Intercept Impedance Calculator app for iPhone and iPad

Intercept Technology’s Impedance Calculator allows engineers specializing in the design and layout of printed circuit boards to calculate the total electrical impedance for the following transmission line types:
Microstrip
Embedded microstrip
Edge-coupled microstrip
Symmetric stripline
Asymmetric stripline
Broadside-coupled stripline

Enter physical line values for dielectric height/thickness, wire width, wire thickness, relative dielectric constant and wire gap (if applicable) to calculate impedance. The calculator also determines wire width if the impedance is known.

Additional information:
Units may be selected as microns or MM as needed. Impedance is calculated in Ohms.
