Fixed Inductors
Fixed inductors are passive components with electrical inductance, and are mainly used as transformers to suppress electric currents and decrease voltages. The ELJ-QF2N2DF is a two-element fixed inductor developed by Panasonic Electronic Components for use in automotive and energy-saving applications. This model is able to generate high-voltage and maintain stable operation even when subjected to a wide range of temperatures. This section will look at the application field and working principle of the ELJ-QF2N2DF.
Application Field
The ELJ-QF2N2DF is designed to be used in applications related to automotive and energy-saving components. It has a wide operating range from -55℃ to +150℃ and is rated for 100 to 1,200 VDC. This makes it suitable for automotive applications with a wide range of voltages and temperatures, including electric vehicles, hybrid electric vehicles, solar batteries, and power supplies.
Working Principle
The ELJ-QF2N2DF contains two separate coils that are connected in parallel, allowing for a high-voltage output. When a voltage is applied, an alternating current passes through the two coils at the same time, creating a magnetic field. As the current passes through the coils, the magnetic field induces a voltage in the other coil, producing a higher voltage output.
The two coils are made of ferrite material, which has a high magnetic permeability, allowing for higher inductance and better performance. The construction of the fixed inductor also includes a dielectric layer between the two coils to suppress capacitance and ensure stable operation. This prevents any unwanted current leakage between the coils, which could lead to erratic operation.
Conclusion
The ELJ-QF2N2DF is an advanced two-element fixed inductor designed for automotive and energy-saving applications. It has a wide operating temperature range and can generate a higher voltage output than standard fixed inductors. The two coils are made of ferrite material and separated with a dielectric layer to suppress capacitance and ensure stable operation even when subjected to a wide range of temperatures.
