UCD2A221MNQ1MS

The UCD2A221MNQ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount applications. It provides 220 µF capacitance at a 100 V rating in a compact SMD can package intended for high-density PCBs.

Engineered for demanding temperature and endurance requirements, this part is suitable for designs that require stable capacitance, controlled dissipation factor, and measurable ripple handling across low and high frequencies. It is RoHS compliant and AEC-Q200 qualified for automotive applications.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Impedance Performance — Low dissipation factor (tanδ = 0.07 measured at 20°C, 120 Hz, 100 V) for efficient AC performance and reduced losses.
• Ripple Current Capability — Specified low-frequency ripple current of 458.5 mA at 120 Hz and high-frequency ripple current of 917 mA at 10 kHz to support dynamic supply filtering.
• Leakage Current — Leakage current specified at 220 µA, supporting predictable bias behavior after voltage application.
• Endurance & Temperature Range — Rated for operation from −55°C to +105°C with a lifetime/endurance specification of 5000 hours at 105°C.
• Surface-Mount Package — Chip-type radial can SMD (φ18 × 16.5 mm) supplied in embossed carrier taping for automated placement.
• Industry Compliance — RoHS compliant and AEC-Q200 qualified, suitable for regulated electronic applications.

Typical Applications

• Automotive Electronics — Designed for automotive systems where high voltage rating, wide temperature range (−55°C to +105°C) and AEC-Q200 qualification are required for reliable decoupling and energy storage.

Unique Advantages

• High Voltage Handling: 100 V rating enables use in higher-voltage sections of power systems without series stacking.
• Controlled Losses: Low tanδ (0.07 at 120 Hz, 20°C) reduces dissipation and helps maintain stability under AC conditions.
• Broad Ripple Support: Defined ripple current values at both low and high frequencies let designers evaluate thermal and AC stress reliably.
• Wide Operating Temperature: −55°C to +105°C range supports applications across harsh thermal environments.
• Long Endurance: 5000 hours at 105°C provides predictable life performance for long-term deployments.
• SMD-Friendly Packaging: Embossed carrier taping and compact φ18 × 16.5 mm can format simplify automated assembly on dense PCBs.
