The Effect of Macroheterocyclic Compounds and Their Metallocomplexes on Temperature-Frequency Characteristics of Aluminum Oxide Electrolytic Capacitors

Resumo

The effect of addition of mactoheterocyclic compounds of the ABAB and A′BBB types, in which A (1,3-phenylene or 2,6-pyridine)moiety, A′ (1,3-phenylene)moiety, and A′ (1,3-isoindoline)moiety are interlinked by aza-bridges, and also of their complexes with copper(II) and cobalt(II) on the temperature-frequency characteristics of small-scale aluminum oxide capacitors with the vertical chip design is studied in the temperature range from −60°C to +100°C and the frequency range from 50 Hz to 200 kHz. It is shown that under conditions studied, the addition of macroheterocycles and their complexes decreases the resistance and the leakage currents of capacitor.
