Type 300/301 –55 ºC to 105 ºC Long-Life, Switching Power Grade Radial
High Capacitance and
Ultra-Low ESR
The Types 300 and 301 are the wide-temperature, low-ESR capaci-
tors for power-supply outputs and UPS battery stiffening. The ex-
ceptionally low ESRs enable high ripple-current capability. With
series inductance of 12 to 16 n Hand 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 300 has three leads for rugged, reverse-proof mount-
ing, and Type 301 has two leads. Types 300R and 301R deliver even
lower ESR and higher ripple.
