Key Features

• Capacitance & Voltage — 82 µF rated capacitance at 450 V, suitable for high-voltage bulk and filtering roles in power circuits.
• Long-Life Endurance — Designed to withstand rated ripple current for 5000 hours at 105°C (series long-life assurance), providing predictable performance under continuous high-temperature stress.
• High Operating Temperature — Rated for operation from −25°C to +105°C, enabling use in elevated-temperature power environments.
• Ripple Current Capability — Specified ripple handling of 590 mA at 120 Hz and 843.7 mA at 50 kHz, allowing effective smoothing of rectified and high-frequency switching waveforms.
• Low Leakage Specification — Leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20°C, supporting predictable bias conditions after voltage application.
• Compact Snap-in Package — Radial, snap-in can package with compact footprint (L: 2.5 × D: 2.2 cm) for secure PCB mounting in power assemblies.
• Series Characteristics — Benefits from LGX series specifications, including tan δ max 0.20 for 450–500 V (measurement at 120 Hz, 20°C) and low-temperature impedance stability data for reliable low-temperature performance.
• RoHS Compliant — Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter Rectifier Stages — Used in rectifier circuits for general inverters to provide bulk energy storage and smoothing under continuous ripple and elevated temperatures.
• Switching Power Supplies — Acts as a high-voltage filter and bulk capacitor in switching supplies where sustained ripple current and thermal endurance are required.
• General Power Circuits — Suitable for a variety of industrial and commercial power applications requiring a compact 450 V electrolytic with long-life rating.

Unique Advantages

• Extended High-Temperature Reliability: 5000-hour endurance at 105°C assures designers of sustained performance in hot operating environments.
• Measured Ripple Handling: Explicit ripple current ratings at both 120 Hz and 50 kHz enable confident selection for both mains-rectified and switching-frequency applications.
• Predictable Leakage Behavior: Leakage defined by a standard formula (I ≤ 3√CV) provides repeatable post-voltage-application characteristics for predictable designs.
• Space-Efficient Snap-in Mounting: Radial snap-in can offers a secure board attachment and a compact footprint for dense power assemblies.
• Series-Tested Electrical Limits: Series specifications for tan δ and impedance stability at low temperature give clear electrical boundaries for design verification.
• Regulatory Compliance: RoHS conformity supports use in products requiring restricted substance compliance.
