Filtering power of 3 or more tantalum chips and 50 year life
Solid polymer aluminum capacitors combine the high capacitance make them ideal for bypassing high
capacitance capability of an electrolytic component frequency noise, and for switching frequency filtering
with the high frequency performance of film capacitors. in DC/ DC conversion. SPA capacitors are packaged in
When the need for low impedance at high frequency is a molded resin case with the same footprint (7.3x4.3
critical for your design, one SPA chip is capable of mm) as the industry standard tantalum “D” and “E”
replacing several liquid electrolyte aluminum or case sizes. The solid electrolyte results in a capacitor
tantalum capacitors connected in parallel. This is due with stable impedance and equivalent series resistance
to the ultra-low e.s.r. which results in significantly lower over the entire operating temperature range and they
impedance than either aluminum or tantalum have more than twice the ripple current handling
