Through Hole Resistors

Through hole resistors are built in a cylindrical housed through which a wire can pass. They are usually used to reduce current flow, increase voltage drop, divide two voltages, or to bias active elements. The most popular and common type of through hole resistors are the KNP3WSJR-73-68R series.

These resistors are constructed with a metal oxide coating on a ceramic rod. The coating replaces the need for a carbon element, providing greater power dissipation, greater operating temperature stability, and greater resistance stability. It also reduces unwanted noise and better shields against external electromagnetic interference. The cylinder is then filled with a non-corrosive, dielectric epoxy to provide additional protection and improve heat dissipation.

Application Field

KNP3WSJR-73-68Rthrough hole resistors are used in a wide range of applications in electrical and electronic engineering, such as in radio and television sets, audio amplifiers, and in many other types of audio-visual equipment. They are also used in computer-aided design and automated office systems, or even in RF instrumentation systems. These resistors are widely used in quality control systems, circuit protection and interference reduction, and signal conditioning applications.

Working Principle

The working principle of KNP3WSJR-73-68R through hole resistors is quite simple. The ceramic rod is coated with a metal oxide and scored to form grids which allow electricity to travel through it. The grids attenuate the amount of current passing through the resistor while still allowing enough to reach the desired electronics. The resistor\'s composition and construction allows it to handle higher wattages and to dissipate heat far more effectively than most other resistor-type components.

These through hole resistors also exhibit highly stable operation which is a big factor when it comes to reliability. Since the conductor surfaces are separated by solid insulation and the whole resistor is filled with a non-corrosive epoxy, KNP3WSJR-73-68R resistors can last a long time with little deterioration. This means that repairs or replacements would be very rare.

KNP3WSJR-73-68R through hole resistors are commonly used in the majority of electrical and electronic designs. They offer high performance, a wide range of power levels, excellent durability and long life. With such features, KNP3WSJR-73-68R series resistors are definitely one of the best choices for any application.
