Circuit Diagram
AK0405 1/4 Wraparound's design allows for face (film side) down mounting which preserves continuity between the resistor element and circuit traces thus minimizing mismatches. Additionally the 1/4 Wraparound terminal provides a 'solder fillet' to aide in visual inspection on the solder joint.
