UCY2G470MHD6

The UCY2G470MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a radial-lead, polarized capacitor rated at 47 µF and 400 V, designed for demanding power applications that require high ripple handling and extended operating life.

Targeted use cases include power supply and ballast applications and automotive electronics, where long endurance, high-voltage capability and compact radial-can packaging are required. The part combines high ripple current performance, AEC-Q200 qualification, and a long rated life at elevated temperature.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 400 V rated voltage and tolerance of −20% to +20%.
• High Ripple Current — Rated ripple current of 510 mA at 120 Hz (low frequency) and 1.02 A at 100 kHz (high frequency), enabling robust filtering in power stages.
• Long Endurance — Load-life rated for 12,000 hours at 105°C (with applicable conditions per series specifications), supporting long-term stability under continuous stress.
• AEC-Q200 Qualified — Series-level AEC-Q200 qualification and RoHS compliance suitable for automotive-grade designs.
• Temperature Range — Operates from −40°C to +105°C to handle wide ambient conditions.
• Low Loss Characteristic — Tangent of loss angle (tan δ) up to 0.24 measured at 20°C, 120 Hz for the 400 V rating.
• Leakage Current — Specified leakage current of 852 µA, measured per product conditions.
• Compact Radial-Lead Package — φ12.5 × 30.5 mm (L × D: 3.05 × 1.25 cm) radial can with 5 mm lead spacing; available in bulk or bag packing (no terminal forming).
• Frequency Coefficient of Ripple Current — Coefficients: 0.80 at 50 Hz, 1.00 at 120 Hz, 1.60 at 1 kHz, 1.80 at 10 kHz, and 2.00 at 100 kHz or more, enabling performance scaling across switching frequencies.

Typical Applications

• Automotive Electronics — Suitable for automotive power systems requiring AEC-Q200-qualified components and high-voltage filtering.
• Power Supplies — Used in power supply filtering and smoothing where high ripple current capability and 400 V rating are required.
• Ballasts and Lighting — Suited for ballast applications as specified by the UCY series, providing reliable performance under continuous AC/DC stress.

Unique Advantages

• High ripple capability: Dual ripple current ratings (low and high frequency) let designers address both mains-frequency and switching-frequency stress without overspecifying parts.
• Extended load life at 105°C: 12,000-hour endurance supports long-term reliability in thermally demanding installations.
• Automotive-ready qualification: AEC-Q200 series qualification and RoHS compliance simplify selection for automotive and related sectors.
• Compact radial form factor: φ12.5 mm can and 5 mm lead spacing deliver a small footprint for space-constrained power modules.
• Predictable frequency behavior: Published frequency coefficients allow straightforward ripple-current derating across switching frequencies.
• Clear electrical specs: Specified tan δ, leakage current, and tolerance provide measurable parameters for design validation and reliability analysis.
