Through Hole Resistors

The PSP500JB-7R5 is a type of through hole resistor that is commonly used in low-level electronic circuits. This resistor is a through-hole device that is relatively simple to install and use. Its circuit size is quite compact, which makes it a practical choice for many applications.

Application Fields

The PSP500JB-7R5 is primarily used in low-level electronic circuits such as audio amplifiers, digital-to-analog converters, and baseband processors. However, it can also be used in low-voltage, high-frequency circuits, such as digital receivers and base station field switches. Additionally, this resistor is also suitable for applications where high currents are expected, such as in switch-mode power supplies.

Working Principle

This resistor performs through-hole resistance by using its resistance element, an encapsulated material in its interior. The resistance element is a type of foam material which contains metal particles, such as silver or copper, embedded in it. This metal has a high electrical resistance since the metal particles are not in direct contact with each other. Instead, current flows in and around the particles, which results in a high electrical resistance.

The internal resistance element is also enclosed in a metal-oxide film. This film is formed by the reaction of the section\'s environment with the metal particles inside the foam material. The resistance element is also connected to the sections of a terminal inside its body. When voltage is applied to the terminals, current is sent through the element to and from the two terminals, and it is the resistance element that is providing resistance.

The PSP500JB-7R5 features high-temperature operation capabilities. It can be used in environments with temperatures ranging between -40°C to 85°C. This makes it a suitable device for high-temperature electronics applications such as in automotive applications.

The PSP500JB-7R5 is a reliable device that is cost-effective and easy to install. It is also a practical choice for many applications that require high resistance. Its operating principles and application fields make it a versatile resistor with a variety of uses.
