DownloadTechnical Datasheet

The T543 series organic SMD Tantalum Capacitor with a conductive polymer cathode capable of delivering very low ESR and improved capacitance retention at high frequencies. KO-CAP combines the low ESR of multilayer ceramic, the high capacitance of aluminium electrolytic and the volumetric efficiency of tantalum into a single surface mount package. Unlike liquid electrolyte-based capacitors, KO-CAP has a very long operational life and high ripple current capabilities. This polymer electrolytic Capacitor is an upscreened version of the industrial T520 KO-CAP. This upscreened option includes surge current testing of 10 cycles at +25°C and 10 cycles at -55°C/+85°C. In addition to 100% Tin (Sn) terminations a Tin-lead (SnPb) option is also available.
