Introduction to Through Hole Resistors

Through Hole Resistors are a type of passive component used in electronic circuits. They are used to reduce or control the amount of current flowing in a circuit. This can be done by lowering the voltage, limiting the amount of current flowing through the circuit, or by providing a predictable amount of resistance. A resistor can also be used in a circuit to provide a specific amount of resistance to a signal or load.Through hole resistors are available in different sizes with various resistance levels. They can be used in terms of their electrical characteristics such as the I^2R power dissipation, power resistance ratio, thermal resistance ratio, noise and tolerance, operating temperature and response time. They can also be physically divided up into three types: axial-leaded resistors, radial-leaded resistors, or disk-shaped resistors.

H8143RBCA application field and working principle

The H8143RBCA Through Hole Resistor is a carbon-based, radial-leaded, through hole-type, metal oxide resistor. It is constructed with three distinct elements: a cylindrical carbon pellet core, HEX resistive encoding for code recognition, and a metal coating with insulation wrap. The carbon pellet core is the primary element responsible for providing the value of resistance.The H8143RBCA Through Hole Resistor has an operating temperature range between -25°C and +125°C with a tolerance rating of ±10%. It provides a maximum voltage rating of 300V, a maximum working voltage of 250V, and a rated power dissipation of 0.25W. The HEX resistive encoding is used to provide a unique code for each resistance value. This is done by coding the resistance value into three distinct segments. Every segment has four different values, from 0 to 7, that represent the resistance based on its value.The metal coating has two distinct purposes: to provide resistance to oxidation and to provide electrical insulation. The metal coating also provides protection for the carbon pellet core, ensuring that the electrical characteristics remain consistent. Additionally, an insulation wrap is applied over the metal coating to provide further electrical insulation.The H8143RBCA Through Hole Resistor is designed for a wide range of applications, including Power supplies, Communication systems, Automotive electronics, Aerospace systems, and Medical devices. It is also widely used in industrial equipment, computer systems, consumer electronics, and switches.The H8143RBCA Through Hole Resistor is a reliable, precision resistor component that provides a consistent and reliable resistance value over its operating range. It is designed to provide consistent and reliable electrical characteristics, enduring extreme temperatures, and withstanding harsh environments.In conclusion, the H8143RBCA Through Hole Resistor is used in a variety of industries and applications due to its reliability, accuracy, and durability. Its resistance values are accurately and reliably encoded in a HEX resistive code and its electrical characteristics are consistently maintained with a metal coating and an insulation wrap. This makes it the ideal resistor for power supplies, communication systems, automotive electronics, aerospace systems, and medical devices.
