Through Hole Resistors

A through hole resistor (FMP100FRE52-475R) is an electronic component that is made up of a wire or strip of resistance material that can limit or regulate the flow of electrical current in an electric circuit. The through hole resistors are generally small and can be used in a variety of applications and assemblies.

The primary function of through hole resistors is to control and determine the amount of current going through the circuit. This can be done by increasing or decreasing the total amount of resistance along the entire wire or strip. The resistor can also be used to protect other components in the circuit against receiving an overload of current.

Specific to this type of resistor, the FMP100FRE52-475R is a commercially available four-pin surface mount resistor, where two of the pins are connected to the resistance material, and two are connected to the circuit ground. It is rated for up to 100 volts, and can handle up to 4.75 watts of power with an accuracy of ±1%.

Application Fields

Since through hole resistors are generally small and can be used in a variety of application and assemblies they are most commonly used in current sensing and feedback circuits, audio applications, impedance matching, noise reduction networks, protection circuits, voltage dividers, and nearly any other kind of general-purpose application in which a variable or fixed resistor is needed.

In the case of the FMP100FRE52-475R, it is recommended for use in audio applications where its high current rating of 4.75 watts and accuracy rating of ±1% can be put to good use. Other applications for the FMP100FRE52-475R include high power filters, power electronics, motor drives, digital circuitry, AC/DC power supplies, Transformers, telecom circuits, and switching power supplies.

Working Principle

The working principle of through hole resistors is based on Ohm\'s Law, which states that the current flowing through a conductor between two points is directly proportional to the potential difference across the two points. This means that if the voltage is increased, the current will also increase, and that if the resistance is increased, the current will decrease.

In a through hole resistor, the two terminal pins are connected to a resistor element of a specific resistance value. When a voltage is applied across these terminals, a current will flow through the resistor, and the amount of current will be determined by the resistance value of the resistor.

For the FMP100FRE52-475R, this means that when a voltage of up to 100 volts is applied across the two terminals, a current will flow through the 4.75-watt rated resistor which is determined by its resistance. The accuracy of the resistor is then determined by the ±1% tolerance rating, meaning that the current will not exceed the set value by more than 1%.

Conclusion

Through hole resistors are an essential component in a variety of electrical circuits and assemblies. The FMP100FRE52-475R is a four-pin surface-mount resistor that is rated for up to 100 volts and can handle up to 4.75 watts of power, with an accuracy of ±1%. It is used in a variety of applications where its high current and accuracy rating can be put to good use, such as audio applications, high power filters, motor drives, AC/DC power supplies, switching power supplies, and more.

The working principle of through hole resistors is based on Ohm\'s Law, which states that the current flowing through a conductor between two points is directly proportional to the potential difference across the two points. The FMP100FRE52-475R is then designed so that when a voltage of up to 100 volts is applied across the two terminals, a current will flow through the 4.75-watt rated resistor which is determined by its resistance value.
