Tantalum Capacitors Selection Guide

Tantalum capacitors are constructed using tantalum for at least the anode material.Capacitors in general consist of two polarized conductors separated by an insulating dielectric material. When the component is connected to a voltage source, its negative conductor becomes saturated with electrons, therefore charging the capacitor Get price

Tantalum vs Ceramic Capacitors

Jul 03, 20121 - tantalum prices rose significantly and lead times became quite long. 2 - MLCC ceramic capacitor technology advanced to the point where large bulk capacitor values became available at low cost. 3 - we had several instances of high failure rate of tantalums due to surge current. Tantalums are prone to this failure, ceramics are not. Get price
