PF2205-1R8F1

This article introduces the application field and working principle of a specific type of through hole resistors--PF2205-1R8F1. This resistor type is a fixed resistor with an establishment of jumper wire terminals on the resistor board or PCB, in order to let the current flow through the resistor.

PF2205-1R8F1 is typically used for signal conditioning and have a low impedance that help limit current flow. The small size component would often be used in grid line design of the PCB, especially when space is a major concern. Typically the resistor has a high voltage rating of up to 200V and can handle high temperatures. It can also be used in high-frequency circuits as it can handle the high-frequency noise stabilization.

PF2205-1R8F1 through hole resistors usually come in axial leaded package with two lead wires and a body, which is what gives the device its \'through hole\' characteristic. The lead wires are inserted into the hole on the PCB and soldered into place for permanent connection. On the exterior, a grey or black coloured material insulates the individual component.

Going deeper into the working principle of PF2205-1R8F1, electrical current goes through the resistor by means of the two external contacts. The terminal extends out from the body, providing the electrically conducting path needed for current flow. The material composing the resistor determine the resistance of the resistor. In PF2205-1R8F1, it is constructed with a resistance element, usually carbon, that is very stable with temperature and environment changes.

In addition, the current flow also depends on the length, diameter and surface area of the resistor. The longer and thinner the resistor is, the less resistance and, hence, more current flows through it. As for the surface area, the larger the surface area, the higher the contact resistance of the resistor.

Furthermore, the applied power of the resistor can be determined by multiplying the voltage passing through the resistor by the current. The power level of PF2205-1R8F1 resistor that it can handle depends on the wattage rating printed on the body of the resistor. This indicated the maximum operating temperature the resistor can handle before burning out.

In summary, PF2205-1R8F1 through hole resistors are very versatile components with many application fields. The resistor has a wide range of resistance and power ratings, and the body is small enough to fit in most designs. They are used for signal conditioning, and they can handle high voltages and frequencies, making them great choices for many applications.
