Resistors

TFS can make resistors from 0.1 Ohm to 1GOhm. Resistors are typically printed at 80% of final design value and then laser trimmed to the final value.,  Typically thick film resistors are designed with 2%-5% general tolerance.   1% resistors are possible with an approriate design,  Essentially the larger the resistor, the easier that it is to trim accurately.  Very small resistors make it difficult to trim parts precisely. 

Resistors usually have a protective coating of low temperatue glass.
