Coil formers are components found in a transformer(an electrical device that transfers energy between two or more circuits). They're commonly used in electrical printed circuit boards(PCBs) to produce the energy needed to power electrical machines such as motors and generators.
Coil former applications
Coil formers are commonly used in transformers or as reactors in switch-mode power supplies. Transformers are used to bring voltage up or down in an AC electrical circuit. Both transformers and switch-mode power supplies can be used to convert mains AC power to DC power.
There are transformers all over every house. They are inside the chargers used to charge your mobile phone and other personal computing devices. They're also found in loudspeakers and microphones.
Advantages of using coil formers
Coil formers come in different types depending on whether you need to mount them horizontally or vertically.
Coil formers are usually made with an insulating material, such as thermosetting plastic, and are resistant to soldering and soldering heat.
