Through Hole Resistors are electronic components that can limit current or provide a voltage reference in electronic circuits. KNP200JR-52-20R, as an example of Through Hole Resistors, has a wide application field and working principle.

Application Field

KNP200JR-52-20R is a general-purpose low-power resistor (P = 0.2 W), which is used in many electronic circuits such as electronic toys, automotive electronics, industrial electronic equipment, and communication devices. It can be used for voltage division, current limitation, signal attenuation. It is also used in college teaching and experiment circuits.

Working Principle

Through Hole Resistors possesses a pair of electrodes through which current passes when connected to a voltage source. The voltage applied to the two end-points of the resistor determines the amount of current that passes through it. The resistance is equal to the ratio between the voltage applied to the two end-points of the resistor. That is, the resistance is equal to the ratio of the applied voltage over the current flow. Thus, by adjusting the resistance of the resistor, the current that is allowed to flow through it can be regulated.

KNP200JR-52-20R resistor is composed of a metal strip sandwiched between two semi-conducting materials. When the voltage in the terminals of the resistor increases, the current passing through the resistor increases. This is because the resistance in the resistor decreases as the voltage applied across it increases which allows more current to flow through it. When the voltage decreases, the current also decreases.

KNP200JR-52-20R resistor works on a principle of thermal voltage dissipation. The higher the current flowing through the resistor, the higher the heat produced by it, resulting in a decrease in its resistance. This effect is used to protect electronic circuits by dissipating excess current away from the components. This resistor has a good ability to dissipate heat and can withstand temperatures of up to 250 degree Celcius.

Conclusion

KNP200JR-52-20R is an example of Through Hole Resistors, and is widely used in many application fields. It is used to regulate the current and voltage in electronic circuits. It also helps provide a constant voltage reference in electronic circuits. Furthermore, it works on a principle of thermal voltage dissipation and has a good ability to dissipate heat.
