Through hole resistors are divided into two types: fixed resistors and adjustable resistors. H428RBDA application field and working principle are among the common types of fixed resistors. They are non-porous and usually have high thermal properties and low power dissipation.

H428RBDA is a kind of non-inductive resistor that usually has a four-terminal structure. The first and fourth pins provide the electrical connection between the two resistance legs, while the second and third terminals are often used to adjust the resistance value. As it is applied in a low-value range, it has an average power dissipation of less than 1 watt. This is a typical characteristic of a through-hole resistor.

The maximum static power rating of a H428RBDA is usually specified by the maker in watts. The resistive value is the difference between the resistance of the resistor and its nominal value. The temperature coefficient of a H428RBDA is usually larger than other through-hole resistors, which means that the resistance value increases or decreases as a function of temperature change. This allows for better temperature stability in applications.

The technology behind the H428RBDA’s design is based on magnetic technology, which provides the right balance between temperature stability, low power dissipation, and thermal conduction. It also has a wide range of operating temperatures so that it can be used in many different applications. The most common applications of the H428RBDA are in AC power electronics, and this is achieved by combining the predictable and stable resistance value with low power dissipation.

When the H428RBDA is used in a circuit, the voltage passes over the resistor instead of through it. This reduces the amount of electrical noise in the system, since the voltage applied to the resistor is not affected by any transient noise. This feature also ensures that the current flow is kept steady, eliminating the possibility of uncontrolled arcing.

The structure of the H428RBDA is also protected from external shock, which comes from sudden changes in current or voltage. This is done through the addition of a PTC thermistor, which disconnects the resistor in case of a sudden surge, and then reconnects it once the voltage is stabilised. This keeps any damage from occurring in the circuit.

In summary, H428RBDA application field and working principle prove it to be a very useful resistor in the power electronics industry. It provides predictable and stable resistance value with low power dissipation, and is protected against external shocks. Thanks to its good thermal properties it is also suitable for many different applications.
