Through Hole Resistors

Through hole resistors are electronic components that reduce the flow of electric current through a circuit. They are typically composed of a semiconductive material, which is usually ceramic, metal or a combination of metals. Through hole resistors are an essential component in the circuitry of any electronic device.

H4221RBZA Application Field and Working Principle

H4221RBZA is a through hole resistor featuring a robust metal construction and a 4.7K ohms resistance at 25V working voltage. It is designed to operate reliably in the temperature range of -20°C to +125°C, providing dependable and stable performance while still delivering high accuracy measurements and reliable operation. A H4221RBZA resistor is typically used in high-end audio equipment, digital home appliances, automotive systems, RF devices, and other similar applications.

The working principle behind a H4221RBZA resistor is simple. When voltage is applied to the resistor, it creates a electrical field that is proportional to the resistance value. This electrical field resists the flow of current from one point to the other, depending on the resistance value. Higher resistance results in higher resistance to current flow, while lower resistance allows more current to pass through.

The resistor body itself is composed of a semiconductive material, which is usually ceramic or metal. This material reacts to the electrical field created when voltage is applied and acts as a resistance, forming what is called a resistive path. This resistive path has a certain amount of resistance that depends on the number of turns the resistor has. The more turns the resistor has, the higher the resistance value, and the less current will be able to pass through.

H4221RBZA resistors are usually available in a range of resistance values, from 1.8K ohms to 470K ohms. These values are typically manufactured in increments of 10, making them easy to find in nearly any application. Additionally, H4221RBZA through hole resistors are also available in a range of package sizes, from 0302 to 1206.

In summary, H4221RBZA through hole resistors are highly reliable, accurate and dependable components used in a wide variety of electronic devices. These devices provide a stable and reliable performance in the temperature range of -20°C to +125°C, with a resistance range of 1.8K ohms to 470K ohms and package sizes from 0302 to 1206.
