Compared to standard 105 °C snap-ins like the Type 381L/LX
Type 381LR can handle an extra 25% ripple current or more. This
remarkable capability stems from advances in electrolyte that give
extremely low ESR values.In high ripple current applications like
motor drives you can save by using fewer capacitors.
Highlights
The right choice for motor drive bus capacitors
The right choice for UPS bus capacitors
