UUG2W220MNQ1MS

The UUG2W220MNQ1MS is a Nichicon UUG-series aluminum electrolytic chip capacitor in a surface-mount radial can package. It provides 22 µF capacitance at a 450 V rating in a compact chip form factor designed for high-voltage, polarized applications.

Engineered for automotive and industrial power electronics, this part combines a wide operating temperature range and endurance specification with measurable ripple-handling capability to support high-voltage DC filtering and energy smoothing tasks.

Key Features

• Electrical Performance — 22 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (120 Hz, 20°C) for polarized high-voltage DC applications.
• Reliability & Endurance — Specified for 2000 hours at 85°C; endurance criteria (restored to 20°C) include capacitance change within ±20% and tan δ ≤ 200% of initial value per the series endurance definition.
• Automotive-Grade Qualification — AEC-Q200 rating and explicit application listing for automotive use, supporting designs that require component-level automotive reliability.
• Temperature Range — Rated for operation from −40°C to +85°C, matching the series category temperature range for chip-type aluminum electrolytics.
• Package & Mounting — Surface-mount, radial can (can - SMD) chip type with package dimensions L: 2.15 × D: 1.6 cm and a recommended land size L: 1.63 × W: 1.63 cm for PCB footprint design.
• Ripple Current Capability — Rated ripple current of 275 mA at 120 Hz and 440 mA at 10 kHz, suitable for AC ripple filtering and decoupling at common frequencies.

Typical Applications

• Automotive Power Rails — High-voltage DC filtering and smoothing on in-vehicle power systems where AEC-Q200 qualification and elevated voltage rating are required.
• Power Conversion Modules — Bulk decoupling and energy storage in DC–DC converters and power-supply front-ends that operate at high DC bus voltages.
• High-Voltage Filtering — Noise suppression and ripple reduction on high-voltage supply lines using the part’s 450 V rating and defined ripple current capability.

Unique Advantages

• High Voltage in an SMD Chip Can: 450 V rating in a compact chip-style radial can enables high-voltage designs without through-hole components.
• AEC-Q200 Qualification: Provides a level of component qualification suitable for automotive applications, helping address reliability requirements.
• Defined Endurance: 2000 hours at 85°C with specified post-test limits gives designers quantifiable lifetime performance for thermal and electrical stress planning.
• Measurable Ripple Handling: Specified ripple currents at 120 Hz and 10 kHz allow designers to size capacitors based on expected ripple conditions and frequency-dependent demands.
• PCB Footprint Provided: Published surface-mount land size (1.63 × 1.63 cm) and package dimensions simplify layout and mechanical integration into compact assemblies.
