To date, Signal Transformer has released a family of useful design kits to support engineering’s design and prototyping efforts for power line, EMI, and PFC frequency applications. There is a high current toroidal inductor kit, a high current toroidal common mode choke kit, and a multi-purpose kit of surface mount inductors along with a select number of through hole high current toroidal inductors. Signal continues to expand its portfolio of kits further.
