Type ESRD
Solid Polymer Aluminum SMT Capacitors
Filtering power of 3 or more tantalum chips and 50 year life
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.
