(1) Switching frequency can be set externally (using a resistor and capacitor) from 100 to 600kHz.

(2) Without such a surface finish, the electronic components like transistors, resistors , capacitors and chips could not be fixed and electrically connected to the circuit.

(3) In those days computers consisted mainly of transistors, resistors , diodes, capacitors and miles of wiring.

(4) Usually this circuit consist of only resistors and capacitors.

(5) The component preforms may include resistors , capacitors, and inductors.
