Toroidal Transformers

The advantage of the symmetrical toroidal shape is the minimal amount of magnetic flux that escapes outside the core (leakage flux). Toroids radiate less electromagnetic interference (EMI) to nearby circuits or equipment. Toroid transformers can be quieter, and produce less audible hum than other transformers. Toroids provide slim profiles for height-restricted mounting requirements and are available in a variety of sizes and materials. In certain applications, Glen Magnetics engineers can design an equally effective but less expensive non-toroidal transformer for customers.
