High Ripple and Ultra-Long Life

TheType 330 is the ultra-long-life version of theType 300 capacitor.

With an astonishing, 50,000-hour

expected life operating

continuously at full load and 65 ºC the 330 is the choice for power

supply outputs and UPS battery stifening. The exceptionally low

ESRs enable high ripple-current capability. With series inductance

of 12 to 16 nH and ripple currents to 16 amps one of these

capacitors can save by replacing three or four of the 12.5 mm

diameter capacitors routinely at the output of switching power

supplies. Type 330 R delivers even lower ESR and higher ripple.

Type 330 has three leads for rugged, reverse-proof mounting. Two

leads are available as Types 331 and 331R.

Highlights

• Expected Life > 20 years @ 45 °C

• Ripple Current to 16 amps

• ESRs to 6

mΩ

• > 90% capacitance at –40 °C

• Replaces multiple capacitors

RoHS Compliant
