Key Features

• Capacitance and Voltage — 1000 µF nominal capacitance with a 550 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Screw-Terminal Package — Radial can with screw terminals provides secure, low-resistance connections suitable for high-current power assemblies.
• High Ripple Current Capability — Rated ripple current of 4.3 A at 120 Hz and 6.02 A at 100 kHz for effective filtering and smoothing in high-frequency and low-frequency power stages.
• Operating Temperature Range — Specified for operation from −25°C to +85°C, supporting elevated-temperature industrial environments.
• Endurance and Reliability — For 500 V and 550 V parts, endurance is specified as 5000 hours at +85°C with D.C. bias plus rated ripple current applied; capacitance change remains within ±20%, tan δ ≤ 300% of initial, and leakage current ≤ initial specified value after test.
• Leakage Current Specification — After 5 minutes of rated voltage application, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller (C in µF, V in V).
• Physical Size — Package dimensions include a seated height up to 5.118 in and overall size L: 13 cm × D: 5.1 cm for system mechanical planning.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863); flame-retardant electrolyte versions are available by type.

Typical Applications

• Industrial Power Supplies — Energy storage and smoothing for high-voltage supply rails used in industrial systems where 550 V capability and high ripple tolerance are required.
• Inverter Circuitry — DC-link and filter capacitor in inverter stages, supporting both low-frequency and high-frequency ripple currents.
• High-Voltage Power Modules — Bulk capacitance for extra-high-voltage modules that need secure screw-terminal connections and robust endurance at elevated temperatures.
• General-Purpose High-Ripple Applications — Suitable wherever polarized, high-capacitance aluminum electrolytics are needed to handle sustained ripple current at up to +85°C.

Unique Advantages

• High-Voltage, High-Capacitance Combination: 1000 µF at 550 V provides significant energy storage in a single radial screw-terminal package to reduce component count.
• Designed for High Ripple Environments: Explicit ripple current ratings at 120 Hz and 100 kHz make selection straightforward for both mains-frequency and switching applications.
• Secure Screw-Terminal Connection: Screw terminals enable reliable electrical and mechanical joints for high-current bus connections and serviceability.
• Endurance Under Load: Specified post-test limits (5000 hours at +85°C for 550 V parts) give predictable life and performance for long-running industrial equipment.
• Clear Leakage Limits: Leakage current defined by 3√(C·V) µA or 5 mA after 5 minutes allows designers to size balancing and safety circuits accurately.
• Regulatory and Safety Considerations: RoHS compliance and availability of flame-retardant electrolyte types support regulatory and safety planning.
