United Chemi-Con's KZH series, radial lead-type aluminum electrolytic capacitors are most suitable for output of power supply applications. In recent years, requirements for lower impedance have risen as various electronic units become more functional and higher performance. To correspond to these requirements, we have developed KZH series which has super low ESR and impedance performances as it uses low resistance electrolytes. Compared with the conventional KZE series, KZH series has lower ESR, lower impedance, and longer life times. This can contribute to have lower impedance and longer life of power supplies.
