Foil resistors may have an advantage in its robustness in number of applications. VPG Foils Resistors demonstrated some of its capabilities in set of videos benchmark its features with thin and thick film technologies:
Benchmark of foil, thin, and thick film resistor technologies in overload pulse. Due to the homogeneous nature of the foil resistor, it is the only of the three to experience no change from the high power pulse.
Thin vs Thick vs Foil Resistors Construction and Pulse Load Test
PC board flex, caused by shock, vibration or thermal expansion can cause SMD resistors to change value due to the “strain-gage effect”. This demo shows comparison of thin vs thick vs foil chip resistor technology under such load and in particular the “flex termination” resistor family robustness and superior design to remain stable in rough applications.
Thin vs Thick vs Foil Resistors Flex and Strain Test
This demonstration compares the TCR and PCR stability of chip foil resistors to inexpensive commercial grade thick film resistors.
