Through Hole Resistors - Application Field and Working Principle

Through Hole Resistors, often referred to as THRs, are widely used in a variety of electronics applications. The most common application is in providing a variable amount of resistance to a circuit. These components can also be used in other applications, such as voltage stabilization and frequency compensation.

The THR model number, MBA02040C8874FRP00, describes its features. This includes its size (0204 is a 4mm x 5mm package); its resistance value (in this case 8.8kΩ); the tolerance of the value (+/- 7%); the wattage rating (0.4W); and the temperature coefficient (±50ppm/°C).

The resistance value of a through hole resistor will vary depending on the temperature and current it is exposed to. The resistor\'s temperature coefficient will determine the rate at which this variation takes place. The temperature coefficient of the aforementioned THR is ±50ppm/°C, which means that it will change 0.05% in resistance for every one degree Celsius change in temperature.

The electrical characteristics and properties of a Through Hole Resistor are determined by the construction of the device. It is made up of a resistor strip, which is folded in a U shape and the two ends of the resistor are connected together with a lead wire. This lead wire is surrounded by an insulating coating or housing. The housing defines the size and wattage of the THR, and can include multiple resistors in one package.

The electrical resistance of a THR is formed by electrically connecting the resistor strip to a terminal lead in the package. The resistance value is marked along the resistor strip itself and can be measured directly by inserting a multimeter probe into the lead. The resistance value of a THR can also be measured indirect, by applying a voltage across its leads and measuring the resulting current flow.

The primary applications of Through Hole Resistors include voltage and current regulation, frequency compensation, temperature compensation, voltage level shifting, and current sensing. These components may also be used as a voltage divider, and can provide a predictable resistive load for circuits. In addition, THRs are commonly used for controlling the supply voltage for computer processors and other digital circuits.

In summary, MBA02040C8874FRP00 Through Hole Resistors are a versatile type of resistor that can be used for a number of applications. They offer excellent tolerance, temperature coefficient, and stability, and their small size makes them an ideal choice for use in tight spaces. The THR also offers a predictable resistance value, which makes it easier to measure and control the current or voltage in a circuit.
