Key Features

• High Capacitance at High Voltage — 3.3 mF (3300 µF) nominal capacitance with a 450 V rated voltage for bulk energy storage and high-voltage filtering.
• Load Life — Rated for 2000 hours at 85°C with rated ripple current applied, supporting sustained performance under continuous load conditions.
• Wide Operating Temperature Range — Specified for operation from −40°C to +85°C to accommodate a broad range of industrial environments.
• Ripple Current Capability — 11.1 A at 120 Hz and 15.54 A at 10 kHz, enabling handling of significant AC ripple in power conversion and filtering applications.
• Capacitance Tolerance — ±20% (measured at 120 Hz, 20°C), providing predictable electrical performance for design calculations.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√CV (µA) or 5 mA, whichever is smaller (measured at 20°C).
• Robust Terminal Design — Screw terminal mounting with nominal M5 bolt sizing (for φ51 cases) for stable, high-current connections.
• Mechanical Size — φ51 × 170 mm can size (diameter × length) for axial footprint planning in compact power assemblies.
• RoHS Compliant — Manufactured in accordance with RoHS requirements (2011/65/EU, (EU)2015/863).
• Electrical Safety Characteristics — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute without abnormality between terminal and bracket.
• Low-Temperature Stability — Impedance ratio Z(−40°C)/Z(+20°C) ≤ 12, supporting performance at cold ambient conditions.

Typical Applications

• High-voltage power supplies — Bulk smoothing and energy storage where a 450 V rating and multi-millifarad capacitance are required.
• Power conversion and DC-link circuits — DC-link smoothing and ripple attenuation in compact power conversion modules benefiting from high capacitance and defined ripple current capability.
• Industrial equipment — General-purpose filtering and energy buffering in industrial systems that require durable screw-terminal connections and operation across −40°C to +85°C.

Unique Advantages

• High-energy density for downsized equipment — 3.3 mF at 450 V supports reduced component count and smaller power assemblies during equipment downsizing.
• Defined endurance under ripple load — 2000-hour life at 85°C with rated ripple current gives designers a clear qualification baseline for lifetime planning.
• Screw-terminal security — M5-compatible screw terminals provide mechanically robust, low-resistance connections for high-current installations.
• Measurable ripple performance — Specified ripple current values at 120 Hz and 10 kHz let engineers size thermal and cooling provisions accurately.
• Wide ambient tolerance — −40°C to +85°C operating range and low-temperature impedance data support reliable operation across varied environments.
• Compliance and safety metrics — RoHS compliance and specified insulation resistance and voltage-proof levels assist in regulatory and safety assessments.
