Through Hole Resistors

20J18RE application field and working principle

Through-hole resistors are widely used in many different applications. These components can be used in circuit boards, temperature sensors, LED lighting, power electronics, signal circuits, and even in laser applications. Some specific types of the through-hole resistors are used in transformers, microwave ovens, timers, and thermistors.

The 20J18RE resistor, or 18 ohm resistor, is one of the most commonly used through-hole resistors in the world. This type of through-hole resistor is available in common half watt sizes and can handle a maximum power of three watts without failure. The 20J18RE also has a low resistance value, which makes it perfect for use in LED lighting, power electronics, and precision voltage regulation applications.

The 20J18RE is similar to other through-hole resistors in its construction. The component consists of two electrodes connected by a thin metal film. The electrodes are made from an electrically conductive material such as copper, tin-nickel or silver. The metal film acts as an electrical insulator and is very thin, usually measuring about one hundredth of a millimetre thick. This insulating layer prevents leakage current from flowing between the two electrodes.

These components also come with various pin configurations, such as single or dual contact lead design. In single contact lead design, the component is soldered into a printed circuit board by connecting one lead directly to the board. Dual contact lead design involves soldering two leads into the board, thus creating an insulated section between the two leads. This type of configuration is often used in applications where an increase in current is required to successfully power a given circuit.

The 20J18RE works by reducing the amount of electricity that passes through it. When a voltage is applied to the resistors, it acts as a barrier to electricity, reducing the current that flows through the circuit. The amount of electricity that passes through depends on the resistor\'s resistance value. Higher resistance values will reduce the current flow more, while lower resistance values will allow more current to pass through.

The 20J18RE also has distinct temperature characteristic curves. The resistance of the resistor changes as the temperature changes. This feature can be useful in applications that require precise temperature control. As the temperature of the environment surrounding the resistor increases, it will reduce the amount of current that can flow, thereby maintaining a stable temperature inside the application.

The 20J18RE resistor is an essential component for many electronic systems. It is especially useful in controlling and regulating power circuits. Its flexibility, stability, and low resistance values make it a great choice for a variety of applications. Through-hole resistors like the 20J18RE are a reliable, cost-effective, and easy-to-use solution for applications that rely on precise power regulation.
