Introduction to Through Hole Resistors

Through Hole Resistors are components that are used for reducing circuit current without returning the energy back to the power source and also to prevent overloading of the circuit and equipment. Through Hole Resistors are attached directly to the circuit board, mounted in 2 or 3 leads and are available in different shapes, sizes and wattages. They are used in many electrical and electronic applications, from communications systems to industrial equipment and appliances.

Types of Through Hole Resistors

Through Hole Resistors are available in both fixed-value resistors and adjustable values. Fixed value resistors are commonly used in high voltage applications. They are generally made from carbon, resistance wire, metal foil, film, and ceramic material. They range in resistance from 10 ohms to 100 kilohms and up to 20 megohms depending on the application.Through Hole Resistors are also classified by wattage. Power rated resistors have higher wattage because they are used in applications with higher power levels. The wattage and temperature ratings vary from 1/8 watt to 20 watts and 25 to 350 degrees Celsius. Low power resistors are usually specified with a wide range of wattage ratings and with the help of hardware, custom-built heat sinks are used.

KNP3WSJB-52-130R Application Field and Working Principle

KNP3WSJB-52-130R is a 3 watt Through Hole Resistor. This Through Hole Resistor is made up of an alloy film on a ceramic substrate and a metal alloy film, which is used to create a resistive elements of different powers. The dissipation of heat emitted by the resistor depends on size, composition, and configuration of the resistors.KNP3WSJB-52-130R has wide application field, such as electronic controllers, industrial automation, medical equipment, wired internet, unmanned aerial vehicles, solar energy storage and DC motor drivers. KNP3WSJB-52-130R working principle is based on Ohm\'s Law. When AC current passes through a resistor, it will cause heating due to the transfer of energy in the form of heat. The electrical energy is converted to thermal energy, which causes the resistor to dissipate some of the energy. The energy is determined by the value of resistance, the current applied, and the temperature of the resistor. Generally,KNP3WSJB-52-130R is suitable for general electronic applications where a Through Hole Resistor is needed. It is capable of handling higher wattage than other types of resistors, making it ideal for high-power applications.

Factors to consider when selecting a Through Hole Resistor

Selecting a Through Hole Resistor is dependent on the application and the desired end result. When selecting a Through Hole Resistor, several factors should be considered, such as resistance value, voltage rating, temperature rating, wattage rating, and type of resistor.The resistance should be chosen based on the current, voltage or power requirements of the application. The voltage rating must be higher than the peak voltage expected in the circuit. The temperature rating must be higher than the environmental temperature where the resistor will be mounted. The wattage rating should be greater than the wattage the resistor will be exposed to. And lastly, the type of resistor should match the application such as a high-power resistor or a precision resistor.

Conclusion

Through Hole Resistors are essential components that can be used for a variety of applications including power conditioning, signal processing and power amplification. KNP3WSJB-52-130R is one type of Through Hole Resistor which can handle higher wattage than other resistors, making it ideal for high-power applications. When selecting a Through Hole Resistor, several factors should be taken into consideration to achieve desired results.
