Custom SMT/SMD Transformers & Inductors

Surface Mount Technology magnetics refers to a method of attaching transformers and inductors to a printed circuit board. SMT parts are generally soldered directly to the PCB, eliminating the hassle of wiring and mounting. For this reason, SMT components are ideal for electronics produced in high volume.

Any standard through-hole component can be produced as a more compact SMT component that will occupy minimal circuit board area. This is typically accomplished using bobbins with SMT pins rather than hole pins. Otherwise an SMT design is identical to its through-hole counterpart.
