• High‑Temperature Endurance: Rated for operation from −40°C to +105°C with a specified load life of 5000 hours at 105°C.
• High Ripple Current Capability: 15 A at 120 Hz (low frequency) and 21 A at 10 kHz (high frequency) to support heavy AC ripple and switching loads.
• Low Loss Characteristics: Specified tan δ of 0.2, supporting lower dissipation under AC conditions.
• Leakage Current: Characterized leakage current of 3650 µA for predictable standby and bias performance.
• Screw Terminal Package: Radial can with screw terminals for secure electrical and mechanical connections in high‑power assemblies.
• Compact Mechanical Footprint: 63.5 mm diameter × 120 mm length (φ63.5 × L120 mm), supplied in cardboard packing for mass production handling.
• Standards & Compliance: RoHS‑compliant construction.

Typical Applications

• Industrial Power Supplies: Bulk DC energy storage and smoothing where 450 V rating and high ripple current are required for inverter front ends and converters.
• Inverter & Motor Drive Systems: Supports regenerative voltage and high‑frequency switching in AC servomotor drives and general inverter applications.
• High‑Frequency Charge/Discharge Circuits: Suited for circuits that demand frequent charge‑discharge cycles and fast energy transfer, backed by the capacitor’s endurance specifications.
