The RGLL/RGVP, being constructed of continuous metal, claim better noise characteristics than thick film resistors. The RGVP’s data is shown in the chart on this slide. Thin film is deposited in an atomic/molecular process allowing the natural grain/crystal structure to be preserved as deposited. As thick film resistors show -15dB at their best, the RG series’ noise level is -25 dB to -40 dB.
