Operating Envelope

Figure 5 shows the voltage and current operating envelopes
for the T7446L and T7446H. The T7446L relays are initially
gold clad and have an initial resistance of 50 mOhm
maximum. However, operation at high voltages and currents
will remove the gold and the closed resistance will increase
substantially. This increased resistance reduces its ability to
subsequently switch very low power loads.
