Power Inductors - Leaded
Leaded power inductors are electronic components used in electrical circuits to store and release energy in the form of magnetic fields. They are called "leaded" because they have leads or terminals that allow for easy connection to a circuit board or other electronic components.
Power inductors are designed to handle high currents and provide inductance values suitable for power applications. They are commonly used in various electronic devices, including power supplies, voltage regulators, motor control circuits, and filters.
The core of a power inductor is typically made of a magnetic material such as ferrite or powdered iron, which helps enhance its inductance and efficiency. The core is usually enclosed in a protective housing, which can be made of materials like plastic or ceramic.
Leaded power inductors come in various shapes and sizes, ranging from small through-hole components to larger packages. The leads or terminals allow for easy soldering or mounting onto a circuit board, providing a secure electrical connection.
Power inductors are characterized by their inductance value, rated current, and DC resistance. Inductance is a measure of the inductor's ability to store energy in its magnetic field and is typically specified in henries (H), millihenries (mH), or microhenries (µH). The rated current indicates the maximum current that the inductor can handle without significant performance degradation or overheating. The DC resistance refers to the resistance of the inductor's winding and influences its power loss and efficiency.
Leaded power inductors are selected based on the specific requirements of the circuit, such as the desired inductance value, current handling capacity, physical size, and operating frequency. They are typically chosen to provide efficient power conversion, noise filtering, and energy storage in various electronic systems.
In summary, leaded power inductors are electronic components used to store and release energy in the form of magnetic fields. They are designed for power applications, offer a range of inductance values and current handling capacities, and can be easily connected to circuits through leads or terminals.
