Key Features

• High Rated Voltage — 500 V rated voltage for demanding DC applications that require high‑voltage energy storage and filtering.
• Large Capacitance — 1.2 mF (1200 µF) nominal capacitance with ±20% tolerance for effective bulk smoothing and decoupling.
• Screw Terminal Mounting — Radial can with screw terminals (M5 nominal bolt) for secure, low‑impedance power connections and easy mechanical installation.
• Ripple Current Capability — Supports 6.2 A at 120 Hz (low frequency) and 8.68 A at 10 kHz (high frequency) for reliable operation under AC ripple stress.
• Endurance and Temperature Range — 5000 hours at 85°C rated life and an operating temperature range of −25°C to +85°C for sustained performance in industrial environments.
• Leakage and Loss Characteristics — Specified leakage current of approximately 2320 µA and tan δ of 0.2, enabling predictable power dissipation and behavior under DC bias.
• Compact, Defined Form Factor — ϕ51 × 115 mm (L: 11.5 cm × D: 5.1 cm) can dimension for integration where a φ51 screw‑terminal can size is required.
• RoHS Compliant — Built to meet RoHS directive requirements for environmental compliance.

Typical Applications

• High‑Voltage Power Supplies — Bulk filtering and energy storage in DC power rails where 500 V rating and high capacitance are required.
• Power Conversion and Inverters — DC link and smoothing duties in industrial power conversion modules that demand high ripple current capability and long life.
• Industrial Equipment — General‑purpose energy storage and filtering for heavy equipment and control systems operating within −25°C to +85°C.

Unique Advantages

• High‑Voltage, High‑Capacitance Combination: Delivers 1200 µF at 500 V to support substantial energy storage in a single component, reducing the need for parallel devices.
• Screw‑Terminal Reliability: Robust screw terminal interface provides secure electrical and mechanical connection for high‑current installations.
• Strong Ripple Handling: Specified ripple currents at both low and high frequencies (6.2 A at 120 Hz, 8.68 A at 10 kHz) help maintain capacitor temperature and longevity under ripple stress.
• Proven Endurance: 5000 hours rated life at 85°C offers predictable long‑term performance for continuous industrial operation.
• Measured Electrical Behavior: Specified leakage current (~2320 µA) and tan δ (0.2) provide predictable loss and leakage characteristics for thermal and circuit budgeting.
• Regulatory Compliance: RoHS compliance supports integration into assemblies that require restricted‑substance conformity.
