The capacitance and dissipation factors are constant with frequency, essentially noninductive, very low dielectric absorbtion.
The dielectric is specially prepared of purified high-molecular-weight polystyrene, having very high resistance and freedom from interfacial polarization.
Moisture sealing with Teflon® feed-through insulators assures high performance under adverse humidity conditions.
Maximum capacitance of 1.11µF in steps of 0.001µF.
