Through Hole Resistors are one of the most basic components in any electronic circuit. A resistor is an electrical component that limits or regulates the flow of electric current by offering resistance to the passage of current. They are used as a protective device, as current control, noise reduction, and voltage regulation. There are various types of resistors depending on the application, one type being the H4P22RFZA Through Hole Resistor.

The H4P22RFZA Through Hole Resistor is a power resistor with a power package suitable for through hole mounting. It is available in a range of sizes, with both traditional and modern terminals and connection methods. It can handle high power up to 250 W, with resistance capabilities from 0.1 ohm to 2M ohms. The H4P22RFZA has a heat dissipation of up to 18W, a power resistance tolerance of ±1%, and a thermal resistance of 5.15° C/W (at 100° C). It is designed to have a long life and is suitable for many applications.

The main application of the H4P22RFZA through hole resistor is in power electronic equipment, such as high power generators, frequency converters, and inrush current measurement equipment. It is also used in power supply AC reactors, LED Lighting, electric power switches, contactors, power supply regulators, and high current transformers. Other common applications include dc/dc converters, brushless motor drives, welding equipment, boilers, laser cutting machines, and lightning protection systems.

The working principle of the H4P22RFZA Through Hole Resistor is based on the “Ohm’s law”, which states that the current flowing through a conductor is inversely proportional to the resistance of the conductor. In other words, a higher resistance will cause less current to flow. This is why the H4P22RFZA has a high power rating and offers effective resistance and current control. When a current is sent through the resistor the heat generated is dissipated through the heat sink provided with the component.

The H4P22RFZA Through Hole Resistor is a reliable and cost effective component able to handle high power and offer effective resistance and current control for a variety of applications. It is also very easy to install due to its through hole mounting method. Its long life and high heat dissipation are also desirable features for many users.
