The 1419A Decade Capacitors is a polystyrene decade capacitor. 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 1.11?F in steps of 0.001?F. Accuracy of ?1%.
