Type 381LR 105 °C Highest Ripple, Snap-In Aluminum
Ultra-High Ripple Capabilities
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
- Compare to Type 381L
- Up to 2 times the ripple current
