381LR

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.
This type has four unique highlights. The first one is that it is the right chioce for motor dirve bus capacitors.The second one is that it is the right choice for UPS bus capacitors. The third one is that it is compare to Type 381L. The forth one is up to 2 times the ripple current.
Otherwise, there are some specifications about 381LR. Operating Temperature is 40 °C to + 105 °C when the voltage is equal to or less than 315 V or -25°C to + 105°C when the voltage is up to 350 V. Rated Voltage is 200 Vdc to 450 Vdc. Capacitance is 56 F to 2,200 F (± 20%). Leakage Current is less than or equal to 3 CV A(at 5 minutes).
