The Latent Effect of ESD on Thin Film vs Bulk Metal® Foil Resistors
Many engineers uare not aware of ESD’s detrimental effects to thin film resistors. They havethe erroneous belief that damaged resistors can easily be culled from the lot, or detected and removed after being installed in equipment. However, in some resistors ESD produces latent or hidden damage that doesn't show up until the units cause catastrophic system failure in the field. This demonstration shows that the ESD damage to thin film resistors is usually undetectable or latent, while Bulk Metal® Foil resistors are unaffected by the same levels of ESD.
