Path resistance is a combination of relay contact resistance and trace resistance. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance rises rapidly above 1.0 Ω.
Characteristic impedance (Z0) |
75 Ω nominal |
Values in parentheses are typical.
