Through Hole Resistors

Through hole resistors, also known as leaded resistors, are a type of resistor used in electronic circuit boards. The name comes from the fact that the electrical connections to the resistor are made by passing electrical wires through a hole in the resistor body. This is in contrast to surface mount resistors which are soldered directly to a printed circuit board (PCB). Through hole resistors offer advantages such as ease of replacement and higher power ratings compared to their surface mount counterparts. The disadvantage of through hole resistors is that they take up significantly more space on a PCB, which can limit the number of components on a board or require the use of larger boards.

The H85K62DZA is an example of a through hole resistor. This type of resistor is typically used in regulated power supplies and circuits which require high-precision voltage regulation. The H85K62DZA resistor has a power rating of 15 Watts. This resistor also has a maximum operating voltage of 1500V and a maximum surge voltage of 3000V.

The working principle of a through hole resistor is based on Ohm\'s law. According to Ohm\'s law, the voltage across a resistor is proportional to the current flowing through it. The resistance of the resistor determines the amount of current that can flow through it. When the voltage across a resistor is increased, the current through it will also increase. By adjusting the resistance of the resistor, the amount of current flowing through it can be adjusted, thereby controlling the voltage across it.

The H85K62DZA resistor has an operating temperature range of -55°C to +155°C. It is sealed in a metal can which helps to reduce noise levels and prevent contamination. The metal can also provides ESD protection. The resistor also has high power levels, low noise levels, and high reliability, making it suitable for use in power supplies and other high-powered applications.

The H85K62DZA is one example of a through hole resistor. By understanding its application field and working principle, as well as the advantages and disadvantages of through hole resistors, it is possible to select the appropriate resistor for a given application. Through hole resistors are useful in applications which require high power ratings, high reliability, and good noise reduction, and they are often used in regulated power supplies and high precision circuits.
