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 Highlights
- 2000 hour life test at 125 °C
- Ripple Current to 27 amps
- ESRs to 5 mΩ
- > 90% capacitance at –40 °C
