Knowles Precision Devices’ newest line of multilayer ceramic capacitors (MLCCs) built with Hiteca™ can deliver high capacitance stability over high temperature and voltage as well as lower parasitic losses under common operating conditions.
The Hiteca™ is a low loss, semi-stable Class II dielectric that features improved capacitance stability, low equivalent series resistance (ESR) and equivalent series inductance (ESL), 0 percent aging rate with no loss of capacitance over time, and a typical capacitance reduction of <45 percent at full rated voltage.
With lower self-heating properties and low loss operation, these capacitors can handle higher ripple currents than conventional ceramic capacitors. This unique combination of qualities makes Hiteca™ MLCCs the perfect choice for applications such as DC bus smoothing, while their non-piezo construction makes them ideal for use as snubber capacitors

The table shows the maximum and minimum capacitance values measured, and the bias voltage at which those values were obtained. The Hiteca™ provides the highest capacitance at 600Vdc applied bias, despite having the lowest capacitance rating.
The Hiteca™ MLCCs can help customers optimize their power electronics, as they are designed to operate reliably and efficiently, even in the most demanding applications.
