KNP300JB-73-300R

Through Hole Resistors are components widely used on analog circuits and digital circuits. They are used to create resistance in the circuit and regulate current. KNP300JB-73-300R is one of the most common through hole resistors. Their application field and working principle deserves an introduction.

Application field

KNP300JB-73-300R is a through hole resistor with a resistance value of 300Ω. It is classified as a high power-type resistor, which makes it a great choice for high power circuits. Because its Resistance is not too big, it is also best for circuits with low current operating voltage. It can operate voltage from 0-12V DC, making it great for low power systems like RC cars, robots, and consumer electronics. It is also popular in various commercial, military and aerospace applications such as aircraft controllers, navigation systems, and radio communication systems.

Working Principle

KNP300JB-73-300R works based on a simple principle. It consists of a positive and negative terminal connected with a strip of metal, usually copper or nickel, which has a certain resistance. When current flows through this strip, it creates a voltage drop, resulting in a resistance to the flow of current. This resistance is the specified value of the resistor, in this case 300Ω.The resistors also have a tolerance rating, which means that their resistance can be up to a certain value higher or lower than their listed value. This tolerance range allows for more precise regulation of current in a circuit.In addition to the resistance value, KNP300JB-73-300R also have a power rating. This rating tells you how much power the resistor can handle before it overheats and fails. For KNP300JB-73-300R, it has a power rating of 1/4W, which means it can handle up to 250mW of power before it fails.Finally, KNP300JB-73-300R has an operating temperature rating of -45 to +200°C, which means it can operate reliably in temperatures from -45°C to +200°C. This allows for the usage of the resistor in different operating conditions.

In conclusion, KNP300JB-73-300R are excellent through hole resistors that can be used for high power circuits, low current operating voltage, commercial, military and aerospace applications, and various other applications. Their simple working principle makes them a reliable and efficient choice for your circuit designs.
