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

still occur. Accordingly, customer applications which require a high degree of reliability or safety should
employ suitable designs or other safeguards (such as installation of protective circuitry or redundancies
or other appropriate protective measures) in order to ensure that the failure of an electrical component
does not result in a risk of personal injury or property damage. Although all product-related warnings,
cautions and notes must be observed, the customer should not assume that all safety measures are indi-
cated in such warnings, cautions and notes, or that other safety measures may not be required.
