The MBx/SMA resistor series can handle up to 5 kV for the MBE0414 size with resistance values above 5 kΩ. For the MBB0207 size, this resistor series offers 1.2/50 µs lighting strike pulse load capability up to 3 kV for resistance values above 10 kΩ. This pulse load specification considers a maximum permissible resistance change lower than 0.5% after the resistor is exposed to five pulses with twelve-second intervals.
