UCY2V220MHD3

The UCY2V220MHD3 from Nichicon is a radial-lead, miniature aluminum electrolytic capacitor in the UCY series engineered for high ripple current and long service life. It provides 22 µF capacitance at a 350 V rating in a compact φ12.5 × 20 mm can with 5.0 mm lead spacing.

Designed for power electronics and industrial/automotive applications, this AEC-Q200 qualified, RoHS-compliant component delivers high ripple handling, controlled loss (tanδ), and a demonstrated 10,000 hour endurance at 105°C for reliable operation in demanding environments.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance rated at 350 V for high-voltage filtering and energy storage.
• Tolerance & Loss — Capacitance tolerance of ±20% (−20% to +20%) with tanδ (DF) max 0.24 measured at 20°C, 120 Hz, for predictable impedance and dissipation characteristics.
• High Ripple Current Capability — Low-frequency ripple current 325 mA at 120 Hz and high-frequency ripple current 650 mA at 100 kHz to support power-supply smoothing and switching applications.
• Leakage Current — Specified leakage current of 408 µA for minimized standby loss and predictable leakage behavior.
• Long Endurance — Rated for 10,000 hours life at 105°C under rated voltage and ripple conditions, supporting extended field life in continuous-duty systems.
• Robust Operating Range — Operating temperature range −40°C to +105°C suitable for a wide range of thermal environments.
• Compact Radial Package — φ12.5 × 20 mm can, radial lead mounting with 5.0 mm lead spacing (±0.5 mm) for straightforward PCB placement and through-hole assembly.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant for use in regulated applications and supply chains.

Typical Applications

• Power Supplies — Filtering and smoothing in high-voltage power supplies where 350 V rating and high ripple capability are required.
• Ballasts and Lighting Electronics — Energy storage and ripple attenuation for ballast circuits as indicated in the UCY series guidance.
• Automotive Power Electronics — DC-link and smoothing tasks in automotive power systems, supported by the product's AEC-Q200 qualification and high-temperature endurance.

Unique Advantages

• High ripple tolerance: 650 mA at 100 kHz and 325 mA at 120 Hz enable effective handling of both high-frequency switching and low-frequency ripple currents.
• Proven long life: 10,000 hours at 105°C provides predictable longevity for continuous-duty applications.
• Automotive-capable qualification: AEC-Q200 qualification supports use in automotive-related electronic systems requiring component-level robustness.
• Compact, serviceable form factor: φ12.5 × 20 mm radial can and 5.0 mm lead spacing simplify PCB layout and through-hole assembly while conserving board area.
• Controlled electrical characteristics: Specified tanδ (0.24 at 20°C/120 Hz) and defined leakage current (408 µA) aid designers in impedance and power-loss budgeting.
• Compliance-ready: RoHS compliance supports deployment in regulated manufacturing environments.
