Core Functional Technology of Fixed Inductors

1. Inductance: The primary function of a fixed inductor is to store energy in a magnetic field when electrical current flows through it. The inductance value, measured in henries (H), determines the amount of energy that can be stored and influences the inductor's behavior in circuits.

2. DC Resistance (DCR): This is the resistance encountered by direct current flowing through the inductor. A lower DCR is desirable as it reduces power loss and improves efficiency, particularly in high-current applications.

3. Saturation Current: This is the maximum current the inductor can handle before the core material reaches saturation, which results in a significant drop in inductance. Knowing the saturation current is essential for ensuring reliable operation in applications with high current demands.

4. Self-Resonant Frequency (SRF): The frequency at which the inductor resonates with its parasitic capacitance. Above this frequency, the inductor behaves more like a capacitor, which can affect circuit performance. Understanding SRF is crucial for applications involving high-frequency signals.

5. Temperature Coefficient: The performance of inductors can vary with temperature changes. The temperature coefficient indicates how inductance changes with temperature, which is important for applications exposed to varying thermal conditions.

Applications of Fixed Inductors

1. Power Supply Circuits: Fixed inductors are integral in DC-DC converters and power supply circuits, where they filter and smooth voltage levels, ensuring stable power delivery to electronic components.
