Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance at a rated voltage of 450 V, with capacitance tolerance ±20% (at 120 Hz, 20°C).
• High Ripple Capability — Rated ripple current of 8.3 A at 120 Hz and 11.62 A at 100 kHz, supporting heavy ripple environments common in power conversion and inverter circuits.
• Long-Life Endurance — Specified for 20,000 hours of rated ripple-current application at +85°C (endurance criteria restored to 20°C per datasheet), supporting extended service life in continuous-duty systems.
• Temperature Range & Low-Temperature Performance — Operating temperature range −25°C to +85°C, with impedance ratio Z(−25°C)/Z(+20°C) up to 8 as specified for low-temperature stability.
• Package & Termination — Radial can with screw terminals for secure, low-impedance connections in high-current power assemblies; size dimensions L: 10 × D: 7.62 cm for system layout planning.
• Leakage & Dissipation Characteristics — Leakage current specification: after 5 minutes at rated voltage, not more than 3√(C·V) µA or 5 mA (whichever is smaller). Tangent of loss angle (tan δ) is specified per datasheet (measured at 120 Hz, 20°C).
• Safety & Compliance — Flame-retardant electrolyte available to type; compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Polarized Device — Polarized aluminum electrolytic capacitor; follow correct polarity when installing in DC circuits.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy buffering in industrial PSU designs where high-voltage smoothing and long-life operation are required.
• Inverter Circuitry — DC-link smoothing and ripple absorption in inverter and motor-drive power stages benefiting from high ripple current capability.
• High-Voltage Power Modules — Extra-high-voltage applications within the product’s rated range (noting rated voltage of 450 V) that need robust capacitance and endurance.
• General-Purpose Power Filtering — Applications requiring large capacitance and reliable long-term performance in radial can, screw-terminal format for easy integration and secure connections.

Unique Advantages

• High Ripple Endurance: Rated ripple currents (8.3 A at 120 Hz, 11.62 A at 100 kHz) reduce thermal stress and support continuous-duty power-electronics applications.
• Long Service Life: Qualified for 20,000 hours at +85°C under rated ripple conditions, enabling longer maintenance intervals and improved system uptime.
• Secure Screw-Terminal Connection: Screw terminals provide low-impedance, reliable electrical and mechanical connections for high-current assemblies.
• High-Voltage Capability: 450 V rating and series design targeted at extra-high-voltage applications allow use in DC-link and HV smoothing roles.
• Regulatory Compliance: RoHS-compliant materials and optional flame-retardant electrolyte types help meet environmental and safety requirements.
• Measurable Leakage & Loss Parameters: Datasheet-defined leakage-current formula and tan δ measurement conditions aid in precise design margining and component selection.
