Low Impedance Ta Capacitors to Serve the Needs of the Electronics Industry


Randy Hahn, and Jonathan Paulsen - KEMET Electronics Corp


Trends in circuit design for miniature consumer electronics are driving the need for very low impedance capacitors. Increasingly complex ICs requiring higher current and operating at higher frequencies have led to a need to reduce operating voltages to minimize heat buildup. All of these factors contribute to the need for low impedance decoupling capacitors. In order to meet the challenges posed by the changes in circuit design passive component manufacturers have increased capacitance density and reduced ESR and ESL. This paper reviews enabling technologies currently being used, as well as those being developed, by tantalum component manufacturers to continue to provide low cost solutions to fulfill the needs of the electronics industry.
