Through Hole Resistors

A through hole resistor, such as the HHV1WSJR-73-120K, is a component used to regulate the flow of electric current in a circuit. It can be used to slow down the flow of electricity, to adjust the voltage in a circuit, or to control how much current electricity can pass through a component. Through hole resistors are made of ceramic, metal, carbon, or film, and are used in many applications, such as in circuit boards and in various electronics.

The working principle of a through hole resistor is relatively simple. Electric current enters one end of the resistor and the current pressure inside the resistor is balanced by a resistance value, which is usually expressed in ohms. The total electrical resistance of a through hole resistor equals the combination of the specific resistance of the resistor material plus the contact resistance at the solder joints. Depending on the specific resistor, the resistance may vary as the temperature or voltage changes.

Through hole resistors are available in different housings, which will determine the size of the resistor and its electrical performance. The HHV1WSJR-73-120K is a SMD chip resistors, which is a surface mounted device, meaning that it is installed on the top surface of a circuit board. It is used in many applications such as aerospace, automotive, consumer electronics, medical electronics, and defense.

In general, through hole resistors offer reliable performance and are cost-effective solutions in many applications. They are easy to install and can be used in high-performance applications where current needs to be accurately regulated. They also provide excellent cooling characteristics and are frequently used in high-power applications such as in motor controls and power supplies. The HHV1WSJR-73-120K Through Hole Resistors are particularly well-suited for applications such as power supplies, communications, computers and other electronic circuits.
