Abstract

A fail-safe lead configuration for surface mountable chip-like polar electrical components wherein the lead of a first polarity is singulated and the lead of the second polarity is bifurcated, having the branches spaced a part such that a rotation of the device in its intended mounting location, thus reversing its polarity, or a displacement from its intended, position will result in an open circuit rather than a short circuit or other circuit failure.
