Through Hole Resistors

A through-hole resistor is an electronic component used in circuits to resist the flow of electricity and provide electrical insulation between two points in a circuit. Though-hole resistors are typically cylindrical and have one or more holes drilled into their metal bodies. This type of resistor is also known as a thru-hole resistor or drill-hole resistor. Through-hole resistors are commonly used in high-power and precision applications due to their stability and consistent electrical characteristics.

For What Purposes Are Through Hole Resistors Used?

Through-hole resistors can be used in a variety of applications, including:

• Protection against overloads
• Power regulation and conditioning
• Impedance matching
• Signal smoothing and prevention of noise
• Providing isolation from voltage surges

43J120E Application Field and Working Principle

The 43J120E Through Hole Resistor is a surface mount resistors designed for power applications. These resistors are typically used in motor control applications, switch-mode power supplies, clamping, precision current sense and power sources. The 43J120E resistor has a maximum power rating of 100 Watts with a low temperature coefficient of 0.015%.

The working principle of the 43J120E through-hole resistor is simple. It is a fixed resistors in the sense that its resistance does not vary with current and voltage. When current runs through it, a voltage drop is produced and this voltage drop across the resistor is related to the resistance value of the component.

In applications such as motor control, this voltage drop can be used to control the speed or position of the motor. The resistor is also used in switch-mode power supplies and clamping applications to control the amount of current that passes in the circuit. It can also be used in precision current sense applications to sense current changes and adjust the power source accordingly.
