Hiteca™ Class II MLCCs Syfer / Knowles Hiteca™ Class II MLCCs are designed to operate reliably and efficiently in the most demanding applications, optimising power electronics. These high capacitance multilayer ceramic capacitors (MLCCs) offer lower self-heating properties and low loss operations that handle higher ripple currents than conventional ceramic capacitors. A patented dielectric system provides improved capacitance stability and lower parasitic losses under common operating conditions compared to standard Class II dielectrics such as X7R. The series achieves a capacitance ageing rate of 0% per decade and a typical capacitance reduction of <,45% at full rated voltage. Applications for Syfer / Knowles Hiteca Class II MLCCs include power supplies, industrial, automotive / inverter / filtering / smoothing, ripple current smoothing, and snubber capacitors.
