Thin-film technology involves sputtering or vacuum-depositing extremely thin layers of conductive, resistive, or dielectric materials onto a ceramic or glass base. This process creates components with tight tolerances, low noise, and excellent high-frequency performance. It is widely used to manufacture precision resistors, capacitors, and specialized semiconductor substrates.
We need to specify thin-film resistors for the feedback loop to keep the thermal drift under control.
Thin-film resistors are generally more precise and have better temperature coefficients than thick-film types, but they cost more and handle less surge power.
