Through Hole Resistors

A through hole resistor, also known as a Resistor-Network with non-isolated leads, is an electrical component used to reduce the current flowing in an electrical circuit. Through hole resistors are most commonly utilized in printed circuit boards for power applications and can be used as both static and dynamic resistors.

RNX0381G00KNR7 is a through hole resistor designed for use on PCBs in power applications. It is a discrete component that is by far one of the most important pieces of electronic components. This resistor has a power rating of 0.25 Watts and a resistance range between 0 Ohms and 100K Ohms. It is made from a metal oxide film and the contact surface is gold-plated.

RNX0381G00KNR7 Application Fields & Working Principle

RNX0381G00KNR7 can be used in a wide range of applications such as medical equipment, power supplies, and instrumentation control systems. It can also be used as a temperature sensor or over-current protection in electronics applications.

The working principle of RNX0381G00KNR7 relies on Ohm\'s Law. This law states that voltage, current, and resistance are related according to the equation V=IR, where V is the voltage measured across the resistor, I is the current that flows through it, and R is the resistance. As the current through the resistor increases, the voltage across it also increases. This relationship can be exploited to limit the current in a circuit.

The resistor also has the property of self-heating, which is when its resistance increases with temperature. A small amount of heat will be generated in the resistor, which is why it is important to choose a resistor with a power rating that is suitable for the application. Additionally, resistors should not be over-driven as they can be badly damaged if over-heated.

RNX0381G00KNR7 can provide a wide variety of resistive values and is designed to be stable over time. Additionally, it can handle extremely high frequencies due to its metal oxide film structure. It is a reliable and durable resistor, and can be used in harsh environments.
