: minimum current at which the device will trip in 23°C still air.
V
max
= Maximum voltage device can withstand without damage at rated current (I
max
)
I
max
= Maximum fault current device can withstand without damage at rated voltage (V
max
)
P
d
= Power dissipated from device when in the tripped state at 23°C still air.
R
min
= Minimum resistance of device in initial (un-soldered) state.
R
1max
= Maximum resistance of device at 23°C measured one hour after tripping.
Caution:
Operation beyond the specified rating may result in damage and possible arcing
and flame.
* Effective January 1, 2010, all 16R PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 16R PTC products may continue to be sold, until supplies are depleted.

中风发生时，一切都是以秒来计算的。延误治疗可能导致大脑重大损伤。伦敦大学医学院的一位博士Alistair McEwan已经获得行为医学研究所(Action Medical Research)的同意，为急救人员开发一种无线诊断系统来减少时间延误。感谢抗血栓药物，一些病人在病情发作的三个小时之内可以完全恢复。但出血也会导致中风。医生在治疗之前需要确定发病原因，因为不适当的服用抗血栓药物会加重损害。...[详细]
