Why Do I Need an Inductor?
Generally, most electronics need inductors (also called chokes). Similar to a transformer, an inductor creates and stores a magnetic field as current passes through the wire. Unlike a transformer, which can have multiple primary and secondary windings, an inductor typically only has one winding. A common mode choke is a special type of inductor that consists of two windings in opposite directions. Inductors can be used to:
- Store and transfer energy
- Filter harmonics from line frequencies
Applications include:
- Energy storage
- Solar/wind energy inverters
- Inductive filter circuits (in collaboration with capacitors)
- Signal processing
- Switching power supplies
Advantages of a Toroidal Inductor
- Quicker cooling than a traditional laminated inductor
- Lower electromagnetic interference (EMI)
- Near complete magnetic field cancellation (lower stray losses)
- Lower winding resistance, Ω (shorter length per turn)
- Compact size (less volume and weight)
Our team of engineers can design a custom 50/60 Hz toroidal inductor to meet your inductance, current, size and mounting requirements.
