Thin film capacitor terminal

Abstract

The invention relates to a thin film capacitor terminal. The terminal comprises, by weight, 8-10 parts of copper, 3-5 parts of platinum, 0.5-1parts of rhodium, 0.02-0.08 parts of iridium, 0.28-0.44 parts of ruthenium, 2-8 parts of boron, 0.4-0.6 parts of titanium, 0.8-1 parts of zirconium, 0.03-0.09 parts of hafnium and 2-4 parts of zinc. The capacitor terminal provided in the invention has high acid and alkali resistance performance. Under a strong acid or alkali environment, the terminal is not easy to be corroded and damaged so that a phenomenon of poor contact of the capacitor is avoided.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to film capacitor terminals. Background technique [0002] Capacitors are usually called capacitance, and capacitance is also called "capacitance", which refers to the amount of charge stored under a given potential difference, denoted as C, and the international unit is farad (F). Generally speaking, charges will move under force in an electric field. When there is a medium between conductors, it will hinder the movement of charges and cause charges to accumulate on the conductors, resulting in the accumulation and storage of charges. The amount of stored charges is called capacitance. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc. [0003] Film capacitor is a kind of capacitor with superior performance, which has the fol...

Problems solved by technology

The terminals of film capacitors in the prior art are generally made of metal materials directly. If they are used in a strong acid or alkali environment, the terminals are easily corroded and damaged, resulting in poor contact of the capacitor.
