The 39D series Powerlytic® Electrolytic Aluminium Capacitor designed for applications requiring greatest possible capacitance in small physical case sizes. It welds at all critical anode and cathode terminals eliminate riveted or pressure connections to assure freedom from open circuits even when operated in the microvolt or millivolt signal range. It offers low capacitance values in small sizes with axial leads, improved moulded phenolic and seals.
