Through Hole Resistor WW2JB2K20 Aplication Field And Working Principle

Through hole resistors, commonly known as THRs, are a type of resistor that have been in use in the electronics industry for more than 100 years. THRs come in a wide variety of sizes and shapes and can be used in almost any application where resistance to current flow is required.The WW2JB2K20 THR is one such resistor with an unusually high power rating of 0.75 watts. These THRs have a ceramic body for durability and are particularly suitable for surface-mount applications. The large size makes them ideal for applications where large resistors are required without having to increase the size of the printed circuit board.WW2JB2K20 application fields include high power and precision resistor applications in automotive, industrial, medical, and audio/video systems where a wide range of ohmic values is needed. The WW2JB2K20 THR is suitable for both mains and low-voltage AC work, and can also be used for some DC applications as well.When it comes to using a THR, the basic principle is to add a resistor between the two current-carrying conductors and thus reduce the current being passed between them. The current passing through the resistor creates a voltage drop, and thus reduces the voltage at the end of the resistor.This voltage drop depends on the resistance of the resistor, as well as the current passing through it, and can be calculated using Ohm’s law. This voltage drop can be used to control the current passed through the resistor and is the basis of resistance-controlled circuits.The resistance of a resistor is usually indicated in ohms, and this is the case for the WW2JB2K20 THR too. The WW2JB2K20 THR is available in a wide range of resistance values, from 0.5 ohms to 20 kohms, making it ideal for applications where precision is needed or a wide range of resistance values is required.The WW2JB2K20 THR is also rated for an operating temperature range of -55 to +125 deg C and a thermal resistance of 53 C/W, making it suitable for use in high-temperature installations where a high level of dissipation is needed. Additionally, the WW2JB2K20 THR is UL recognised, so it can be used in UL recognised equipment with confidence.In summary, the WW2JB2K20 THR is a high-power, precision THR with a wide range of resistance values and is suitable for many applications. Its ability to handle high temperature installation with a high level of dissipation, as well as being UL recognised, makes it an ideal choice for a variety of industrial, automotive, medical and audio/video applications.
