Type 325/326
–55 ºC to 125 ºC Long-Life, Switching Power Grade Radial
High Temperature and Ultra-Low ESR
The Types 325 and 326 are the ultra-wide-temperature, low-ESR
capacitors for switching power-supply outputs and automotive applications.
The 125 °C capability and exceptionally low ESRs enable high ripple-
current capability. With series inductance of 12 to 16 nH and ripple currents
to 27 amps one of these capacitors can save by replacing eight to ten of the
12.5 mm diameter capacitors routinely at the output of switching power
supplies. Type 325 has three leads for rugged, reverse-proof mounting,
and Type 326 has two leads
.
