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 Specifications Temperature Range –40 °C to + 105 °C ≤ 315 Vdc –25 °C to + 105 °C ≥ 350 Vdc Rated Voltage Range 200 Vdc to 450 Vdc Capacitance Range 56 µF to 2,200 µF Capacitance Tolerance ± 20% Leakage Current ≤3 √CV µA, 4 mA max, 5 minutes Ripple Current Multipliers Ambient Temperature 45 ºC 60 ºC 70 ºC 85 ºC 105 ºC 2.35 2.20 2.00 1.70 1.00 Frequency 10 50 Hz 60 Hz 120 Hz 500 kHz 1 kHz kHz & Up 0.75 0.80 1.00 1.20 1.25 1.40 Low Temperature Characteristics Impedance ratio: Z–20⁰C ∕ Z+25⁰C ≤ 3 (200–450Vdc) Endurance Life Test 3000 h at full load at 105 °C ∆ Capacitance ±20% ESR 200% of limit DCL 100% of limit Shelf Life Test 1000 h at 105 °C ∆ Capacitance ±20% ESR 200% of limit DCL 100% of limit Vibration 10 to 55 Hz, 0.06” and 10 g max, 2 h each plane RoHS Compliant CDM Cornell Dubilier • 140 Technology Place • Liberty, SC 29657 • Phone: (864)843-2277 • Fax: (864)843-3800 Type 381LR 105 °C Highest Ripple, Snap-In Aluminum Ultra-High Ripple Capabilities Part Numbering System 381LR 271 M 200 Type Cap Tolerance Voltage 381LR 271 = 270 µF M = ±20% 160 = 160 Vdc 222 = 2200 µF H01 2 +D Case Insulating Blank = no end disk if
