Through Hole Resistors are electronic components used to provide an electrical resistance to a circuit path. The WW12FT8R87 is a popular through-hole resistor model, and it can be used in many applications. Here, we will look at the application field and working principle of the WW12FT8R87.

Application field

The WW12FT8R87 is a 12W metal-clad oxide-coated resistor. It is designed for use in power circuits and is rated for operation up to 600VDC or 400VAC. It is suitable for use in power supply and lighting applications and can be used as a shunt resistor or for motor speed control. It is also suitable for use in a variety of high-voltage applications where a large resistance value is needed.

The WW12FT8R87 offers a resistance range of 200 ohms to 100k ohms, making it suitable for a wide range of applications. It can be used to control current or voltage, as well as in noise suppression circuits, rectifiers, motors, solenoids, relays, power supply circuity, and various other electronic devices.

The WW12FT8R87 has a wide thermal range, making it suitable for use in industrial and commercial applications. It is also available in a variety of physical sizes and mounting styles, such as vertical, horizontal, surface mount, and through-hole mounting styles. This makes it ideal for converting a device\'s signal or energy from one form to another.

Working Principle

The WW12FT8R87 is an electrically conductive resistor that works by converting electrical energy into heat energy. When a current is applied to the resistor, the electrons flowing through it will collide with the atoms of the resistor material, causing them to vibrate and producing heat. The resistance of the resistor is dependent on the number of collisions per second and the temperature of the resistor.

The resistance of a resistor will also vary with temperature. When the temperature of the resistor increases, the number of collisions per second increases and the resistance of the resistor decreases. Conversely, when the temperature of the resistor decreases, the number of collisions per second decreases and the resistance of the resistor increases. As a result, the resistance of the resistor will remain relatively constant over a wide range of temperatures.

The WW12FT8R87 is a non-inductive resistor, meaning that it does not generate a magnetic field when operated at a constant current. This makes it well-suited for applications where a magnetic field would be undesirable, such as in EMI (electromagnetic interference) suppression or in medical applications such as pacemakers.

The WW12FT8R87 is a robust and reliable resistor that has proven itself in many applications. It is available in a variety of size, power rating, and resistance range so that it can be utilized in a variety of power and control applications. In addition, its non-inductivity makes it suitable for many sensitive applications.
