  • What is 'limiting element voltage'?
    • This is the voltage applied to the resistor, calculated from the rated power and resistance value. Generally, the greater the resistance value the larger the applied voltage.
      Therefore, the limiting element voltage is set to the maximum voltage that can be applied to the chip.
      The rated voltage will always be less than the voltage value obtained from the calculation.

  • How do you calculate the pulse current limit for chip resistors?
    • When a pulse exceeing the rated power is supplied, the pulse limiting power is considered the actual value.
      However, the guaranteed pulse power range consists of the rated power of each resistor, regardless of pulse time.
      Although the usability of final products is ultimately determined by the customer, if the actual waveforms of worrisome or potentially dangerous pulses are shared, ROHM can make recommendations to ensure safe operation.
