Through Hole Resistors

A Through Hole Resistor is a type of resistor which is inserted into a through-hole in a printed circuit board (PCB) for installation. They are designed to dissipate heat and provide an electrical connection between the two terminals. As their name implies, through-hole resistors are typically constructed with two contact leads that are inserted through the PCB. The leads are then soldered to the board, allowing for a secure connection.

The H819R6BZA is a through-hole resistor specifically designed for high temperature applications and are often used in automotive, aerospace, heavy-duty industrial, and other applications that require resistive loads to be dissipated at high temperatures. These types of resistors are also ideal for applications with harsh environmental conditions due to their high temperature and high reliability ratings.

Working Principle

The working principle of the H819R6BZA is fairly straightforward. At its core, it is a resistor with two terminals that are inserted through a hole in the PCB. When current passes through the resistor, a small amount of the current is lost due to resistance. This resistance creates a small amount of heat which is dissipated into the surrounding environment. This thermal dissipation is essential to prevent overheating and destruction of its components.

In order for the H819R6BZA to work as expected, its physical properties must remain unchanged despite its exposure to harsh environmental conditions. To ensure this, the resistor is equipped with a glass epoxy body which provides insulation and protection from environmental conditions. Additionally, the resistor is designed with high-temperature resistant leads. This ensures that the resistor can operate at high temperatures without damage and that its electrical performance remains optimal.

Application Field

As mentioned earlier, the H819R6BZA is commonly used in automotive, aerospace, heavy-duty industrial, and other high temperature applications. Due to its high temperature and high reliability ratings, the resistor can be used in a variety of harsh environment applications including ones that involve high voltage and high current. These include applications such as power supplies, electronic motors, and electrical heating elements.

The H819R6BZA is also suitable for applications that require precise control over the amount of current present in the circuit, as its resistance value can be precisely calculated. This can be especially beneficial for applications that are sensitive to current variations such as in electronic communications systems.
