Through Hole Resistors

Through-hole resistors are a type of resistor used in electrical circuits. They are among the most common and widely used components in all types of electrical and electronic circuits. The through-hole version of the resistor is the most basic, having a simple cylindrical shape with leads that can be inserted into a printed circuit board (PCB).

KNP2WSJB-73-220R Application Field and Working Principle

The KNP2WSJB-73-220R is a Through Hole Resistor designed for general-purpose applications. It is widely used in audio, automotive, military and industrial applications. It can be used as a direct replacement for other hole type resistors, such as wire-wound and film resistors, and can also increasingly be used instead of surface mount resistors in some applications. It has a wide operating temperature range of -55°C to +125°C, a high current rating of up to 6.3A, and a power rating up to 390mW.

The KNP2WSJB-73-220R is designed to work in either a single-resistor, two-resistor, three-resistor, or a four-resistor circuit. It is available in two types of packages: a two-pin 0.2" x 0.2" x 0.6" or a four-pin 0.2” x 0.2” x 0.8”. Each package includes a central resistor and two or four lead pins. The pins are connected to the resistor through a layer of insulation.

The KNP2WSJB-73-220R resistor works by reducing the amount of current flowing through a circuit. It does this through the use of the resistor’s resistance, which is determined by its manufacturing materials and construction. The resistance will usually range from a few hundred ohms to 6.3A. The resistor works by using the principle of Ohm’s Law, which states that the current through a conductor is directly proportional to the voltage applied across it. The resistor acts as a kind of “speed bump” for current, slowing it down so that the desired amount of current can be delivered to the receiving device.

The KNP2WSJB-73-220R is commonly used for power supply, signal and switching applications, including power protection, voltage regulation, test and measurement, and audio equipment. The resistor is also used in automotive circuits, such as those for engine control modules, as well as in military and aerospace applications. Due to its wide range of temperature tolerance, the KNP2WSJB-73-220R is also suitable for use in extreme environmental conditions such as high-temperature automotive and aerospace applications.

In conclusion, the KNP2WSJB-73-220R is a Through Hole Resistor designed for a variety of general-purpose applications. Its wide operating temperature range, high current rating, and power rating make it ideal for use in extreme environments. The resistor works by reducing the amount of current flowing through a circuit, using the principle of Ohm’s Law. Common applications include power protection, voltage regulation, test and measurement, and audio equipment, as well as automotive and military applications.
