Introduction to the Application Field and Working Principle of Through Hole Resistors

Through hole resistors are one of the most common passive electronic components founds in a wide variety of electronics. They are used to reduce and control current charges, voltage and signal levels. The most common application of Through Hole Resistors is in the form of FMF1WSFRF52-15R.

History of Through Hole Resistors

Through hole resistors have been around since the late 1960s and since then, have become increasingly popular among manufacturers and engineers. The first through hole resistors were made of a ceramic material with a wire attached to the center and two pins on the sides. This design was suitable for getting an accurate resistance over a large range and for providing stability and uniformity over the entire resistive range. From the 1960s to the present day, the design and usage of through hole resistors has progressively evolved. Manufacturers have sought to increase the accuracy and stability of the resistors, as well as to boost their power ratings and manufacturing processes. For example, they have developed resistors with an adjustable resistance, allowing for wider range of resistance. They have also discovered new materials, such as carbon film and metal-oxide film, which further allows for finer accuracy and power ratings.

Features of Through Hole Resistors

Through hole resistors are designed to handle both high and low power levels. This has become a popular choice among many designers and engineers that use through hole resistors as the current, voltage or signal levels of their circuit design need to be regulated. They come in various shapes, sizes, power ratings and with different types of terminations. Common types of terminations include Wire-Wrap, Press-Fit, Crimped and Bent Lead. Through hole resistors are often red, blue or green and their resistive values are often shown in a four-digit code on the body of their package. They also come in a wide range of resistance values from a few Ohms to megohms and much higher. This makes them suitable for almost any electronic design application.

Usage of Through Hole Resistors

Through hole resistors are often used for current, voltage or signal control. Their main function is to reduce electrical current or to regulate signal attenuation. They are also used for voltage and current circuitry design, including current splitting, limiting current and capacitor discharge. They can also be used for decoupling, signal isolation, wave shaping, signal storage and thermal compensation. They are also used in power supplies, load banks, rectifiers, amplifiers, and oscillators.

Types of Through Hole Resistors

The different types of Through Hole Resistors include Wire-Wrap, Press-Fit, Crimped and Bent Lead. Each type of resistor has its own advantages and limitations. The Wire-Wrap type is a thick wire that has a resistance value inscribed around it. This type of resistor is often used in high power applications as the insulation of the wire helps to dissipate the heat that is generated during operation. Press-Fit resistors have a termination that is attached to the body of the resistor. This type of resistor is often used for circuits where the connections are not exposed to harsh environments. Crimped resistors have a crimped termination on the body of the resistor. This type of resistor is often advantageous because the crimped termination makes for a more secure connection. They are commonly used in circuits where the body of the resistor may be exposed to harsh environments. Finally, Bent Lead resistors are similar to crimped resistors but have a bent lead instead of a crimped termination. Bent Lead resistors are often used in circuits where the body of the resistor may be exposed to extremely harsh environments.

Working Principle of Through Hole Resistors

The working principle of Through Hole resistors is based on Ohm’s law. That is, the resistance of a resistor is inversely proportional to the current flow through it. Hence, when the current increases, the resistance decreases and when the current decreases, the resistance increases. The amount of resistance of a through hole resistor is also dependant on three factors. These factors include the resistive material, the number of turns in the resistor, and the value of the resistive material used. More specifically, the resistance of a through hole resistor is determined by the following equation : R = k * (N/L) ^Swhere R is the resistance, k is the resistivity of the resistive material, N is the number of turns, and L is the length of the resistive material.

Advantages and Disadvantages of Through Hole Resistors

The advantages of Through Hole Resistors are that they are cheap, durable, and easy to manufacture. They also have non-linear characteristics, meaning that they can be used for power regulation and current splitting. Additionally, their resistance value can be easily adjusted by changing the number of turns.On the downside, they can not handle extremely high temperatures. Although they will not be damaged by high temperatures, their performance may be reduced.

Conclusion

Through Hole Resistors are one of the most common and widely used resistors in the electronics industry. With the advancement in technology, their accuracy and stability has continuously improved. They are typically used for current limit, voltage reduction or signal level control and come in various shapes, sizes, and power ratings. They work based on Ohm’s law, making the resistance inversely proportional to the current flow. Finally, they come with their own sets of advantages and disadvantages.
