Through Hole Resistors

Through hole resistors (THRs) are the most common type of resistors in electronic circuits. In electronic circuits, THRs are used to limit current, reduce voltage, control signal levels, and provide bias to components. They come in a variety of shapes and sizes, and the material used for the construction of the resistor will determine its resistance and the temperature coefficient of its resistance.

H4187RBDA Application Field and Working Principle

H4187RBDA through hole resistors are primarily used in the automotive industry. These resistors are characterized by their high-temperature stability and low-temperature coefficient of resistance. The resistors are constructed from a high-temperature-resistant material such as Alumina-Silicon-Carbide (ASC). The ASC construction of the resistor ensures long life expectancy, even in the most extreme temperature conditions.

The working principle of the H4187RBDA THR is very simple. The resistor is composed of two leads, one of which is connected to one end of the resistor, while the other is connected to the opposite end. When a current passes through the resistor, a voltage drop is created across the resistor. This voltage drop is proportional to the current passed through the resistor, and as such is used to control current flow in electronic circuits.

The H4187RBDA resistors are rated for operation in temperatures from -55oC to +150oC. They are typically used in automotive applications such as Oxygen Sensor control, ABS control, ECU control, powertrain control, and fuel system control.

The resistor’s construction makes it ideal for high-temperature and harsh environment applications. The ASC construction of the resistor ensures that the resistor is highly resistant to high-temperature fluctuations. The resistor is also highly resistant to thermal shock as it is designed to handle large fluctuations in temperature without any loss in resistive qualities.

The resistor is also highly reliable and resistant to vibration and shock. This makes the H4187RBDA THR very suitable for use in automotive electrical systems, where it is exposed to a high level of vibration and shock on a daily basis.

The H4187RBDA resistor has a wide range of applications in the automotive industry due to its high-temperature stability, low-temperature coefficient of resistance, and reliable construction. It is used in numerous automotive applications, such as Oxygen Sensor control, ABS control, ECU control, powertrain control, and fuel system control. The THRs are also highly reliable and resistant to vibration and shock, making them very suitable for use in automotive electrical systems. The wide range of automotive applications that the H4187RBDA THRs are used for makes them an important component in the automotive industry.
