The color of the base indicates the maximum capacitance (see Electrical Data Table). The dielectric is a film of polypropylene (PP), polycarbonate (PC) or polytetrafluorethylene (PTFE), which supports the vanes in such a way that good stability is ensured and no microphony can occur. Flux absorption between the vanes is prevented. Cleaning with solvents is not advised. Versions are available with either a spindle, or a horizontal spindle. Both versions have top adjustment by means of a screwdriver or trimming key and bottom adjustment by means of a key. QUALITY LEVEL: Sampling and data evaluation for quality level in accordance with MIL-STD-D and IEC 64 : <. % major defects <.6 % minor defects Each capacitor is tested for minimum C max and is also subjected to the full test voltage.
