• Resistors

Resistors have a "rated voltage" determined by their rated power and resistance value. Basically, voltages exceeding this rated voltage cannot be applied, but for pulses and surges, manufacturers may specify allowable ranges. Our company has established regulations such as "maximum overload voltage → short-term overload specification of 2.5 seconds" and "one pulse → specification for one pulse of less than 1 second," allowing usage that exceeds the rated voltage if conditions are met. This document explains the pulse usage judgment flowchart for "one pulse" and "repetitive pulses," as well as the underlying concepts and specific examples. Please take a moment to read it.

The difference between current detection and shunt... Originally, each has a different meaning and usage, but in reality, they are now used interchangeably to refer to the same functions or products, and there are no clear definitions or classifications in terms of product specifications or structure. "Current detection/shunt resistors" are used for purposes such as voltage control, overcurrent limitation, and battery level detection. We provide a clear introduction to the operating principles and characteristics of resistors by using diagrams and tables.
