UCY2D471MHD6

The UCY2D471MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a radial-lead, polarized capacitor specified at 470 μF and 200 V, designed for demanding power applications that require sustained performance at elevated temperature and ripple loading.

Key value propositions include a long rated life of 12,000 hours at 105°C, AEC-Q200 qualification, and robust ripple-current capability across low and high frequencies—making it suitable for power supplies, ballast circuits, and automotive power electronics where long-term stability and reliability are required.

Key Features

• Capacitance & Voltage — 470 μF rated capacitance with a rated voltage of 200 V and capacitance tolerance of -20% to +20% (measured at 20°C, 120 Hz).
• High Ripple Current — Low-frequency ripple current rated at 1.9 A (120 Hz) and high-frequency ripple current rated at 3.8 A (100 kHz), supporting high-demand power filtering and decoupling.
• Long Life Endurance — Rated for 12,000 hours at 105°C under DC bias plus rated ripple current, with specified limits for capacitance change, dissipation factor, and leakage after endurance.
• Temperature Range — Operating range from -40°C to +105°C for wide ambient tolerance in harsh environments.
• Low Loss Characteristics — Specified tangent of loss angle (tanδ) of 0.20 at 20°C, 120 Hz for stable performance in AC ripple conditions.
• Package & Leaded Mounting — Radial lead can package (φ18 × 46 mm) with 7.5 mm lead spacing and bulk/bag packing options for production assembly flexibility.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant, supporting regulated and reliability-driven applications.

Typical Applications

• Automotive Power Electronics — Bulk smoothing and ripple handling in power modules, ECUs, and automotive power systems where AEC-Q200 qualification and long life are required.
• Power Supplies — Energy storage and output filtering in DC–DC converters and high-voltage power supplies that need sustained ripple-current capability and thermal endurance.
• Ballasts and Lighting Drives — Filtering and energy buffering in ballast circuits, leveraging the UCY series’ suitability for ballast applications.

Unique Advantages

• Demonstrated High-Ripple Capability — Specified ripple-current ratings of 1.9 A (120 Hz) and 3.8 A (100 kHz) allow designers to size capacitors confidently for both low- and high-frequency ripple environments.
• Extended High-Temperature Lifetime — 12,000 hours at 105°C provides predictable end-of-life behavior for long-duration thermal stress scenarios.
• Automotive-Grade Reliability — AEC-Q200 qualification supports usage in automotive and other reliability-sensitive systems.
• Compact Radial Can — φ18 × 46 mm radial can package with 7.5 mm lead spacing offers a compact, through-hole form factor for robust mechanical mounting and easy PCB integration.
• Measured Loss & Leakage Specs — tanδ of 0.20 (120 Hz, 20°C) and a specified leakage current (3860 μA) support predictable electrical behavior in design margins and thermal planning.
• RoHS Compliant — Meets RoHS requirements for use in regulated global markets.
