Improved ESR on MnO2 Tantalum Capacitors at Wide Voltage Range

One common trend in switch-mode power supply, micro-processor, and digital circuit applications is to achieve reduced noise while operating at higher frequencies. In order to realize this, components with low Equivalent Series Resistance (ESR), high capacitance and high reliability are required. A new generation of Low ESR tantalum chip capacitors has been developed utilizing a low resistivity MnO2 electrolyte that enables very low component ESR. MnO2 technology provides excellent field performance, environmental stability and high electrical and thermal stress resistance in wide voltage range from four to thirty-five volts. The capacitors are designed for operation in temperatures up to 125°C. Tantalum capacitor technology has many characteristics ideal for filtering applications in DC/DC converters, power supplies and other applications
