Through Hole Resistors are essential components of electrical and electronic circuits. They serve to limit current, set voltage levels, divide or adjust voltage levels, as well as dampen oscillation. One example of a through-hole resistor is the WW12JTR220. This component is common for applications in audio-frequency circuits, industrial process control, and test equipment.

The WW12JTR220 is specially designed to resist high frequency interference and has a low propagation delay. It also features a wide operating voltage and temperature range. In most cases, the device may be mounted in any orientation without affecting performance. The component also has a small physical profile, allowing it to be used in space-constrained applications.

The working principle of the WW12JTR220 is based on the principles of thermionic emission, or thermionic current. This process occurs when electrons in a heated conductor gain enough energy to escape from the conductor and flow towards a cooler region. This process of electron flow forms an electrical current. The device utilizes this electrical current to limit current flow in a circuit.

The device consists of a two-wire resistive element and a thermionic cathode. When a voltage is applied to the thermionic cathode, electrons are ejected from the device and become part of the electrical current flow. The two-wire resistive element is then used to limit the current flow. This current flow is controlled by the resistance of the element and the applied voltage.

The WW12JTR220 is a precision thermionic resistor with a wide range of applications. It is useful in audio-frequency circuits, for industrial process control, and in test equipment. It offers a wide operating temperature and voltage range, providing flexible solutions for many applications. Its thermionic emission based principles ensure it is a reliable and efficient resistance device.
