UCY2W220MHD

The UCY2W220MHD is a Nichicon UCY series radial-lead aluminum electrolytic capacitor rated at 22 µF and 450 V. It combines a compact radial can package (φ12.5 × 25 mm) with high-voltage capability for use in demanding power applications.

Designed for high ripple environments and extended operation, this part delivers specified performance across −40 °C to 105 °C and is AEC‑Q200 qualified and RoHS compliant, making it suitable for automotive and industrial power-electronics designs.

Key Features

• Capacitance & Tolerance — 22 µF with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated Voltage — 450 V DC for high-voltage power stages and filtering.
• Loss Tangent — tan δ = 0.24 (max.) at 20 °C, 120 Hz, supporting predictable dissipation characteristics.
• Ripple Current Capability — 300 mA at 120 Hz (low frequency) and 600 mA at 100 kHz (high frequency) for robust AC ripple handling.
• Leakage Current — Specified leakage current of 496 µA.
• Long Life / Endurance — Rated life of 12,000 hours at 105 °C with DC bias plus rated ripple current; endurance criteria include capacitance within ±20% and leakage at or below initial specified value after test.
• Operating Temperature — −40 °C to 105 °C for wide-temperature deployments.
• Package & Mounting — Radial lead can, φ12.5 × 25 mm size with 5.0 mm lead spacing (±0.5 mm); available in bulk or bag packing.
• Quality & Compliance — AEC‑Q200 qualified and RoHS compliant, supporting regulated and automotive-grade programs.

Typical Applications

• Power supplies — Bulk filtering and smoothing in high-voltage power rails where 450 V rating and high ripple capability are required.
• Ballasts and lighting drivers — Energy-storage and ripple handling in high-voltage lamp and driver circuits.
• Automotive electronics — Use in automotive power modules and control units where AEC‑Q200 qualification and extended life at 105 °C are required.

Unique Advantages

• High-voltage capability — 450 V rating enables use in elevated-voltage power stages without upsizing capacitance or package.
• Elevated ripple tolerance — Specified ripple currents at both low and high frequencies (300 mA at 120 Hz, 600 mA at 100 kHz) reduce thermal stress and extend service life in AC-loaded circuits.
• Long rated lifetime at high temperature — 12,000 hours at 105 °C under rated conditions provides predictable longevity for long-term installations.
• Compact radial package — φ12.5 × 25 mm can with 5 mm lead spacing saves board area while retaining robust electrical performance.
• Automotive-ready qualification — AEC‑Q200 qualification supports use in regulated automotive applications requiring recognized component-level quality.
• RoHS compliant — Meets environmental directive requirements for restricted substances.
