Through Hole Resistors

Through hole resistors are a type of resistor commonly used on circuit boards that act as a form of current flow controller. They can be made with a variety of different materials, including copper, aluminum, and steel. They are typically made in an axial or radial configuration, though they are also available in a surface mount configuration. The resistance value is set when the resistor is manufactured and can range from a few ohms to thousands of ohms. The current rating of a particular resistor is determined by the size and material used.

KNP700JB-91-1R2 is a kind of through hole resistor. It is a high-precision, low-temperature coefficient resistor manufactured using a special low-resistance material. The resistor is composed of four layers of dielectric material, with an internal resistor element made from a non-conductive ceramic. The resistor is coated with an insulating layer and is followed by an outer coating, making the resistor resistant to moisture and other contaminants.

KNP700JB-91-1R2 Application Field

KNP700JB-91-1R2 is suitable for various applications such as:

• Power supplies: The KNP700JB-91-1R2 can be used in DC-DC converters, AC-DC converters and other power conversion circuits for temperature compensated power supplies.
• Medical applications: The resistor is suitable for use in medical electronic devices such as EKG machines and patient monitors.
• Industrial control systems: The resistor is suitable for use in programmable logic controllers, motors, and relays.
• Instrumentation: The resistor is suitable for use in instrumentation circuits such as process control systems, instrumentation amplifiers and servo amplifiers.

KNP700JB-91-1R2 is also ideal for use in high frequency designs, thanks to its low-temperature coefficient and stable performance.

KNP700JB-91-1R2 Working Principle

The internal resistor element is an important component of the KNP700JB-91-1R2 that is responsible for setting the resistance value of the particular model. It is composed of a non-conductive ceramic material that has been specially supplemented with resistive material for a fixed current-limiting resistance. The outer layer is a shaped ceramic material that is responsible for providing the desired insulation resistance. The ceramic is then coated with a thin metal layer which is necessary to provide voltage-spark resistance.

The outer layer also consists of a tin layer that is intended to provide maximum protection against dust, moisture, and other hostile environmental factors. The tin layer also acts as an additional conductor for efficient heat transfer, thus further increasing the stability of the resistor\'s performance.

KNP700JB-91-1R2 is a very reliable and stable resistor, thanks to its low-temperature coefficient, stable performance, and high-precision resistor elements. It is also very simple to mount and replace. This makes the through-hole resistor an ideal choice for many applications.
