Through Hole Resistors

Through hole resistors are an important type of electrical device used to control current levels in electronic circuits. They come in all shapes and sizes, from the large-scale members of the TH-2 family to the smallest, chip-sized package of the B3500. But no matter the size or application, each type utilizes two main components: a metal or ceramic substrate and resistive material. The most common components are carbon or wire wound resistors.

HVR3700009104FR500 Application Field and Working Principle

The HVR3700009104FR500 is a unique, through-hole resistor which is suitable for a variety of applications. It is small, typically measuring 7.55 mm x 2.7 mm, and can be used for applications with limited space or reliability requirements. The resistor utilizes a specialized type of carbon composition substrate-resistant material which allows for superior accuracy in controlling current levels.

The resistor is designed to handle direct current (DC) levels between 0 and 500 volts, as well as current levels up to 5 amperes. It is capable of tolerating a steady state temperature of up to 200°C and a temperature coefficient of resistance (TCR) of ±250 parts per million. The accuracy of results achieved by using this resistor is extremely reliable, and it also produces a low harmonic current and noise level.

The working principle of the HVR3700009104FR500 is based on the flow of electrons through the substrate material. When electricity flows through this material, electrons are repelled from one plate and attracted to the other. This resistance creates a restraint on the current flow, and the voltage drops as a result. The material used in the substrate as well as the size of the resistor both determine the resistance value of the device.

The HVR3700009104FR500 is typically used in audio components for frequency regulation and voltage regulation, as well as industrial production machinery which requires precise regulation of current. The device is also suitable for use in medical instruments and in any application where tight control of current levels is needed. Additionally, it is commonly used in automotive electronics.

In summary, the HVR3700009104FR500 is an accurate, reliable, and durable through-hole resistor which is suitable for a variety of applications. Its metal or ceramic substrate and resistant material allow it to handle direct current levels of up to 500 volts, with a promising TCR of ±250 parts per million. It is most commonly used for frequency and voltage regulation in audio components, medical instruments, and other applications where precise current levels are required.
