Through Hole Resistors

A through hole resistor, also known as a through-hole resistor, is a small cylindrical electronic component that has two electrodes mounted on opposite faces. It has a wide range of applications and is commonly used to provide electrical resistance in electronic circuits. The H8787KBDA is one such through-hole resistor. This article will discuss the application field and working principle of the H8787KBDA.

Applications of the H8787KBDA

The H8787KBDA through-hole resistor is mainly used in automotive applications. It is often used to provide a calibrated reference voltage to spark plug leads for fuel injector pulse control. It is also used to provide voltage reference for ease of circuit calibration and data acquisition. The H8787KBDA is also used in a variety of other automotive applications such as providing power steering current sensing and providing temperature compensation for oxygen sensor measurements.

Working Principle of the H8787KBDA

The H8787KBDA is a two-terminal device that is connected in series with an electrical circuit. When electrical current flows through the resistor, electrical energy is dissipated in the form of heat. This energy is proportional to the square of the current flowing through the resistor. This means that, as the current increases, the amount of heat dissipated also increases. The resistor acts as a voltage divider and reduces the voltage to the desired level. The resistor has a known resistance value and this resistance determines the voltage output of the resistor.

The resistor is composed of a metal tube that is filled with an inert gas. The metal tube is provided with electrical contacts at each end to allow for electrical connection. Inside the tube, two inner conductors are mounted. The inner conductors are insulated and surrounded by a metal oxide layer which gives the resistor its unique shape. The resistance of the resistor is determined by the thickness and composition of the metal oxide layer. As the voltage across the resistor changes, the thickness of the metal oxide layer also changes, which in turn changes the resistance of the resistor.

The resistor is a highly reliable and robust component that can withstand harsh environments and has a wide range of operating temperatures. It is also very compact and has a low profile, which makes it ideal for use in automotive applications. The H8787KBDA through-hole resistor is an excellent choice for automotive applications where a reliable and accurate voltage reference is needed.
