GB International designs and manufactures surface mount components for a variety of power supply and conversion applications.
A surface mount transformer or inductor is a device that is designed either on a toroidal or bobbin core. For the toroidal core, the wound coil is attached to a surface mount header. A surface mount bobbin is used for the the bobbin type core structure. Surface mount components offer small size, and if designed on a toroidal core less leakage inductance and lower electromagnetic interference (EMI).
Where are surface mount transformers and inductors found?
  1. Switch mode power supplies.
  2. Filter applications.
  3. Electromagnetic Interference (EMI) sensitive circuits.            
  4. Any circuit board utilizing surface mount technology.
Design upper limits of a surface mount transformers and inductors:    
  • Typical minimum requirements to be specified for a surface mount component are:        
        • No load inductance in uH.
        • Full load inductance in uH.
        • DC Current in Amperes.
        • AC Current in Amperes peak to peak.
        • Operating frequency is needed for core calculations and wire sizing.
  • Core material is selected for the known operating frequency or frequencies.
  • Other surface mount inductor design considerations are space limitations of the bobbin or toroid mounting technique.
  • Size limitations are limited by available surface mount bobbins and headers.
Surface mount transformer and inductor designs vary widely in terms of power rating, inductance, voltage level, operating frequency, size, impedance, bandwidth (frequency response), packaging, winding capacitance, and other parameters.
