Key Features

• High Voltage Rating — Rated for 450 V, supporting high‑voltage circuits and applications requiring elevated DC bias handling.
• Capacitance & Tolerance — 82 µF with ±20% tolerance (at 120 Hz, 20°C), providing defined energy storage for filtering and smoothing.
• High Ripple Current — 640 mA at 120 Hz and 960 mA at 10 kHz, enabling effective handling of AC ripple and switching currents in power circuits.
• Long Load Life — Designed for 2000 hours at 105°C under rated conditions, delivering durability for extended thermal stress.
• Wide Operating Temperature — −40°C to +105°C rating for stable operation across common industrial temperature ranges.
• Radial Lead Can Package — Through‑hole radial lead mounting with 7.5 mm lead spacing and compact size (L: 3.15 × D: 1.6 cm) for easy PCB placement and mechanical robustness.
• Environmental Compliance — Compliant to the RoHS Directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Ballast Applications — Sized and specified for ballast use, providing the high voltage rating, ripple tolerance, and load life required in lighting ballast circuits.
• General‑Purpose High‑Voltage Electronics — Useful where compact, high‑voltage bulk capacitance is needed for filtering, energy storage, or DC link smoothing.
• Industrial Power Circuits — Suitable for industrial equipment that requires sustained operation at elevated temperatures up to 105°C and high ripple current handling.

Unique Advantages

• Sustained High‑Temperature Endurance: 2000‑hour load life at 105°C provides predictable performance over extended high‑temperature operation.
• High Ripple Capability: Rated ripple currents (640 mA at 120 Hz, 960 mA at 10 kHz) reduce stress on the capacitor in AC and switching environments, improving system reliability.
• Compact High‑Voltage Solution: 82 µF at 450 V in a miniature radial can (3.15 × 1.6 cm) saves PCB space while delivering substantial energy storage.
• Through‑Hole Robustness: Radial lead mounting and sturdy can construction simplify assembly and provide mechanical stability for heavy‑duty applications.
• Regulatory Compliance: RoHS compliance ensures alignment with current environmental directives for electronic components.
