381LR Datasheet, PDF (1/3 Pages) List of Unclassifed Manufacturers – 105 °C Ultra-High-Ripple Snap-in

Type 381LR 105 °C Ultra-High-Ripple Snap-in
25% More Ripple Current Capability
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
Specifications
• 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
