If the contact resistance is low enough not to produce a noticeable
(dangerous) heat along itself, within reasonable limits, pin size alone
and its receptacle aren't enough to determine the effective current
capability.
When a connector doesn't introduce discontinuities along a transmission
line (a time domain terminology), its current capability decreases much
less rapidly with frequency than to what happens to larger contacts of
worse connectors that behave as less "transparent" to RF.
