The capacitor can have values between 0.01 and 10 ?F, depending on the application. As in the previous article MEC169E, the load can be replaced with an 1 kΩ resistor. With R = 10 kΩ and C = 0.047 ?F, the circuit can be used as a contact conditioner driving TTL and CMOS circuits. See other articles in this section to determine which blocks can be added to this circuit to control high-current loads.
