Through Hole Resistors are used to produce precise electrical resistances. Among them, PSP400KB-1K1 is a superior through hole resistor in terms of stability and accuracy. This article will discuss the application field and working principle of this resistor.

Application Field

The PSP400KB-1K1 through hole resistor is ideal for applications that require precision electrical circuitry and stable currents. This resistor type is widely used in medical engineering, automotive systems, integrated circuits and consumer electronics products. Its highly reliable characteristics make it an excellent choice for those applications that require stable electrical resistance values over extended time periods. In addition, excellent thermal characteristics mean that this resistor can be used in power system control circuits or load circuits, where currents can be subject to fluctuations.

Working Principle

The PSP400KB-1K1 is a non-polarized through-hole resistor type that is designed with resistor elements that are connected in series, parallel or mixed arrangements. It has a tolerance range of 5%. The resistor element is comprised of a combination of manganese- and nickel-doped ceramic beads, forming a “U-shape”. The ceramic beads are covered with an insulating material that prevents the passage of electric current through the resistor, thus providing precise resistance values. Furthermore, the ceramic beads are not affected by temperature or aging, so the resistivity remains stable and accurate for an extended period of time.

In conclusion, the PSP400KB-1K1 through hole resistor is an excellent choice for applications that require accurate and stable resistances. It is widely used in medical engineering, automotive systems, integrated circuits and consumer electronics products due to its reliable characteristics and the accuracy of its resistance values. In addition, it offers excellent thermal characteristics that enable stable currents over an extended period of time.
