UCA2W220MHD6

The UCA2W220MHD6 is a Nichicon UCA series aluminum electrolytic capacitor in a radial lead can package. It provides 22 µF capacitance at a 450 V rating in a compact, miniature form factor intended for general-purpose high-voltage applications.

Designed for use in power supply and ballast applications, the part combines high ripple-current capability with long life performance to support reliable filtering and energy buffering in high-voltage circuits.

Key Features

• Electrical Characteristics — 22 µF nominal capacitance with ±20% tolerance and a rated voltage of 450 V; polarized design for conventional electrolytic circuit use.
• High Ripple Current — Rated ripple current of 280 mA at 120 Hz and 560 mA at 100 kHz, enabling improved handling of AC ripple in power circuits.
• Long Life / Endurance — Load-life specification of 12,000 hours at +105°C, providing extended service life under rated conditions.
• Temperature Range — Operates from −25°C to +105°C to suit a broad set of environmental conditions.
• Leakage and Loss — Leakage current specified as not more than 0.04CV + 100 µA after one minute at 20°C; tangent of loss angle (tan δ) ≤ 0.20 at 450 V (measured at 120 Hz, 20°C).
• Compact Radial Package — Radial lead, can-style package with 7.5 mm lead spacing and physical dimensions L: 2.0 cm × D: 1.8 cm for space-efficient through-hole mounting.
• RoHS Compliant — Conforms to RoHS requirements for regulatory compliance in lead-restricted assemblies.

Typical Applications

• Power Supplies — AC ripple filtering and DC smoothing in high-voltage power supply stages where 450 V capability and high ripple current are required.
• Ballasts and Lighting — Energy buffering and ripple management in ballast and lamp driver circuits, consistent with the series’ stated suitability for ballast applications.
• General-Purpose High-Voltage Circuits — Through-hole, high-voltage filtering and decoupling in industrial and commercial equipment that use radial-leaded capacitors.

Unique Advantages

• Miniature high-voltage footprint — 22 µF at 450 V in a compact 2.0 cm × 1.8 cm can supports space-constrained designs that still require high voltage capability.
• High ripple-current capability — Specified ripple ratings (280 mA at 120 Hz; 560 mA at 100 kHz) help manage internal heating and improve system reliability under ripple stress.
• Extended operational life — 12,000 hours at +105°C endurance supports longer maintenance intervals and predictable lifecycle planning.
• Through-hole, robust mounting — Radial lead configuration with 7.5 mm lead spacing provides secure mechanical retention for applications where board-level stability matters.
• Measured loss and leakage data — Clear tan δ and leakage current specifications enable predictable performance modeling and thermal design.
• Regulatory compliance — RoHS-compliant construction simplifies integration into lead-restricted assemblies.
