Key Features

• Capacitance & Rated Voltage — 6800 µF (6.8 mF) nominal capacitance, rated for 400 V operation.
• Screw Terminal Mounting — Radial can with screw terminals for secure, high-current connections consistent with the capacitor’s ripple-current ratings.
• High Ripple Current — Rated ripple current: 26.3 A at 120 Hz (low frequency) and 36.82 A at 100 kHz (high frequency), supporting demanding power-electronics stress.
• Load Life — Rated for 5000 hours of operation at 85°C when subjected to rated ripple current and DC bias.
• Operating Temperature Range — Specified for –40°C to +85°C operation.
• Package Size — φ90×90L (approx. L: 9 cm × D: 9 cm) radial can format designed for compact power assemblies; available with three-leg brackets as applicable.
• Electrical Characteristics — Polarized capacitor with capacitance tolerance of ±20% and leakage current specified per series test conditions (after 5 minutes’ application of rated voltage: ≤ 3√V µA or 5 mA, whichever is smaller).
• Endurance & Charge–Discharge — Endurance tests include 5000-hour life under DC bias plus ripple at 85°C and charge–discharge endurance testing documented in series specifications.
• RoHS Compliant — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Packaging — Supplied in cardboard packing for mass-production shipment.

Typical Applications

• Industrial Power Supplies — For inverter circuitry and bulk energy storage where sustained ripple handling and long life at elevated temperatures are required.
• AC Servo Drives & Motor Control — Supports high-frequency regenerative voltage and rapid charge–discharge cycles common in servo and drive systems.
• Regenerative Braking Systems — Suitable for high-frequency regenerative voltage applications that demand substantial ripple-current capability.
• High-Frequency Power Electronics — Appropriate where elevated ripple currents at kHz-range switching frequencies are present and long-term endurance is important.

Unique Advantages

• High ripple-current capability: Specified at 26.3 A (120 Hz) and 36.82 A (100 kHz), enabling reliable operation under heavy AC stress.
• Long operational life at elevated temperature: 5000 hours at 85°C under rated ripple and DC bias provides predictable durability in demanding environments.
• Compact, screw-terminal can format: φ90×90L radial can with screw terminals combines a smaller physical footprint for its class with robust connection points for power assemblies.
• Designed for high-frequency charge–discharge: Series-level specifications include endurance for rapid charge–discharge cycles, supporting systems with frequent voltage swings.
• Clear electrical limits and leakage specification: Leakage current defined as ≤ 3√V µA or 5 mA (whichever is smaller) after initial voltage application, aiding predictable system design.
• Regulatory compliance: RoHS compliance simplifies selection for regions and designs requiring restricted substance adherence.
