Through Hole Resistors

Resistors are electronic components that resist changes in electric current. They are mostly applied in circuits to modify current flow, accept hues, and create voltage drops. Through-hole resistor, also called leaded resistor, is an axial resistor that has two lead-out wires, one on each side of the resistor body. This kind of resistor is usually put in printed circuit boards(PCBs) with drawn holes in which the leads of the resistors can be connected and mounted. The H82K5BYA type through-hole resistor is a fixed-value resistor combined with 5W power rating and 50 ppm/k tolerance. It has two round wires that are anchored into the base and two external leads that project out for easy connection. It has an extended range of resistance values up to 1 G ohm with 6-digit coded values. It has a thick film chip technology that enables the resistor to offer superior stability and reliability. The outer shell of the resistor has ceramic material that can provide stable mechanica and thermal properties, and better environmental protection and performance. What is especially unique about the H82K5BYA is that it is one of the few over-temperature rated through-hole resistors. It has a wide operating temperature range of -55°C to +155°C, and has a higher thermal time constant of 0.7 RC to reduce thermal time-constant errors. Additionally, the resistor is heat tolerant and is able to dissipating up to maximum of five watts, which is two watts more than the average through-hole resistor. Its excellent temperature stability and power rating make it well suited for analog applications such as buffers, line drivers, and power supplies. The H82K5BYA achieves its stable performance is by using a special low-density metal resistive element. This element is formed through a unique manufacturing process involving multiple layers of thin film. It gives the H82K5BYA a stable resistance and low temperature coefficient. Additionally, this resistor has a great voltage range of 3-6 volts so it can be used in different circumstances.The working principle of the H82K5BYA is simple but efficient. The resistor works by limiting the current flow through the circuit. It does this by using the Ohm’s law, which states that the current is inversely proportional to the resistance. That means that higher resistances result in lower current flow. This ability to control current is one of the most important functions of a resistor and it is necessary for many circuits. Its low temperature coefficient also makes it very useful for analog circuits. In conclusion, the H82K5BYA through-hole resistor offers an excellent combination of features that make it useful for a wide range of applications. It has a wide resistance range and a high temperature rating. Its heat tolerance makes it suitable for use in power supplies and other high-power applications, while its good thermal time constant makes it perfect for analog applications. Its low-density metal resistive element ensures stable and reliable performance. All these features make it a great choice for many applications and make it an excellent alternative to other through-hole resistors.
