Through Hole Resistors are some of the most essential components in electrical and electronic circuits. Using resistors in circuits to control current flow or to adjust signal levels is key in controlling the functioning of electrical and electronic components. The H82K74BZA is a Through Hole Resistor that is widely used in many circuits. This article will discuss the application field and working principle of the H82K74BZA.

The H82K74BZA is a fixed Through Hole Resistor with a power rating of 1/4 watt (W) and a tolerance of ± 5%. It is a ceramic coated package size 0.1” x 0.4” (2.54mm x 10.16mm) with a lead spacing of 0.1” (2.54mm). It has a resistance range of 10Ω to 22 mΩ and a temperature coefficient (TC) of ±200 ppm/°C, meaning it can handle temperatures up to 212 °F (100 °C). Due to its compact design, the H82K74BZA is suitable for high-density circuit board layouts.

The H82K74BZA Through Hole Resistor has wide applications, ranging from analog to digital circuits. In analog circuits, the resistor can be used as a current limiter, to control charge and discharge in capacitors, or as snubber networks. In digital circuits, the resistor is commonly used as a pull-up or pull-down resistor, a voltage divider, or an oscillator. In motor control applications, the H82K74BZA is often used for phase shifters. In telecommunications systems, the resistor is used as an attenuator for passband and stopband filtering. In power management systems, the resistor is used to set current levels and build voltage regulators. The H82K74BZA is also widely used in consumer electronics, medical devices, automotive systems, industrial environments, and more.

The working principle of an H82K74BZA Through Hole Resistor is based on the property of resistance. Resistance is a phenomenon that occurs in materials when an electrical signal passes through them. The electrical signal causes collisions between the electrons in the material, and the energy from these collisions is dissipated as heat. The amount of resistance encountered in a given material depends on the type of material and the number of collisions it causes. The H82K74BZA has a low resistance value which helps reduce the amount of power lost in the circuit. The resistor also has a high temperature coefficient, meaning it can handle temperatures up to 212 °F (100 °C).

In conclusion, the H82K74BZA Through Hole Resistor is a fixed resistor with a power rating of 1/4 watt and a tolerance of ± 5%. It has a wide range of applications in analog and digital circuits, motor control systems, telecommunications systems, and power management systems. The working principle of the H82K74BZA is based on the property of resistance. The resistor\'s low resistance and high temperature coefficient enable it to efficiently control current flow and voltage levels in circuits.
