Through Hole Resistors

A through hole resistor is an electronic component that is designed to reduce current flow in a circuit. It is usually mounted on an insulated, non-metallic, printed circuit board (PCB), and is connected to a terminal block for connection to other components in a circuit. Through hole resistors provide an effective and low cost solution for regulating current in electronic circuits. The working principle of a through hole resistor is fairly straightforward and can be easily understood.

H428R7BCA application field and working principle

The H428R7BCA through hole resistor, as a water-resistant type of fixed resistance component, is mainly used in various fields such as audio-visual equipment, automotive electronics, communication and computers, as well as in applications such as motors, AC/DC converters, power supplies and frequency converters.

The working principle of a through hole resistor is based on a basic physical concept called Ohm\'s Law which states that voltage, or voltage drop, is directly proportional to the current passing through a given resistance. According to Ohm\'s Law, the current through a resistor is proportional to the voltage across it. The resistance value of the resistor determines how much of the current is allowed to pass. If the current is too great for the resistor, it will overheat, reducing its ability to function effectively as a part of the circuit.

The H428R7BCA through hole resistor is used to reduce the electrical current in a circuit and is designed to operate in areas exposed to moisture and other environmental conditions. The resistor has a carbon-film wound around a high-quality ceramic body that provides increased thermal resistance. This feature extends the life of the resistor when subjected to high temperatures. The resistor also features an insulation system of epoxy, polyimide, teflon, and mica to further protect it from moisture and other environmental conditions.

For applications requiring greater current, larger power or higher voltage ratings, other through hole resistors can be used. These resistors can be formed into large networks to provide a high-density current limiting solution for use in heavy industrial applications such as conveyors, welding and metalworking equipment. The higher the overall network size, the greater the number of current passes can be managed.

Through hole resistors are available in a variety of sizes and concentrations for applications requiring high performance and stability. They are durable and reliable components suitable for a range of applications, providing precision control of current flows in circuits. The H428R7BCA through hole resistor is a cost effective and reliable solution for applications where current limiting and resistance are needed, while offering improved safety and longer life.
