UCY2H470MHD

The UCY2H470MHD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial lead can. It delivers 47 µF capacitance at a 500 V rating with a compact φ16 × 40 mm can and 7.5 mm lead spacing.

Designed for demanding power applications, this UCY series part combines high ripple current capability, long load life at elevated temperature, and industry compliance to provide predictable performance for power supply filtering, ballast circuits and automotive electronic modules.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 500 V rated voltage and ±20% tolerance.
• High Ripple Current — Rated low‑frequency ripple current 440 mA at 120 Hz and high‑frequency ripple current 880 mA at 100 kHz, supporting demanding AC stress on DC link and filter circuits.
• Long Endurance — Specified life of 10000 hours at +105°C under rated conditions, supporting extended operational service in hot environments.
• Thermal Range — Operates from −40 °C to +105 °C, enabling use across broad ambient conditions.
• Electrical Losses — Tangent of loss angle (tan δ) 0.24 measured at 20 °C, 120 Hz, 500 V; leakage current specified at 1040 µA.
• Package & Mounting — Radial lead can with φ16 mm diameter, 40 mm length and 7.5 mm lead spacing (±0.5 mm); available packaged in bulk or bag packing (no terminal forming).
• Reliability & Compliance — AEC‑Q200 rating on record and RoHS compliant, reflecting suitability for regulated and reliability‑focused applications.

Typical Applications

• Power supplies — Filtering and smoothing in high‑voltage power supply rails where high ripple current capability and long life are required.
• Ballast circuits — Energy storage and ripple management for ballast and lamp drive applications as noted in the UCY series guidance.
• Automotive electronic modules — Use in automotive power electronics and control modules that demand AEC‑Q200 qualified components and wide temperature operation.

Unique Advantages

• High voltage handling: 500 V rating enables use in higher‑voltage DC rails and power stages without series stacks.
• Designed for ripple stress: Dual ripple current ratings (440 mA @120 Hz, 880 mA @100 kHz) provide clear guidance for both line‑frequency and high‑frequency filtering scenarios.
• Extended elevated‑temperature life: 10000‑hour endurance at +105 °C supports long service intervals in thermally stressful installations.
• Automotive‑grade qualification: AEC‑Q200 listing supports selection for automotive and similarly demanding applications.
• Compact radial form factor: φ16 × 40 mm can with standard 7.5 mm lead spacing simplifies PCB layout for through‑hole designs while maintaining high energy density.
• Regulatory compliance: RoHS compliant to align with environmental requirements.
