Through-hole resistors, also known as leadsed resistors, are simple, inexpensive components that are used in many types of electronic circuitry. Their basic function is to provide resistance to electric current. They are typically used in the power supplies of electronic devices, digital logic circuits, and in power management systems.

There are three main types of through-hole resistors: axial, radial, and surface mounted. Axial through-hole resistors are the most common type, and they are often used in the production of power supplies, digital logic circuits, and in power management systems. They consist of a long cylindrical metal rod and two leads which extend from the top and bottom of the resistor.

Radial through-hole resistors consist of two metal plates with two additional leads that extend from the edges. These types of resistors typically have a higher resistance value, are more expensive, and are primarily used when there is not enough space for an axial resistor.

Surface-mount through-hole resistors are mounted directly onto the surface of the PCB, making them ideal for space-constrained applications. These types of resistors typically have a higher resistance value, are more expensive, and are primarily used when there is not enough space for an axial or radial resistor.

The B5J1R2E application field and working principle is a resistor designed for use in DC power entry panels. It contains two terminals with a maximum voltage rating of 300 volts. The terminals are threaded with a M3*0.5 standard thread to ensure secure connections. It is made of a fire retardant material and is rated for up to 20 watts of continuous power. The working principle of the resistor is based on Ohm\'s law, which states that the current through a resistor is inversely proportional to its resistance.

In summary, there are three main types of through-hole resistors: axial, radial, and surface mounted. The B5J1R2E application field and working principle is a resistor that is designed for use in DC power entry panels and is designed to provide resistance to electric current. It is typically used in the power supplies of electronic devices, digital logic circuits, and in power management systems.
