A planar transformer is essentially a transformer that uses flat windings, usually on a printed circuit board, instead of copper wire to form the coils. The PCB construction creates a different form factor that offers some unique advantages and a few tradeoffs.
A planar transformer uses flat windings that can be placed directly on a PCB. It is precisely the use of a PCB with tracks to the shape of the windings window that creates the planar form factor. The main advantages can be summarized as follows:
1. The hardness of the self-adhesive coil The hardness of the self-adhesive coil will affect its shock resistance and inductance. Generally speaking, few manufacturers will test the hardness of the self-adhesive coil.
Flat Hollow Inductor, a single-layer coil is wound around a paper tube or bakelite skeleton with insulated wires. Such as transistor radio medium wave antenna coil.
In the future, the development trend of "light, thin, short, and small" downstream electronic products will definitely determine the miniaturization and development of upstream electronic components.
