SPA Capacitors
Solid Polymer Aluminum Surface Mount Capacitors
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 SPA chip is capable of
replacing several liquid electrolyte aluminum or
tantalum capacitors connected in parallel. This is due
to the ultra-low e.s.r. 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 e.s.r. and high
capacitance make them ideal for bypassing high
frequency noise, and for switching frequency filtering
in DC/ DC conversion. SPA capacitors are packaged in
a molded resin case with the same footprint (7.3x4.3
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.
