Through Hole Resistors

Through-hole resistors are electronic components typically used to limit current in circuits. They are cylindrical in shape and constructed out of resistive material, most often carbon composition or coiled wire. Externally these components are marked with a sequential number system which denotes their electrical characteristics. The ALSR05450R0JE12 is an example of an axial lead mounted Through Hole Resistor.

Application Field

The ALSR05450R0JE12 resistor is most often used in radio frequency applications that require very low inductance. The axial lead construction allows the resistor to be mounted in close proximity to the drive unit without the fear of significant inductance buildup. Additionally, the axial lead construction of this resistor simplifies the mating of components and circuit boards by directly mounting the resistor in place.

The ALSR05450R0JE12 resistor is constructed of a ceramic rod encased in a metal housing with the connection terminals being a pair of axial leads on either end of the rod. This configuration provides a reliable path from the PC board to the resistor element, which is essential for devices that operate in extreme temperature or vibration environments.

Working Principle

The ALSR05450R0JE12 resistor operates according to Ohm\'s law where the resistance is proportional to the wire material used. As a result, current is limited when passing through the resistor according to the level of resistance provided. This specific design of resistor limits the amount of energy that is dissipated by the resistor, resulting in lower thermal dissipation and longer service life.

The ALSR05450R0JE12 resistor also features a low self-inductance rating. This helps reduce inductance effects when the resistor is used in extremely high frequency applications. Lower inductance prevents the buildup of impedance which can cause oscillations and interference in the circuit.

Conclusion

The ALSR05450R0JE12 is a Through Hole Resistor that is perfectly suited for radio frequency applications that require very low inductance. It is designed to provide a reliable connection from the PC board to the resistor, and offers superior thermal dissipation and low self-inductance ratings. All of these factors make the ALSR05450R0JE12 an ideal solution for radio frequency applications.
