Induction chokes are otherwise called coils. They are passive elements, whose task is to filter current. This is necessary, among other things, when powering a microprocessor located in the board. A choke consists of a wire that is spirally wound onto a core. However, there are coils without a core and the wire is filled with air. The most important parameter to pay attention to is inductance. This determines how to counteract changes in the current flowing through the winding. Inductance is determined by the wire cross-section and its length. Other parameters that determine the effectiveness and purpose of the choke are maximum current and resistance. Chokes are available in Botland store in different variants. You can opt for chokes made by the method of the chronic, that is THT, as well as the surface, feel the SMD. In addition, in the case of THT chokes, there are also options for vertical and axial chokes, while for SMD we have wire chokes available. Induction chokes throttle current or act as a radio wave receiver in the LC system.

Performance of an induction choke
Induction chokes as filter elements. They are placed in a circuit similar to a resistor, i.e. in series. They are perfect for removing variable interference from the current, while leaving the signal of constant voltage intact. The operation of the choke can be compared to that of a capacitor. If we cut off the power supply, it will still be intact for some time. In case of a capacitor, however, there is a reserve of current after the power supply has been disconnected, which has been stored by it. As far as the coil is concerned, under the same circumstances it will still produce current for a while.
An inductive choke is otherwise called a coil. But are these terms interchangeable and mean the same thing? We can talk about a coil in the context of an inductive component. The choke should be called a filter element. Coils differ in their inductance. They are expressed in henry, which is indicated by the symbol H. They also have different resistance. The inductors are mounted in series while the capacitors are mounted in parallel. When it comes to direct current, a coil is not a major obstacle. It is definitely different with alternating current, where it is very effective.
Use of induction chokes
Induction chokes can be used widely in the field of electronics and the electrotechnical industry. They are used in drive systems and power electronic devices, where they effectively minimize the amount of electromagnetic interference that occurs during operation. Their presence in alternating current circuits is aimed at limiting short-circuit currents. Chokes should also be used in AC circuits. They are also designed for pulse stabilizers operating at high frequencies. Chokes are also used if we want to break the transistor control current in thyristor-based converters.
Types of chokes in our offer
The coils differ in design, purpose, inductivity and performance under specific conditions. Our offer includes axial chokes, which consist of feet on two opposite ends of the component. An alternative are vertical chokes, in which the legs are led from one end. We also have wire chokes and SMD wire chokes. They have inductance from 4.7 μH to 1 mH, and the permissible current is 0.4 mA - 5A.
Feel free to browse our offer of induction chokes filtrating current and distinguished by their versatile application. We also offer professional assistance in choosing the best choke to fit the electronic system, its specificity and technical parameters. Chokes are sold as single pieces or in sets with a set of coils of a specific type. Check what we have prepared for you!
