What is long electrode resistance? What are the characteristics Long electrode patch resistor is a special structure of patch resistor. By using side electrodes as solder pads, the contact area between the solder pads and the PCB is increased, resulting in better heat dissipation and high current. It has excellent stability and impact resistance during use. Long electrode surface mount resistors are divided into metal foil long electrode surface mount resistors, also known as alloy resistors, and wide electrode surface mount resistors in later processes. Their main advantage is their strong impact resistance.
