Through Hole Resistors

H8178KDYA is a type of through hole resistor, which is a two pole component with resistance value, used to limit or adjust electric current level in electrical circuits. It is one of the most common components used in electronic circuit design. Different types of through hole resistors exist, varying both in construction and in their usage. This article will discuss both the application field and working principle of H8178KDYA.

H8178KDYA is composed of two layers of metal film integrated together, creating a uniform resistive back plane. The top layer of metal film is insulated from the bottom layer by a non-conductive plate. To adjust the current level passing through, the resistance of the top layer of the plate can be adjusted by means of external taps.

H8178KDYA has a wide range of applications, including automotive electronics, consumer electronics, telecommunications, aviation electronics, and medical electronics. For example, in automotive electronics, H8178KDYA is used to inhibit the current flowing to electric motors or to lighten the current level of headlights, stereo systems, and air conditioning systems. It is also used in consumer electronics, such as in TV sets, computer monitors, and mobile phones. In telecommunications, H8178KDYA is used to limit signal levels and to provide impedance matching.

The working principle of H8178KDYA is relatively simple. In its simplest configuration, it has a top and bottom resistor layer with multiple taps in between. When a current is passed through the resistor, it passes through the bottom layer of the resistor first. As the resistance of the top layer of the resistor is adjustable, the current is then able to be limited or adjusted to the desired level.

The top layer provides the majority of the resistance, while the bottom layer provides a path for the current to flow. This type of resistor has the advantage of having a low power dissipation rate, and its construction also provides improved reliability. Furthermore, it is also more readily assembled onto a circuit board than other types of resistors.

In summary, H8178KDYA is a type of through hole resistor that is used to limit or adjust current level in electrical circuits. It is composed of two layers of metal film integrated together, creating a uniform resistive plane. Its wide range of applications includes automotive electronics, consumer electronics, telecommunications, aviation electronics, and medical electronics. The working principle of H8178KDYA involves a top and bottom resistor layer with multiple taps in between. When a current is passed through the resistor, it passes through the bottom layer first and the resistance of the top layer can be adjusted to limit or adjust the current level.
