KNP2WSJR-73-2R7 is one of the types of through hole resistors. The resistor consists of a capacitor connected on its terminals with an insulating material. Its application field is mainly for resistive-membrane applications, wherein the resistor forms a barrier between the two terminals, minimising the electrical leakage from one capacitor to another.The resistor works in two essential ways. First, the resistor blocks the direct current (DC) from travelling according to the resistance value implanted in resistors, which is also known as its ‘resistance’. It limits the flow or current and protects the circuit from drastic changes, which can cause the circuit to malfunction.Second, the resistor helps to dissipate the amount of energy stored on the capacitor. This process is known as voltage dropping. This way, the amount of potential difference between two terminals of the resistor can be limited down to an approved value.There are several working principles involved in the operation of a through hole resistor, including the infinite solutions of resistor networks and the concept of power dissipation. A resistor network is composed of one or more resistors connected in a series or parallel configurations, and each of them provides its own resistance value against the current. This network uses simulation software calculations and supports the exact formulas of resistance to determine the voltage drop and pick current values in the circuit.On the other hand, the concept of power dissipation involves the following: when the voltage across the resistor is greater than the rated voltage, then the Power that needs to be dissipated by the resistor is proportional to the square of voltages. KNP2WSJR-73-2R7 resistors have very high temperature coefficient, allowing them to be used in high load applications. This type of resistor has a low inductance, enabling very fast switching time. Furthermore, the resistor has very low ohmic value compared to wire-wound resistors and it has excellent accuracy. Its design has a small body size that allows the user to design very compact applications. It also has a wide operating temperature range from -55 to +155 degree Celsius, enabling the device to operate at extreme temperatures. The resistor features very low power loss and thus, is suitable for applications that require more heat dissipation. Finally, the resistor is exceptionally durable, making it a great choice for long-term projects. In most cases, the KNP2WSJR-73-2R7 through hole resistor is used in application such as automotive, consumer electronics, wireless, telecom, and medical device applications. For example, it is widely used for automotive designs, such as in engine control systems, Driver Assistance Systems (DAS) and Instrumentation & Control (I&C) systems. It is also used in consumer applications such as safety circuits in consumer products. Moreover, it is used in wireless applications, such as in communication transceivers and antennas. The resistor is also used in telecom applications, such as in telecom infrastructure devices, optical networks, and subscribers’ routers. Finally, the resistor finds application in medical devices, such as in hearing aids, pacemakers and other medical devices.In conclusion, KNP2WSJR-73-2R7 through hole resistors are widely used in various applications, ranging from automotive designs to consumer electronics, wireless, telecom and medical device applications. It features very low ohmic values, high temperature coefficient and excellent accuracy, making it a great choice for designs requiring more heat dissipation. It is also very durable, enabling users to use it in long-term projects.
