TRACK PARAMETER CALCULATOR

This calculator uses rule of thumb data which will be more than accurate enough in most cases. It should however, be used with intelligence.

Parameters marked with a * are required. Others are optional.

 

Track width	thou mm	*Enter the track width in your preferred units
Copper thickness	0.250.50.7511.523---- oz/sq. ft thou µm	*Enter the copper thickness in your preferred units
Track length	inch mm	Used to calculate resistance, voltage drop and power
Operating current	A	DC or RMS operating current - used to calculate voltage drop and temperature rise (<30A)
Internal track?		Select if the track is on an internal layer - used to calculate temperature rise
Frequency	MHz	Signal frequency - leave at 0 for DC>
Reference plane?		Select if there is a plane under the track - used to calculate skin depth proximity effect

 

Cross sectional area	sq. thou sq. mm	Cross sectional area of the track
Temperature rise	°C	Calculated at selected frequency - make sure that you have selected internal or external track above
Skin depth	thou µm	Skin depth at selected frequency
Skin ratio	%	Percentage of cross sectional area used at selected frequency
Resistance	ohms	Resistance of track at selected frequency
Voltage drop	mV	Voltage drop along track at selected frequency
Power dissipated	W	Power dissipated in track at selected frequency
