SMD Inductors

SMD inductors are inductive components with a relatively simple construction. They consist of a wire that is spirally wound around a core made of a specific material or simply around air. These components are used in various circuits to protect them from sudden changes in current intensity.

SMD Inductors – Function

Despite their simple design, SMD inductors play a very important role. They filter voltage and protect against changes in current intensity. In many circuits, this is an essential component for proper operation. However, to choose the right SMD inductors for a particular installation, several important parameters of these components must be considered.

Key Parameters of SMD Inductors

There are various SMD inductors available on the market, suited for different circuits. If you are selecting these inductive components, you should pay attention to several important factors. The most crucial ones include:

• Inductance – This is the primary parameter of SMD inductors. Its value depends, among other things, on the number of turns and the size of the component. The unit expressing inductance is the henry (H). The higher the inductance, the more magnetic energy the component can store.
• Current – This factor specifies the maximum current that can be carried through the inductor. This parameter is expressed in amperes (A). It is crucial that its value is properly matched to the circuit's requirements.
• Resistance – This parameter defines the relationship between voltage and current in DC circuits. Its value is expressed in ohms (Ω).
• Tolerance – This value indicates the permissible deviation from the nominal inductance. It is expressed as a percentage.
• Operating Temperature – This range is influenced by various elements of the inductor's construction. It must be appropriately selected to suit the working conditions of the given circuit.

SMD Inductor Applications

Since SMD inductors provide circuit protection against changes in current intensity, they are used in many devices. They are primarily found in the input circuits of systems powered by the electrical grid. They are also used as ballasts in installations for powering fluorescent lamps. SMD inductors are also employed in various drive systems. It is evident that these inductive components can serve a variety of functions, making the correct selection of their parameters crucial. In our online store, you will find a wide selection of SMD inductors, allowing you to choose the right component for your specific circuit.
