Through Hole Resistors are among the most widely used types of resistors in power electronics applications. The H828K7DCA is a special type of through-hole resistor developed to cater to the needs of modern power applications. It is characterized by a high power rating, precision temperature coefficient, enhanced thermal performance, and low heat dissipation.

The H828K7DCA resistor is a two-terminal device designed for handling high temperatures up to 150°C. The resistor body is made of a metal alloy mix combined with catalytic passivation or heat resistant glass. Its body material is strong and rigid enough to ensure a long life span. The resistor is also designed for high-temperature use and it has a unique foot shape that allows for firm and reliable mounting. In addition, it also includes built-in heat sinks that shore up stability and reliability.

The resistor has a wide application field and it performs well in power electronics operations such as load carrying, voltage dividing, and phase control. It can also be used as a current limiter in power circuits. The H828K7DCA resistor is ideal for switching power supplies, motor control, power supplies, and DC-DC converters.

The working principle of the H828K7DCA resistor is quite simple. It consists of a temperature-stable metal alloy, which acts as a resistor, and a glass-fused coating that acts as insulation. The resistance value of the resistor is determined by its length and diameter. The standard length and diameter of the resistor depend on the operating environment and can vary between 4mm and 90mm. This range of sizes enables it to handle different power ratings according to the application of the power unit.

The resistor works by reducing the amount of current flowing through it. Its resistance is set to a certain value, which is determined by its length and diameter, and the resulting current in the circuit is proportional to the amount of resistance offered by the resistor. This current reduction works by dissipating some excess energy as heat. This heat is dissipated from the resistor to the environment.

The H828K7DCA resistor defines a new standard in high power resistors. It provides a high power rating, precision temperature coefficient and low heat dissipation. This wide range of features make it an ideal choice for many operations. It is ideal for improving power efficiency, reducing EMI noise, stabilizing power supplies and preventing overvoltage situations.
