UCA2W220MHD

The UCA2W220MHD is a miniature aluminum electrolytic capacitor from Nichicon's UCA series, configured as a radial-lead, polar can for general-purpose power applications. It provides 22 µF capacitance at a 450 V rating, designed for use in power supplies, ballasts and other industrial power circuits.

Key performance attributes include high ripple-current capability and long load life (12,000 hours at 105°C). The component is RoHS-compliant. Status: End Of Life — availability may be limited; verify stock and suitability for new designs.

Key Features

• Core Type  Miniature aluminum electrolytic capacitor, radial lead can suitable for through-hole mounting.
• Capacitance & Voltage  22 µF rated capacitance with a 450 V rated voltage, intended for higher-voltage power rails.
• Tolerance & Polarization  Capacitance tolerance −20% to +20% at 120 Hz, 20°C; polarized device.
• Loss Tangent (tan δ)  tanδ = 0.2 (measured at 20°C, 120 Hz), enabling predictable ESR behavior at specified conditions.
• Leakage Current  Leakage current specified at 496 µA (measurement condition: 20°C, after 1 minute application of rated voltage).
• High Ripple Current Handling  Low-frequency ripple: 280 mA at 120 Hz; high-frequency ripple: 560 mA at 100 kHz — suitable for switching and high-frequency power stages.
• Long Endurance  Load-life rating of 12,000 hours at +105°C under rated voltage and ripple conditions.
• Temperature Range  Operational range −25°C to +105°C for varied industrial environments.
• Package & Dimensions  φ16 × 25 mm can (L = 25 mm, D = 16 mm / 2.5 × 1.6 cm), radial lead spacing 7.5 mm (lead spacing tolerance ±0.5 mm), lead diameter 0.8 mm.
• Packaging Options  Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly handling.
• Compliance  RoHS-compliant per provided product data.

Typical Applications

• Power Supplies  Filtering and smoothing on high-voltage rails in AC/DC and DC/DC power supplies where 450 V ratings and ripple handling are required.
• Ballasts and Lighting Drivers  Energy storage and ripple damping in lighting ballast circuits, consistent with the UCA series’ suitability for ballast applications.
• General-Purpose Industrial Power Circuits  Decoupling and bulk capacitance in industrial control and power-conditioning equipment.

Unique Advantages

• High Voltage Capability: The 450 V rating supports higher-voltage power rails without the need for series capacitor arrangements.
• High Ripple Endurance: Specified ripple current ratings (280 mA at 120 Hz; 560 mA at 100 kHz) make the part suitable for both low- and high-frequency switching environments.
• Long Operational Life: 12,000 hours at 105°C under rated conditions reduces replacement frequency in continuous-duty installations.
• Compact Radial Package: φ16 × 25 mm can delivers 22 µF in a space-efficient through-hole footprint for legacy or repair-focused assemblies.
• Predictable Electrical Behavior: Specified tanδ and leakage current figures at 20°C, 120 Hz enable easier margining and thermal design decisions.
• RoHS Compliance: Conforms to RoHS requirements where restricted substance compliance is required.

Why Choose UCA2W220MHD?

UCA2W220MHD is positioned for designers maintaining or repairing higher-voltage power electronics and lighting ballast systems where a compact, high-voltage aluminum electrolytic capacitor with proven ripple capability and a long rated life is required. Its 450 V rating, combined with specified ripple currents and a 12,000-hour endurance at 105°C, makes it appropriate for continuous-duty industrial power circuits.

Because this part is listed as End Of Life, it is especially relevant for sustaining legacy designs or planned replacements where form, fit, and electrical characteristics must match existing assemblies. Verify availability and suitability for new designs before specifying.
