UCY2D331MHD

The UCY2D331MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-can package from Nichicon’s UCY series. It provides 330 µF capacitance at a 200 V rating with polarized radial leads and is designed for applications requiring high ripple current handling and long operational life.

Engineered for power applications including power supplies and ballasts, this component combines elevated ripple-current capability, extended endurance at elevated temperature, and AEC-Q200 qualification to address demanding environments such as automotive power electronics.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 200 V rated voltage and capacitance tolerance of -20% to +20%.
• High Ripple Current: Low-frequency ripple current of 1.595 A at 120 Hz and high-frequency ripple current of 3.19 A at 100 kHz, supporting high-stress power filtering and smoothing.
• Long Life & Endurance: Rated for 12,000 hours at 105°C under DC bias plus rated ripple current, providing extended service life in elevated-temperature applications.
• Thermal & Electrical Stability: Operating temperature range of -40°C to +105°C with a dissipation factor (tan δ) of 0.20 measured at 20°C, 120 Hz for stable performance across temperature and frequency.
• Radial Lead Package: φ16 × 40 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and easy PCB placement; available in bulk or bag packing (no terminal forming).
• Reliability & Compliance: AEC-Q200 qualified and RoHS compliant, suitable for regulated and quality-driven product designs.
• Leakage Current: Specified leakage current of 2740 µA, measurable after application of rated voltage per the product specifications.

Typical Applications

• Automotive Power Electronics: Energy smoothing and filtering in automotive power modules where AEC-Q200 qualification and wide temperature operation are required.
• Power Supplies: Bulk and smoothing capacitor for DC power supplies and converters that require high ripple-current capacity and long endurance at elevated temperatures.
• Ballasts and Lighting Power Units: Filtering and ripple suppression in ballast circuits and lighting power modules where reliable high-frequency performance is needed.

Unique Advantages

• High ripple-current capability: Enables smaller capacitor count or reduced cooling demands by handling up to 1.595 A at 120 Hz and 3.19 A at 100 kHz.
• Long operational life at high temperature: 12,000-hour endurance at 105°C helps ensure predictable aging and service intervals in hot environments.
• AEC-Q200 qualification: Provides an industry-recognized reliability baseline for designs targeting automotive and similarly demanding markets.
• Compact radial-can form factor: φ16 × 40 mm size with standardized 7.5 mm lead spacing simplifies through-hole assembly and retrofit into existing layouts.
• RoHS compliant: Meets environmental regulatory requirements for lead-free applications.
• Frequency-aware ripple scaling: Datasheet frequency coefficients (up to 2.0 at 100 kHz) allow designers to account for increased allowable ripple at higher frequencies.
