ALSR05400R0JE12

Through Hole Resistors (THRs) alludes to the generic term for electrical components that have a resistive element that resists the flow of the electrical current. The ALSR05400R0JE12 is a type of THR, which acts as a voltage divider providing a precise amount of resistance in circuit designs. It is relatively common and serves as one of the most used components in electrical engineering.

ALSR05400R0JE12 Application Field

The ALSR05400R0JE12 is mainly used in microwave telecom and radio applications, where its small size and high impedance characteristics are ideal for these applications. This THR can also be used in printed circuit boards (PCBs) and on flexible circuit boards (FCBs). In addition, the THR is used in power amplifiers, linear and non-linear circuit designs, and other general electronic applications. The THR is also frequently used in the antenna systems of automotive electronics, military systems, and medical equipment.

ALSR05400R0JE12 Working Principle

The ALSR05400R0JE12 is typically made up of a ceramic body with an internal resistor layer. This internal resistor layer is made up of metallic conductive elements that are arranged in a specific manner, forming a closed loop. When an AC signal is applied to the THR, the resulting current is split by the resistor layer into two different voltages. These two voltages, which are known as the common-mode voltage and the differential-mode voltage, can be set to precise levels depending on the size and shape of the resistor in the THR.

The common-mode voltage is the signal voltage of the THR, and it is applied all across its components. In contrast, the differential-mode voltage is the differential voltage that is obtained when the common-mode voltage is subtracted from one of the other two voltages. This differential voltage, in turn, helps to regulate the current flow in the circuit.

The arrangement of the resistor layer in an ALSR05400R0JE12, which is pre-determined by the manufacturer, determines the impedance that the THR will have. As such, if an engineer needs a specific type of THRS, such as one with a higher or lower impedance, then they will need to select the intended THR based on their desired impedance.

The operation of the ALSR05400R0JE12 is similar to that of a potentiometer, where the resistance can be adjusted to vary the amount of current that passes through the resistor layer. However, unlike a potentiometer, the ALSR05400R0JE12 has a fixed amount of resistance. As such, it can not be adjusted and must be replaced if the intended current level needs to be adjusted.

Conclusion

In conclusion, the ALSR05400R0JE12 is a type of THR that is used in various electronic applications, such as microwave telecom and radio applications. Its small size and high impedance characteristics make it suitable for these applications. Additionally, its working principle, which is based on a resistor layer that splits the applied AC signal into two voltages, allows it to regulate the current flow in a circuit. As such, if an engineer needs a specific type of THR, then they should select the desired ALSR05400R0JE12 based on their intended impedance.
