• Endurance: Load-life rated for 2000 hours at 85°C with rated ripple current applied, supporting sustained operation under continuous stress.
• High Ripple Current Capability: 10.8 A at 120 Hz (low frequency) and 15.12 A at 10 kHz (high frequency) to handle significant AC content on DC rails.
• Leakage and Loss Characteristics: Specified leakage current of 3300 µA and tan δ of 0.25 for predictable behavior in power designs; capacitance tolerance ±20% (120 Hz, 20°C).
• Compact, Serviceable Package: φ63.5 × 90 mm body (L: 9.0 × D: 6.35 cm) with M5 bolt compatibility for standard mounting brackets.
• Regulatory Compliance: RoHS compliant for restricted-substance requirements.

Typical Applications

• Power supply bulk smoothing: Provides high-voltage bulk capacitance for smoothing and energy buffering in 450 V DC rails.
• PFC and intermediate DC link support: Handles significant ripple current at both low and high frequencies to stabilize intermediate DC links and power-factor circuits.
• Industrial equipment: Suited for general-purpose industrial control and power electronics that require durable, serviceable capacitors and long operating life.
• Equipment downsizing efforts: Higher capacitance in a screw-terminal package helps designers reduce overall system footprint while maintaining energy storage requirements.

Unique Advantages

• High-voltage capability at high capacitance: 450 V and 2700 µF combine to deliver substantial stored energy for demanding DC systems.
• Robust ripple handling: 10.8 A (120 Hz) and 15.12 A (10 kHz) ripple ratings allow the capacitor to absorb AC components without derating system performance.
• Screw-terminal reliability: Mechanical and electrical robustness for secure connections in high-current installations and ease of field replacement.
• Designed for continuous operation: 2000-hour endurance at 85°C under rated ripple current supports long-term reliability in sustained-duty applications.
• predictable electrical parameters: Specified tan δ (0.25) and leakage current (3300 µA) give engineers measurable characteristics for circuit design and modeling.
