The maximum continuous current rating for an electronic cable is limited by center conductor size, number of conductors contained within the cable, maximum temperature rating of the cable, cable length, and environmental conditions such as ambient temperature and air flow.

The guide is to be used as a reference only and Angstrom Sciences, Inc. accepts no liability for above power recommendations.. Other process variables, such as cable length, operating temperature, and duty cycle, can greatly effect ratings. Please consult Angstrom Sciences, Inc. for further recommendations.
