Lot Code

Solid Polymer Aluminum capacitors combine the high capacitance capability of an

electrolytic component with the high frequency performance of film capacitors. When

the need for low impedance at high frequency is critical for your design, one ESRD

chip is capable of replacing several liquid electrolyte aluminum or tantalum capacitors

connected in parallel. This is due to the ultra-low ESR which results in significantly

lower impedance than either aluminum or tantalum capacitors at frequencies of 100

kHz and above. There is no longer a need to stack capacitors to lower the impedance at

high frequency. The low ESR and high capacitance make them ideal for bypassing high

frequency noise, and for switching frequency filtering in DC/ DC conversion. ESRD

capacitors are packaged in a molded resin case with the same footprint (7.3 x 4.3 mm)

as the industry standard tantalum “D” and “E” case sizes. The solid electrolyte results

in a capacitor with stable impedance and equivalent series resistance over the entire

operating temperature range and they have more than twice the ripple current handling

capability of tantalum capacitors. In addition, the solid electrolyte delivers a typical

expected operating life of more than 50 years, and it is ignition free.
