Through Hole Resistors: VM3JB62R0 Application Field and Working Principle

Through hole resistors are one of the most common and basic electronic components used in electrical circuits and systems. They can be used for power control, voltage and current limiting, signal filtering, and protection from overvoltage and overloads. As a kind of resistor, the VM3JB62R0 (also referred to simply as “VM3”) is a three-terminal resistor with a 2-inch package that can be used in a variety of applications due to its maximum resistance of 6.2 ohms, relatively large power rating at 1/2 watt, and improved temperature coefficient over regular carbon film resistors. It is widely used in various industrial, commercial, and consumer circuits, often in filtered and frequency limiting applications.

Physical Description

The VM3JB62R0 is a three-terminal resistor made with a metal oxide substrate and screen printed resistor elements. The leads are inserted through the board and then soldered into place on the underside of the board, making them easy to mount and replace if necessary. The VM3 measures about 20mm by 15mm, making it relatively large compared to other types of resistors. This makes it especially useful for high-power applications, since it can dissipate more heat than smaller resistors and is less prone to heating and electrical noise.

Application Fields

The VM3JB62R0 is used in a wide variety of electrical applications such as consumer, industrial, and military. It is often used in applications that require a certain level of resistance due to its relatively large power rating. Some of the most common applications for the VM3 include power supplies, voltage regulators, motor control circuits, wave shaping circuits, protection circuits, noise filters, and current limiting circuits. Other specific applications include automobile electronics, security systems, industrial controllers, and telecommunication equipment.

Working Principle

The working principle of the VM3JB62R0 is quite simple. When a voltage is applied to one of the two terminals, current flows through the resistor and is dissipated as heat. The amount of current determined by the resistance of the resistor, which is preset at 6.2 ohms. As voltage is applied to the terminals, the resistor absorbs the voltage, thus reducing the total voltage across the terminals and limiting the amount of current that can flow through the circuit. The VM3 can also be used to filter out unwanted frequencies, or to prevent overvoltage and overload conditions.

Advantages and Disadvantages

The VM3JB62R0 offers several advantages over other types of resistors, namely its large size, large power rating, and improved temperature coefficient which allows it to remain relatively stable over a wider temperature range. Its large size also makes it good for high-power applications, which require larger resistors that can handle more heat. The main disadvantage of the VM3 is that it is relatively expensive compared to other resistors, and can be difficult to replace if it fails.

Conclusion

The VM3JB62R0 through hole resistor is a three-terminal resistor with a maximum resistance of 6.2 ohms, a relatively large power rating of 1/2 watt, and an improved temperature coefficient. It is commonly used in a variety of applications, including filtering, motor control, protection circuits, and current limiting. The VM3 is relatively expensive compared to other resistors, but its large size and improved performance make it ideal for high-power applications.
