Through Hole Resistors are electronic components that, when connected to a circuit, can limit the flow of current to precisely the desired amount. Resistance is determined by the physical characteristics of the component and is usually measured in ohms. The PSM700JB-39R is a through-hole resistor with three key elements, a resistor element, a terminations, and a housing.

The resistor element of the PSM700JB-39R is a spiral wound resistor. The resistance of the resistor element is dependent upon the material properties and construction of the resistor element. It is made of an alloy film on a mica or ceramic substrate which is advanced by winding metal foil on the substrate. The winding is then fired at high temperature to stabilize the resistive material, thus forming a stable resistor element. This type of resistor allows for consistent and reproducible tolerance levels.

The terminations on the PSM700JB-39R are the ends of the resistive element that are connected to the circuit. These terminations usually incorporate a metal-glass seal that provides insulation between the resistor element and its environment as well as increased mechanical reliability. The terminations are available in variety of forms including SMD, leads to wires, and rivets.

The housing on the PSM700JB-39R is an insulator material that encloses the resistor element. The housing serves to protect the resistor element from high temperatures, shocks, or other harsh environmental conditions that could lead to premature failure. It also prevents short circuits by maintaining a safe distance between the resistor element and surrounding conductive elements.

The PSM700JB-39R can be used in a variety of applications and fields. It is an ideal choice for applications that require high power rating and high voltage rating, such as automotive and industrial applications. It is also a popular choice for applications that require precision resistor values, as the PSM700JB-39R provides consistent and reproducible tolerance levels. Additionally, its small size and low profile make it suitable for applications with limited space.

The PSM700JB-39R works in accordance with Ohm\'s law. Its resistance is proportional to the amount of voltage that is applied to it. When a voltage is applied, current flows through the resistor and is equal to the ratio of the voltage divided by the resistance. The current is then dissipated as heat, depending on the power rating of the resistor. When the voltage increases, the current also increases, thus dissipating more heat and limiting its current carrying capacity.

Overall, the PSM700JB-39R is an excellent choice for applications that require high power rating, high voltage rating, and consistent and reproducible tolerance levels. Its small size and low profile make it suitable for applications with limited space, and its ability to dissipate heat in accordance with Ohm\'s Law makes it reliable in any electrical circuit. Through Hole Resistors like the PSM700JB-39R are essential components of modern electronics and provide precise control over the amount of current that flows through an electrical circuit.
