Through Hole Resistors play a very important role in various electronic appliances, from enabling functionality to helping ensure safety. The H862RFZA is one such resistor, which features a low temperature coefficient and no affected by soldering heat that allows for greater versatility and ease of use. In this article, we’ll take a look at the application field and working principle of the H862RFZA.
Application Field
The H862RFZA typically functions as a current limiting resistor in high current applications, particularly those where there may be spikes or other fluctuations in the current. As it has a low temperature coefficient and is not affected by soldering heat, it is also a reliable resistor for use in temperature related applications. The H862RFZA can also be used as a voltage-dividing, feedback, damping or bleeder resistor as well as a voltage source or reference. It is commonly found in automotive systems, high speed telecommunications, industrial automation, and radio frequency (RF) applications as its size and shape allow these resistors to be placed in tight spaces.
Working Principle
The working principle of the H862RFZA is made possible due to the materials used in its construction. The resistor element is made of a metal film which is deposited onto a ceramic performance which has an insulated coating and is printed with a smudge-proof circuit layer. The two contacts are held together by an epoxy-filled chip, which is surrounded by a metal heat shield, providing better temperature control and a greater degree of thermal stability. This combination provides excellent protection against temperature changes, spikes, and other brief current fluctuations.
When an electric current is applied, the heat produced by resistance causes an increase in the temperature of the resistor. The metal heat shield dissipates the heat produced by the current to the surrounding environment, minimizing the amount of heat transfer to the outside of the resistor, cooling both the resistor body and the area surrounding the resistor.
The resistance of the film is determined by its width, length and thickness, all of which can be precisely controlled and adjusted in order to get a precise resistance value. Combined with its temperature coefficient and thermal stability, the H862RFZA is capable of providing reliable and stable performance in a wide variety of applications.
In conclusion, the H862RFZA is a powerful and reliable resistor suited for a wide variety of applications. Its small size, temperature coefficients and thermal stability make it a great choice for the likes of automotive systems, telecommunication, and industrial automation applications.
