ELC-09D121DF Fixed Inductors

Fixed inductors are electrical components that store energy in a magnetic field when an electric current flows through them. Generally, these components are made with a core material such as ferrite, which is wrapped with fine insulated copper wire and then encapsulated in a ceramic or plastic shell. The ELC-09D121DF fixed inductor is an enclosed-style model that is concentric, meaning that the core is housed inside a hollow tube.

Applications

Fixed inductors are commonly used in many types of electronics. They can be found in broadcast and professional audio systems, medical equipment, consumer electronics such as televisions, radios, and gaming systems, and in automotive applications such as run capacitor banks and electric fuel pumps. The ELC-09D121DF is designed for use in switching power supplies, low-noise applications, DC-DC converters, and telecommunications.

Product Details

The ELC-09D121DF has a suitable inductance value of 1.2mH ± 10 percent, a maximum DC resistance of 0.07 ohms, and is rated for currents up to 3 amps. Its construction material is iron powder, which is considered superior to ferrite as it can handle higher current and frequency without additional heating. The inductor also features an operational temperature range from -40 to + 115 degrees Celsius and a relatively low rate of self-resonance at 15MHz.

Working Principle

The ELC-09D121DF fixed inductor works by converting electrical energy into magnetic energy when an electric current passes through it. When this happens, the coil, which is wound with insulated copper wire around the core, creates an electromagnetic field. This field then generates a voltage potential, which is proportional to the amount of current flowing through it and the inductance of the coil. This voltage potential is then used to power other electrical components.

Conclusion

The ELC-09D121DF fixed inductor is a popular choice for use in a variety of consumer electronics, medical devices, automotive applications, and other industrial uses. It is a concentric-style model that features an iron powder core, a suitable inductance value of 1.2mH ± 10 percent, and a maximum DC resistance of 0.07 ohms. Furthermore, it can operate in a wide temperature range and has a low rate of self-resonance at 15MHz. Finally, it functions by converting electrical energy into magnetic energy via the electromagnetic field generated between the coil and core.
