ABSTRACT:
To protect a load circuit on a printed circuit board, a pair of input circuit conductors are placed close together to form a spark gap. A load limiting resistor is placed in one of the conductors. A tape with adhesive around its perimeter is secured to the circuit board over the spark gap to trap air or other gas at the spark gap. A conformal coating covers the circuit board including the tape and the resistor.
