UCD2A221MNJ1MS

The UCD2A221MNJ1MS is a surface-mount, chip-type aluminum electrolytic capacitor designed for low-impedance applications. It delivers 220 µF nominal capacitance at a 100 V rated voltage in a compact radial can SMD package optimized for automated assembly.

Targeted at automotive and high-density power electronics, this AEC-Q200–rated capacitor offers high-temperature endurance and measurable ripple-handling capability for demanding board-level power filtering and decoupling tasks.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with ±20% tolerance and a 100 V rated voltage for use on higher-voltage rails.
• Low impedance / Dissipation factor: tanδ of 0.07 (measured at 20°C, 120 Hz), supporting low-loss performance in AC and ripple environments.
• 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 for effective smoothing of varying frequency ripple.
• Leakage current: Rated leakage current of 220 µA to aid predictable bias behavior in DC circuits.
• High-temperature endurance: Life rating of 5000 hours at 105°C, with operating temperature range from −55°C to +105°C for prolonged reliability.
• Surface-mount package & assembly: Chip-type radial can SMD (φ18 × 16.5L, seated height 1.65 cm) supplied in embossed carrier taping for automatic placement; recommended land size L: 1.83 × W: 1.83 cm.
• Standards and compliance: AEC-Q200 qualified and RoHS compliant as specified for automotive and regulated applications.

Typical Applications

• Automotive power electronics: Bulk smoothing and decoupling on high-voltage rails and control modules where AEC-Q200 qualification and elevated temperature endurance are required.
• DC–DC converters and power modules: Output filtering and ripple attenuation on converters operating up to 100 V.
• High-density surface-mount assemblies: Automatic tape-fed placement on compact PCBs that require SMD aluminum capacitor performance in limited board area.

Unique Advantages

• High-voltage capability: 100 V rating enables use on higher-voltage rails without multiple-device stacking.
• Measurable low-loss performance: Low tanδ (0.07 at 120 Hz) supports efficient filtering and preserves signal integrity under AC conditions.
• Engineered for ripple handling: Specified low- and high-frequency ripple currents (458.5 mA at 120 Hz, 917 mA at 10 kHz) give designers clear limits for thermal and reliability planning.
• Automotive-grade reliability: AEC-Q200 qualification plus 5000-hour endurance at 105°C align the part with demanding lifecycle and temperature requirements.
• Assembly-ready packaging: Embossed carrier taping and SMD can format facilitate automated placement and high-density board designs.
• Regulatory compliance: RoHS compliance supports use in regulated manufacturing environments.
