Knowles Precision Devices' new SV series: Stackable performance for power supply applications

Knowles Precision Devices' new SV series: Stackable performance for power supply applications

If you are looking for an alternative to aluminum- and tantalum electrolytic capacitors, then the new Knowles SV Series Capacitors are definitely worth considering as they offer far superior performance to the beforementioned.

These ceramic capacitors can be stacked vertically to form an assembly (of maximum 10 pieces of the same size) with various lead configurations to safeguard them against thermal- and mechanical stress and are 100 percent tested for dielectric withstanding voltage, insulation resistance, capacitance, and dissipation factor.

By stacking the capacitor the required capacitance up to 200 µF can be reached without having to make concessions on the footprint of your board. All capacitors in this series currently come in a 2220 configuration and with the X7R dielectric, which offers a high capacitance-to-volume ratio.

Additionally, the low equivalent series resistance (ESR) and low equivalent series inductance (ESL) are inherent to the SV Series design, which gives the assemblies the capability to handle high ripple currents at high frequencies. Since ripple current can cause self-heating (I2R) losses and degradation in a capacitor, reducing ESR helps minimize these impacts, resulting in less power loss and improved reliability.

Together, these qualities make the SV Series ideally suited for the input and output stages of switch mode power supplies, power supply filtering and DC-DC converters.
