UCA2V220MHD

The UCA2V220MHD is a miniature, radial-lead aluminum electrolytic capacitor offering 22 µF capacitance at a 350 V rated voltage. Designed for high-ripple, long-life service, it targets power supply and ballast applications where compact, high-voltage filtering is required.

Key attributes include a 12000-hour life at +105°C, a wide operating temperature range of −25°C to +105°C, and a compact φ12.5×20 mm can with 5 mm lead spacing—providing a balance of voltage capability, ripple performance, and small footprint.

Key Features

• Rated Performance — 22 µF capacitance at 350 V with ±20% tolerance (120 Hz, 20°C), offering consistent high-voltage energy storage.
• High Ripple Current Handling — Rated ripple current 350 mA (100 kHz) and 175 mA (120 Hz), suitable for demanding AC ripple conditions in power circuits.
• Long Life at Elevated Temperature — Endurance specified for 12000 hours at +105°C under rated DC bias plus rated ripple current.
• Low Loss and Leakage — Tangent of loss angle (tan δ) 0.20 (at 120 Hz, 20°C for 350 V) and measured leakage current of 408 µA after 1 minute at rated voltage (20°C).
• Compact Radial Can — Case size φ12.5×20 mm with 5 mm lead spacing; polarized radial-lead mounting for through-hole assemblies.
• Environmentally Compliant Packaging — RoHS compliant; supplied in Bulk (No Terminal Forming) / Bag Packing for high-volume assembly or manual handling.
• Product Status — This product is scheduled to be discontinued and is not recommended for new designs.

Typical Applications

• Power Supplies — Bulk and decoupling capacitor for high-voltage sections where 350 V ratings and high ripple capability are required.
• Ballasts — Suited for ballast circuits specified in the product datasheet where long life and steady ripple handling matter.
• General-purpose High-voltage Circuits — Polarized, radial can design for general-purpose DC filtering and energy storage in high-voltage assemblies.

Unique Advantages

• High ripple endurance: 350 mA at 100 kHz and 175 mA at 120 Hz provide reliable performance under continuous AC stress.
• Extended operating life: 12000 hours at +105°C supports long maintenance intervals in temperature-challenging environments.
• Compact footprint: φ12.5×20 mm can and 5 mm lead spacing enable space-efficient layout for through-hole designs.
• Predictable electrical behavior: Specified tan δ (0.20) and measured leakage current (408 µA) allow engineers to model loss and standby current precisely.
• Regulatory compliance: RoHS compliance supports environmental requirements for end products.

Why Choose UCA2V220MHD?

The UCA2V220MHD positions itself as a compact, high-voltage aluminum electrolytic solution that combines measurable ripple capability, controlled dissipation, and long life at elevated temperature. Its radial can and 5 mm lead spacing make it straightforward to integrate into through-hole power assemblies where space is limited but voltage and ripple performance remain critical.

Engineers specifying for power supplies, ballasts, or general-purpose high-voltage filtering will find clear, verifiable electrical and mechanical data—capacitance, voltage, ripple, leakage, and lifetime—allowing confident lifetime and thermal budgeting. Note: this product is scheduled to be discontinued and is not recommended for new designs.
