Built to provide electrical power, through hole resistors like the WW12FT324R are an integral part of many current technologies. Whether powering a telephone link, pneumatic control system, or providing impedance matching in audio and video systems, this application of resistors continues to prove itself useful in our modern power distribution systems.

The WW12FT324R is an Through Hole Resistor that offers a maximum power rating of 5 Watts and utilizes a lead-through post that has ceramic sealing. The device also boasts a power tolerance of ±25%, a temperature coefficient of ±100ppm/°C, and a power dissipation of 5 Watts. In addition, the resistor features four terminals which are arranged in a rectangular piece of phospher bronze that is 0.8 mm thick. Essentially, these components are designed to bear high voltage and high temperature which allows them to be utilized in many industrial, electrical, and mechanical purposes.

The WW12FT324R’s most important application field is in signal conditioning and signal isolation. A common use of the WW12FT324R is in electrical motor speed controllers. This is because the device has a high resistance which can help maintain the desired speed of the motor by providing a steady current. Due to the nature of electrical motors, it is essential that the current supplied is steady and consistent in order for the motor to function properly.

Likewise, the WW12FT324R is well suited for use in audio and video systems, as well as electronic power electronics as it has a high power dissipation and low temperature coefficient. This allows it to meet the stringent requirements for impedance matching in these applications. Additionally, the WW12FT324R is used in pneumatic control systems where electrical power is required to establish and maintain a desired pressure within a system.

Now, let’s examine the working principle of the WW12FT324R. The device acts as a variable resistor within an electrical circuit. Electrical current flows through the resistor, and depending on the voltage and current of the incoming signal, the resistor will allow a controlled portion of the current to pass through. This current passing through has the potential to create heat, and as the temperature rises, this resistance increases too. Therefore, if the voltage and current of the incoming signal changes, then the resistor will automatically resist the current to make sure that the required power level is maintained within the circuit.

This is achieved through the ceramic posts. These act as insulators and help to reduce the ambient heat that the resistor experiences. Ceramic is well known for its ability to withstand high temperatures and it helps to ensure that the resistor is able to cope with the changing temperatures of the circuit. In addition to the ceramic posts, the WW12FT324R also includes a terminal that is posted on either the top or bottom of the resistor. This allows for easy installation, and makes it perfect for short circuit protection.

In summary, the WW12FT324R provides an invaluable service in many applications due to its wide range of applications and its efficient working principle. By providing a variable resistance, the device is able to maintain the necessary power within a circuit while at the same time keeping it from overheating. Furthermore, the device’s ceramic posts make it suitable for high temperature applications, while its posted terminals make for easy installation. Ultimately, the WW12FT324R is an important component of many current technologies such as pneumatic control systems, audio-video systems, and electrical motor speed controllers.
