KEMET's T521 Series KO-CAP Organic Polymer Tantalum Capacitor features voltage ratings up to 63V and capacitance values up to 330µF, high ripple current capability, safe failure mode, and low ESR. The KEMET T521 Series High Voltage Polymer Tantalum Capacitor
is volumetrically efficient, has stable temperature
Pb Free when ordered with 100% Sn Termination Finish, RoHS
and halogen free. This series is designed for DC/DC
converters, power supply input and higher application voltages such as
12V, 24V, 28V, and 48V input rails.
The T521 KO-CAP Series features a Ta anode and Ta₂O₅ dielectric as well as a conductive organic polymer that replaces the traditionally used MnO₂ as the cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency.
