Key Features

• High Capacitance: 18 000 µF (18 mF) bulk capacitance for energy storage and smoothing in DC power rails.
• 350 V Rated Voltage: Rated for 350 V DC operation to support higher-voltage bus applications.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low-resistance connections for high-current systems and straightforward installation.
• Wide Operating Temperature: Specified for −40 °C to +85 °C operation to cover a broad range of industrial ambient conditions.
• Endurance at Elevated Temperature: Load life of 2000 hours at 85 °C with application of ripple current, with post-test requirements defined for capacitance, tan δ and leakage current.
• High Ripple Current Capability: Rated ripple currents of 31.1 A at 120 Hz and 43.54 A at 10 kHz, enabling effective handling of AC ripple in high-power designs.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is specified as not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C).
• Insulation & Voltage Proof: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; no abnormality under AC 2500 V for 1 minute between terminal and bracket.
• Polarized Construction & Tolerance: Polarized capacitor with capacitance tolerance of ±20% (120 Hz, 20 °C).
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies: Bulk energy storage and smoothing on DC bus lines for industrial and commercial power supplies that require large capacitance at elevated voltages.
• Inverters and Motor Drives: Filtering and ripple handling in inverter DC-link and motor drive circuits where high ripple current capability and secure screw-terminal connections are needed.
• UPS and Power Conditioning: Energy buffering and decoupling in uninterruptible power supplies and power-conditioning equipment to maintain stable DC rails.

Unique Advantages

• Compact high-capacitance solution: 18 000 µF in a screw-terminal radial can supports equipment downsizing by providing substantial bulk capacitance in a single component.
• Designed for high ripple loads: Specified ripple current ratings at 120 Hz and 10 kHz reduce the need for parallel components and simplify thermal management.
• Robust mechanical connection: Screw terminals offer reliable, low-resistance electrical connections suited to high-current assemblies.
• High-voltage capability: 350 V rating and series-level support up to 450 V allow use on higher-voltage DC buses common in industrial power systems.
• Measured reliability parameters: Defined leakage current, insulation resistance, voltage proof and a 2000 h endurance rating at 85 °C provide verifiable performance data for design validation.
• Regulatory compliance: RoHS conformity supports designs requiring restricted-substance compliance.
