Working Principle

The KNP500JB-91-4R3 works by reducing the amount of current that can pass through it. It creates a resistance that is determined by its length and width. When a voltage is applied across it, the current that is allowed to pass is a fraction of the applied voltage. The amount of the current reduction is determined by the ohm value of the resistor and the amount of voltage applied to it. The resistor also has a maximum amount of voltage that it can withstand before it is damaged, which is known as the working voltage of the resistor. It is important to ensure that the applied voltage does not exceed the working voltage of the resistor, otherwise it could be damaged.
