Key Features

• Capacitance & Tolerance — 1.8 mF (1800 µF) with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating — Rated voltage of 450 V for extra-high-voltage power designs.
• Screw Terminal Mounting — Radial can package with screw terminals for robust, low-resistance connections in power assemblies.
• Long Life — Endurance specified as 20,000 hours at 85°C under rated ripple-current conditions; capacitors meet specified capacitance, dissipation factor and leakage after endurance testing.
• High Ripple Current — Rated ripple handling of 6.1 A at 120 Hz and 8.54 A at 100 kHz to support heavy AC ripple on high-voltage rails.
• Operating Temperature Range — Specified for use from −25°C to +85°C.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller.
• Polarized — Designed for DC applications requiring polarized electrolytic capacitance.
• Series-level Options — Series documentation indicates availability of flame-retardant electrolyte types and extended size ranges (refer to series datasheet for options).
• Package Dimensions — Size dimension listed as L: 9 × D: 6.35 cm in the product specifications.

Typical Applications

• Industrial Power Supplies — Used for high-voltage smoothing and energy buffering in industrial power supplies and control systems.
• Inverter Circuits — Suitable for DC link and smoothing in inverter circuitry where high ripple current and long life are required.
• High-Voltage Power Electronics — Employed for bulk capacitance and ripple suppression on extra-high-voltage rails in power conversion equipment.

Unique Advantages

• Extended operational life: 20,000 hours at +85°C under rated ripple conditions provides predictable long-term performance for industrial installations.
• High ripple handling capability: Specified ripple currents of 6.1 A (120 Hz) and 8.54 A (100 kHz) reduce heating and extend service life in heavy-duty applications.
