  Supports up to 450 V DC for high-voltage filtering and energy-storage roles.
• Capacitance and Tolerance — 33 µF ±20%
  Standard capacitance with ±20% tolerance measured at 120 Hz, 20°C for predictable filtering performance.
• Long Endurance at Elevated Temperature
  Rated for 12,000 hours of load life at +105°C under DC bias plus rated ripple current, supporting prolonged high-temperature operation.
• High Ripple Current Capability
  Low-frequency ripple current 350 mA (120 Hz) and high-frequency ripple current 700 mA (100 kHz) for effective smoothing under varying switching conditions.
• Controlled Dissipation Factor
  tan δ (DF) max 0.20 measured at 20°C, 120 Hz, enabling assessment of loss and thermal behavior.
• Leakage Current Specified
  Leakage current calculated to 694 µA after 1 minute at 20°C, enabling predictable leakage budgeting in designs.
• Compact Radial Package
  Case size φ18 × 25 mm (D × L) in a radial can with 7.5 mm lead spacing and 0.8 mm lead diameter, compatible with traditional through-hole assembly and hand/soldering processes.
• Wide Operating Temperature Range
  Rated for −25°C to +105°C to cover a broad set of industrial and commercial environments.
• RoHS Compliant
  Manufactured in compliance with RoHS requirements.
• Packaging Options
  Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly handling.

Typical Applications

• Power Supplies — Bulk and output filtering in high-voltage power supplies where 450 V rating and high ripple tolerance are required.
• Ballast Circuits — Smoothing and energy storage in ballast and lamp-driver designs that demand long life at elevated temperature.
• General-Purpose High-Voltage Electronics — Decoupling and smoothing in industrial and commercial high-voltage circuits using a compact radial-lead form factor.
