LOW PROFILE PC MOUNT TRANSFORMERS
Our 70000-series PC Mount toroidal step-down transformers offer the same features as our non-encapsulated toroidal power transformers,
namely, very low EMR (magnetic stray fields), quiet operation, low temperature rise, low profile, low no-load current and very low no-load
losses.
The cores are produced from a continuous strip of high grade silicon steel, and the windings are placed concentrically around the core.
This is the ideal magnetic path, lacking air gaps or discontinuities thereby optimizing the use of magnetic flux for power transformation and
significantly reducing idling currents when the load is removed.
Additionally, the transformers are designed for PCB mounting and can be secured prior to the soldering process through the use of a
central screw receptacle that will accommodate either M4/M5 metric machine screws, or self-tapping types.
