H4P20KFZA

Through Hole Resistors are electronic components which have electrical resistance and can be used to change the shape of an electrical signal. As such, they are often used to control the flow of current and voltage in a circuit.

The H4P20KFZA is an example of these types of components and it offers a very high degree of heat dissipation and thermal stability. The H4P20KFZA is a surface mount resistors in a TO-247 Through Hole package, and it provides a higher power dissipation than resistors in small surface mount packages.

Application Field

H4P20KFZA can be used in applications such as switching power supplies, industrial switching power supplies, automotive circuits and medical devices. Its higher power dissipation provides protection against indirect damage caused by overvoltage/overcurrent events. It also provides higher insulation resistance.

Working Principle

The working principle of the H4P20KFZA is based on Ohm’s law, which states that the current in a circuit is proportional to the applied voltage. This is the basis of resistance. The current is the total voltage divided by the total resistance. The H4P20KFZA uses an internal resistor to control the flow of current by controlling the voltage.

The internal resistor itself consists of an element that has a relatively low resistance across its length, but that increases dramatically when a voltage is applied across its ends. This property allows the device to act as a variable resistor, allowing the current through the device to be controlled by varying the voltage applied across it.

The H4P20KFZA is designed to provide a high degree of thermal stability and heat dissipation. This is achieved by using a highly heat-resistant material such as ceramic, which has a low coefficient of thermal expansion and is able to withstand extreme temperatures. A ceramic body is also used to isolate the internal resistor from external elements, thus minimising interference from external components.

The H4P20KFZA is a Through Hole component, meaning it is connected to other elements in the circuit by being soldered on. By doing this, a secure connection is created for the resistor, allowing it to be moved and adjusted in a circuit without needing to be physically or electrically disconnected.

The H4P20KFZA is a reliable and efficient way of controlling the flow of current and voltage in a circuit. As it is a Through Hole component, it is easy to install and maintain in a circuit. Its high power dissipation ability provides greater protection against overvoltage/overcurrent events and its thermal stability makes it suitable for high-temperature applications.
