Key Internal Technologies The "RG" series is known for its **Metal Glaze Thin Film** construction, which offers several advantages over standard thick-film resistors: ### Thin Film Sputtering Unlike thick film resistors that use a paste, these are created using a sputtering process. This results in a very uniform resistive layer, allowing for the extremely tight **±0.05% tolerance**. ### Inorganic Passivation The resistor element is covered by an inorganic glass passivation layer. This provides: * **Superior Reliability:** Resistance to moisture and harsh environments. * **Low Noise:** Extremely low current noise compared to thick film. * **Long-term Stability:** Minimal "drift" in resistance value over thousands of hours of operation. --- ## 3.
