UCY2D471MHD

The UCY2D471MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UCY series, offered in a radial lead can. It provides 470 µF capacitance at a 200 V rating with a compact φ18 × 40 mm package and 7.5 mm lead spacing.

Designed for applications that demand high ripple handling and long operational life, this high-reliability type is suitable for power supply and ballast applications and is AEC‑Q200 qualified and RoHS compliant for use in regulated environments.

Key Features

• Capacitance & Voltage — 470 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C); rated for 200 V DC.
• High Ripple Current — Low-frequency ripple current 1.85 A at 120 Hz and high-frequency ripple current 3.7 A at 100 kHz for robust filtering under AC loading.
• Long Life Endurance — Rated life of 12,000 hours at 105°C under DC bias plus rated ripple current, with specified limits on capacitance change and leakage after the endurance test.
• Low Dissipation Factor — tanδ (DF) 0.20 max measured at 20°C, 120 Hz, supporting efficient operation in ripple environments.
• Leakage Current — Specified leakage current of 3,860 µA (measured per standard conditions).
• Wide Operating Temperature — −40°C to +105°C rating for broad environmental tolerance.
• Compact Radial Can — φ18 × 40 mm size with 7.5 mm lead spacing; available in bulk or bag packing for through-hole assembly workflows.
• AEC‑Q200 Qualified & RoHS Compliant — Meets AEC‑Q200 qualification and RoHS directive for designs requiring those qualifications.
• Frequency Coefficients Provided — Ripple current frequency coefficients available (0.80 @50 Hz, 1.00 @120 Hz, 1.60 @1 kHz, 1.80 @10 kHz, 2.00 @100 kHz+) to scale rated ripple by operating frequency.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing on 200 V rails where high ripple tolerance and long life improve supply stability.
• Ballasts — Suited for ballast circuits as noted in the product series datasheet, offering high ripple handling and extended endurance at elevated temperatures.
• Automotive Electronics — AEC‑Q200 qualification supports use in automotive electronic modules that require a 200 V-rated, high-reliability electrolytic capacitor.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low and high frequencies reduce thermal stress and extend service life in ripple-heavy circuits.
• Predictable long-term performance: 12,000-hour endurance at 105°C provides designers with a defined lifecycle for thermal and electrical stress planning.
• Standards compliance: AEC‑Q200 qualification and RoHS compliance address reliability and regulatory requirements for a range of applications.
• Compact, through-hole form factor: The φ18 × 40 mm radial can balances high capacitance with a small footprint for conventional PCB assembly.
• Design transparency: Specified tanδ, leakage, ripple currents, and frequency coefficients enable engineers to model performance across temperature and frequency domains.
