Custom Wound Components

Spring have been manufacturing audio, power and ferrite transformers for over forty years. Whether you require a small batch of a custom design or medium to large volume production of a custom transformer, we can help. The transformer and coil types we manufacture include: metal detection search coils, ETD (and similar) ferrites, small mu-metal audio transformers, M6 grain oriented matching transformers and RM style ferrite transformers as well as many others. We also supply a number of toroidal core inductors for power and audio applications. We have Far East partners to assist in extremely high volume orders of transformers, coils and toroids.
