Poznámky redaktora
The parts are immersed aqueous passivation emulsion.1 Silver The conductivity silver excellent, better than gold fact.069 14.3 .21: 176 ____________________________________________________________ Material Specific resistance Conductivity in Ohm mm2 m in Ohm mm2 Aluminium 0.7.023 43. This surface protection used for aggressive environments. 4.061 16. Due the thinness the layer, the poor electrical conductivity nickel is insignificant.12 8. The brass contacts are first plated with 3-pm nickel layer (diffusion barrier) then with 2-pm gold layer the contact area.4 The Specific Resistance and Conductivity Various Materials Table 4. This surface protection sufficient for almost all industrial connectors applications. The contacts are silver-plated, with layer thickness pm. The electrical conductivity gold significantly less than that silver, but due its constant contact resistance, used special applications.5 Tin 0.7. brownish sulphide layer easily develops its surface.016 61 Zinc 0.7. Silver produces moderate diffusion barrier. 4.4.3 Nickel A 5-pm layer nickel applied protect large-surface parts, such earth panels.2 Gold The finest surfaces are created with gold plating. 4.5 Copper 0.7.028 36 Gold 0.5 Silver 0.017 58 Brass (CuZn40) 0.067 15 Nickel 0. This can be very important, especially for small currents and low voltages
