Fixed Inductors

Inductors, also known as coils, are passive two-terminal electrical components that store energy in a magnetic field created by the electric current passing through it. They consist of coils of insulated copper wire wrapped around a core of material such as ferrite or iron, which increases the inductance. Fixed inductors, as the name implies, have a fixed inductance value, meaning it cannot be changed or adjusted. One such example is the ER1641-392JM fixed inductor.

ER1641-392JM Application Field

The ER1641-392JM fixed inductor offers excellent and reliable performance in general electronic applications. It is designed specifically for automotive, professional audio/video, and other general electronic applications. It is a surface mount chip inductor with an inductance of 392nH, 26.85ohm DC resistance, and can handle up to 7A maximum current. It is constructed of a ferrite core with copper-clad aluminum(CCA) wire and has a high temperature flame retardant package, making it suitable for long-term use in a variety of environmental conditions. It is RoHS compliant and has a temperature range of -40 to +85 degrees Celsius.

ER1641-392JM Working Principle

Fixed inductors are designed to store magnetic energy and oppose changes in electric current. This is due to their high inductance, which is proportional to the number of turns of wire in the coil of the inductor. The more turns of wire, the higher the inductance. When a current passes through the inductor, a magnetic field is created around it. This magnetic field is then used to store energy. The stored energy causes a voltage drop across the inductor due to the opposing current, creating what is known as an inductive reactance. This reactance is proportional to the frequency of the current, and as the frequency increases the reactance also increases. The ER1641-392JM fixed inductor is designed to withstand these changes in voltage and frequency, allowing it to function reliably in a wide variety of applications.

Conclusion

The ER1641-392JM fixed inductor is a surface mount chip inductor with a high temperature flame retardant package, making it suitable for long-term use in a variety of automotive, professional audio/video, and general electronic applications. It offers excellent and reliable performance due to its high inductance, and its ability to resist changes in voltage and frequency. This makes it an ideal choice for a variety of tasks where stability and performance are required.
