Type 330
–55 °C to 105 °C Ultra-Long-Life, Switching Power Grade Radial
High Ripple and Ultra-Long Life
The Type 330 is the ultra-long-life version of the Type 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 stiffening. 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.
