Other Available Configurations
RK Series 1/4 Wraparound chip resistors are optimal for RF & Microwave applications. Their 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.

Face down mounting preserves circuit continuity for excellent performance over frequency.
Solder filet allows for proper inspection of
