Nearshore / Offshore Electronics Manufacturing

Comtronic is a low-cost electronic magnetic components and assembly manufacturer located in its own Duty Free-Zone in Tegucigalpa, Honduras 

Operations commenced in 1990 by two British expatriates and additional Honduran shareholders as a Honduran Public Company with a vision to manufacture electronics for export taking advantage of parts requiring a high labor content in combination with low Honduran labor rates. 

After a successful start-up, Comtronic signed up in 1993 with Coiltronics, a Florida based company specializing in Magnetics, for the exclusive manufacture of their standard and custom products.

Today, the 136 strong Comtronic team are highly skilled and certified in the manufacture of magnetic components for several US based companies including the manufacture of transformers, inductors, chokes, and custom magnetics, many of which are used in the aviation and medical industries requiring zero defects and full traceability.  We also manufacture stators for electric motors and through-the-board components on PCB’s. 


In 1997 Comtronic moved into its own Duty Free Zone Factory of 45,000 square feet just 10 minutes from the Tegucigalpa International Airport, which is just a two-hour direct air flight from Miami or Houston on the U.S. Central Time Zone.

Comtronic is committed to develop an organizational culture that allows for continuous product improvement and full customer satisfaction. We are ITAR and ISO-9001:2015 Certified,  J-STD-001 Soldering Certified and work closely to  FOD and 5S Standards. We are working to get AS9100 Certification Soon.
