PC Mount, Low-Profile Transformers Banner

We offer PC-mount transformers in a number of configurations to meet both the power and dimension requirements of your electronics projects. In addition to the iron-core, through-hole transformers described on this page, we also manufacture surface-mount transformers in an array of configurations.

LPC-STYLE TRANSFORMERS

LPC-Style Transformer

Low-profile PCB-mount transformers (LPCs) are designed to take up minimal vertical space. These types of transformers can be used for nearly any printed circuit board configuration where a slim overhead design is required. The semi-toroidal construction helps reduce hum as well as radiated magnetic fields.

PRODUCT CHARACTERISTICS

  • Low Profile: Only .65 inches tall.
  • Dual Primaries: 115/230 V, 50/60 Hz
  • Semi-toroidal Construction: Hum-Bucking construction, reduces radiated magnetic fields.
  • Non-concentric windings: Reduces inter-winding capacitance and eliminates the need for electroctatic shield.
  • 1500 Volts RMS HIPOT: Primary and secondary coils wound on separate sections.
  • Wide selection of outputs available: Selection ranges from 5 to 230 volts standard.

Custom Configurations Available – Contact Sun Transformer for details.

Enclosed Windings, PC-Mount Transformer

These PC-mount transformers meet international isolation standards. They utilize an E-I laminate core and offer an effective alternative to LPC-style transformers when greater output power is needed and vertical space is not quite as limiting.

Sun Transformer can design and manufacture PC-mount transformers to meet nearly any requirement. For more information about how we can provide your transformer needs, please send us your specifications or call us today!
