UCY2C471MHD

The UCY2C471MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series designed for miniature, high-ripple-current applications. It delivers 470 µF capacitance at a 160 V rating with polarized radial can packaging optimized for power-supply and ballast use.

Targeted at demanding environments, this part combines a compact φ18 × 35.5 mm can, high ripple-current capability, long endurance at elevated temperature, and AEC-Q200 qualification for automotive applications.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 160 V and tolerance of ±20% (120 Hz, 20°C).
• High Ripple Current — Rated low-frequency ripple current 1.92 A at 120 Hz and high-frequency ripple current 3.84 A at 100 kHz to support power filtering under heavy AC/rectified loads.
• Long Endurance — 12,000 hours life at 105°C under rated DC bias plus ripple current, enabling extended operation in elevated-temperature environments.
• Temperature Range — Rated for −40°C to +105°C operation to cover wide thermal conditions.
• Electrical Loss Characteristics — tan δ (DF) ≤ 0.2 measured at 20°C, 120 Hz, supporting predictable dissipation and AC performance.
• Leakage Current — Specified leakage current 3,108 µA (formula-based limit: 0.04CV + 100 µA), for predictable end-of-line performance.
• Package & Mounting — Radial lead (can) package, size φ18 × 35.5 mm, lead spacing 7.5 mm (±0.5 mm), supplied in bulk or bag packing for flexible assembly workflows.
• Automotive Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, indicating suitability for automotive system designs and regulatory conformance.

Typical Applications

• Power supplies — Bulk energy storage and output smoothing in power-supply rails where high ripple current handling and 160 V rating are required.
• Ballast circuits — Filtering and energy buffering in ballast and lamp-drive applications that demand high ripple endurance and long operating life.
• Automotive electronics — Power filtering and decoupling in automotive systems, leveraging AEC-Q200 qualification and 105°C endurance for robust in-vehicle operation.

Unique Advantages

• High ripple tolerance: Specified 1.92 A (120 Hz) and 3.84 A (100 kHz) ripple currents reduce thermal stress and extend operational stability in AC-loaded circuits.
• Extended high-temperature life: 12,000-hour endurance at 105°C conservatively supports long service intervals in heat-prone installations.
• Clear electrical specifications: Defined tan δ (0.20 at 120 Hz, 20°C) and leakage current limits enable predictable design margins for loss and leakage budgeting.
• Automotive-ready: AEC-Q200 qualification and RoHS compliance provide traceable suitability for automotive electronics and regulated environments.
• Compact radial form factor: φ18 × 35.5 mm can with 7.5 mm lead spacing offers a space-efficient solution for through-hole power designs and retrofit replacements.
• Production availability: Mass-production status with bulk/bag packing supports volume procurement and assembly workflows.
