Contact plating (finish) provides corrosion protection for base metals and optimizes the mechanical and electrical properties of the contact interfaces.

In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit.

Frequency Response describes the range of frequencies or musical tones a component can reproduce. Frequency response measures if and how well a particular audio component reproduces all of these audible frequencies and if it makes any changes to the signal on the way through.
