Through Hole Resistors

Through hole resistors, also known as thru-hole resistors, are a type of electronic component used to provide electrical resistance in a circuit. A resistor is a passive two-terminal electrical component that resists the flow of current. Resistor values are usually expressed in ohms, kilohms, or megohms. The H478R7BDA is a through hole resistor designed for use in circuits requiring moderate power dissipation. It employs metal oxide film resistors and is sealed in a two-pin package with a nickel-plated copper base and two 18mm plastic pins. The H478R7BDA has a wide range of application fields where it is used to limit current or voltage in a circuit, provide bias to active devices, or even isolate signals from each other. It can also be used in a host of other applications, such as linear regulators, voltage regulators, motor drivers, and more. The working principle of the H478R7BDA is based on the resistance of the component. It is a two-terminal device whose resistance reduces with increasing current through it. When a voltage is applied to the two terminals, a current will flow through the resistor, producing a given power. The resistance of the resistor limits the current in proportion to the voltage. The current is inversely proportional to the voltage, and is also affected by the temperature of the device. The H478R7BDA provides reliable performance in circuits requiring moderate amounts of power. It has a power rating of ½ Watt at 25°C ambient temperature, as well as a tolerance of ± 5%. It also features a wide range of operating temperatures, up to 85°C. It is also RoHS compliant and easily meets the requirements of most common certification standards. The H478R7BDA has a compact design, making it ideal for use in cramped spaces. It is lightweight and easy to install, and can be used in a variety of circuits, from analog to digital. It is also widely used in DIY projects and hobbyists, who find its small size and flexible temperature range ideal for their projects. In conclusion, the H478R7BDA through hole resistor is a reliable and versatile component that can be used in a variety of applications. It is easy to install, lightweight, and has a wide range of power ratings and temperature resistance ranges. Its small size and reliable performance make it a popular choice for hobbyists and engineers alike.
