Through Hole Resistors are an essential component in the modern electronics industry. The KNP500JB-91-1R3 is a through hole resistor specifically designed to provide high-power and temperature stability in demanding applications.

The KNP500JB-91-1R3 is an aluminized nickel barrier resistor for use in high voltage, high temperature, and high frequency power applications. It is capable of withstanding up to 10 kilovolts AC bias at temperatures up to 125°C, and deliver up to 250 watts power dissipation. Its precision tolerance up to ±5%, ensures excellent stability and accuracy in applications such as lighting, welding, and power factor correction.

The KNP500JB-91-1R3 employs a construction design that is resistant to moisture and other corrosive elements, allowing it to be safely used in many wet and hazardous environments. This makes it ideal for applications such as off-shore power control systems, outdoor LED signage, and emergency lighting systems. Its UL94V-1 insulation material also ensures that it meets the most stringent safety requirements for power components.

The KNP500JB-91-1R3 is also available with a ceramic endcap which is temperature stabilized and increases the thermal resistance of the unit. This is an excellent choice for applications that require extended high temperature operation, and provides the user with peace of mind due to its ability to protect against accidental over-heating. Additionally, the KNP500JB-91-1R3 is UL recognized and carries a five-year warranty.

The working principle of the KNP500JB-91-1R3 is based on the electrical resistance principles of aluminized nickel barrier resistors. It works by passing an electric current through the resistor which transforms some of the energy into heat. This causes the resistor to increase in temperature and will cause the resistor to reduce or increase resistance accordingly. This change in resistance is used to regulate the electric current in the circuit, helping to ensure that circuitry remains within the expected range and therefore avoiding any potential overloading or malfunctioning due to excessive current.

The KNP500JB-91-1R3 is a reliable and durable through-hole resistor, and is ideally suited for use in a variety of applications in the electronics and power industries. Its high-power and precision tolerance capabilities, as well as its UL recognition and five-year warranty, make it an excellent choice for any power application.
