脉冲承受能力
单脉冲图是每隔一分钟施加 50 个矩形脉冲的结果。可接受的极限是电阻从初始值的偏移小于 1%。施加的功率受所示允许脉冲电压图的限制。
连续脉冲
连续负载图是通过应用重复的矩形脉冲获得的，其中脉冲周期经过调整，使得电阻器中耗散的平均功率等于其在 70°C 时的额定功率。再次接受的极限是电阻从初始值的变化小于 1%。
频率行为
电阻器设计为根据欧姆定律工作。对于频率高达 100kHz 的电阻器来说，这基本上是正确的。在较高频率下，理想电阻器与线圈串联开关并与电容器并联开关对阻抗有额外贡献。电容和电感的值主要由终端尺寸和导电路径长度决定。
元件周围的环境对元件在印刷电路板上的行为有很大影响。
闪电浪涌
电阻器根据 IEC 60115-1 使用 1.2/50us 和 10/700us 脉冲波形进行测试。可接受的极限是电阻从初始值的偏移小于 0.5%。

The single impulse graph is the result of 50 impulses of rectangular shape applied at one-minute intervals. The limit of acceptance was a shift in resistance of less than 1% from the initial value. The power applied was subject to the restrictions of the maximum permissible impulse voltage graph shown.
The continuous load graph was obtained by applying repetitive rectangular pulses where the pulse period was adjusted so that the average power dissipated in the resistor was equal to its rated power at 70°C. Again the limit of acceptance was a shift in resistance of less than 1% from the initial value.
Resistors are designed to function according to ohmic laws. This is basically true of resistors for frequencies up to 100kHz. At higher frequencies, there is an additional contribution to the impedance by an ideal resistor switched in series with a coil and both switched parallel to a capacitor. The values of the capacitance and inductance are mainly determined by the dimensions of the terminations and the conductive path length.
The environment surrounding components has a large influence on the behavior of the component on the printed-circuit board.
Resistors are tested in accordance with IEC 60115-1 using both 1.2/50us and 10/700us pulse shapes. The limit of acceptance is a shift in resistance of less than 0.5% from the initial value.
