Through Hole Resistors

Through Hole Resistors, sometimes also known as Through-Hole Technology, or THT, is a type of electrical component that is used to provide resistance within an electronic circuit. By manipulating the resistance value of a resistor, an electrical current can be directed and reduced to the desired level for the exact operation of a circuit or device. PWR220T-35-47R0F is a Through Hole Resistor used for various electronic applications, and this article will examine its application field and working principle.

The PWR220T-35-47R0F is a Through Hole Resistor that is designed to fit various printed circuit board (PCB) layouts on surface mounted circuit boards. It is a low resistance, axial type resistor that features a two watt power rating, and can be used in high voltage applications such as motor control systems, television receivers, home appliances, and other related products requiring power dissipation. As an axial type resistor, it also has a small form factor and can easily be integrated into smaller components or PCBs.

The application field of the PWR220T-35-47R0F is vast, and it can be used in a variety of applications such as voltage regulation in computer equipment, power supplies, and motor controls; providing surge protection for automotive components; and providing shorting protection in integrated circuit (IC) chipsets. The resistor also has a wide range of resistance values, ranging from 10 ohms to 100 thousand ohms, giving it a high level of versatility. Furthermore, due to its two watt power rating, the PWR220T-35-47R0F can provide reliable power dissipation in high-temperature environments.

The working principle of the PWR220T-35-47R0F is based upon the well-known law of Ohm’s Law, which states that the current flowing through a resistor is inversely proportional to its resistance value. As the resistance of the resistor increases, the current decreases. The PWR220T-35-47R0F, as an axial resistor, has an internal resistance element that is surrounded by an insulation layer. To create resistance, the internal resistor is composed of a number of metal layers that have been thinned out or “sliced” so that their resistance can be measured accurately. As electricity passes through these “slices” of metal, the electrons literally “bump” into the metal layers, creating a resistance. Thus, the higher the resistance of the PWR220T-35-47R0F, the lower the current allowed to flow through it, and consequently, the less power it needs to output to achieve the same desired effect.

In conclusion, the PWR220T-35-47R0F Through Hole Resistor is a versatile component used in many applications and can be used to provide effortless power dissipation. Its two watt power rating and wide range of resistance values make it an ideal choice for a number of applications, and its form factor and internal design make it an efficient component for a number of PCB designs.
