UCY2W680MHD

The UCY2W680MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UCY series. It is a radial-lead, polarized electrolytic designed for high-voltage, high-ripple applications where long load life and robust thermal performance are required.

Typical use cases include power-supply filtering and ballast circuits, with explicit suitability for automotive applications supported by AEC-Q200 rating. Key value propositions are its high ripple-current capability, extended endurance at elevated temperature, and compact radial-can package.

Key Features

• Capacitance & tolerance — 68 µF nominal capacitance with a tolerance of -20% to +20% at 120 Hz, 20°C.
• High voltage rating — Rated for 450 V DC operation to support high-voltage power rails.
• Low dissipation factor — tanδ (DF) of 0.24 measured at 20°C, 120 Hz, indicating controlled ESR behavior for power applications.
• Ripple current capability — Low-frequency ripple current 660 mA (120 Hz) and high-frequency ripple current 1.32 A (100 kHz) for demanding smoothing and decoupling tasks.
• Leakage current — Specified leakage current of 1324 µA, measured per product conditions.
• Extended endurance — Life/endurance rated at 12,000 hours at 105°C under specified conditions.
• Operating temperature range — −40°C to +105°C for broad thermal use.
• Compact radial can — Physical size φ16 × 35.5L mm (3.55 × 1.6 cm), radial lead mounting with 7.5 mm lead spacing (±0.5 mm).
• Automotive-grade qualification — AEC-Q200 rated, and RoHS compliant.
• Packaging and availability — Offered in bulk (no terminal forming) or bag packing; current status: mass production.

Typical Applications

• Power supplies — Smoothing and bulk energy storage on high-voltage DC rails where high ripple current and long life are required.
• Ballast circuits — Filtering and ripple attenuation in ballast and lighting driver topologies that operate at elevated voltages.
• Automotive power electronics — Energy storage and decoupling in automotive systems where AEC-Q200 qualification and extended high-temperature endurance are needed.

Unique Advantages

• High ripple-current handling: Rated ripple currents of 660 mA (120 Hz) and 1.32 A (100 kHz) enable effective smoothing under both low- and high-frequency loading conditions.
• Long-term reliability at elevated temperature: 12,000 hours life at 105°C provides predictable endurance for designs that operate continuously in high-heat environments.
• High-voltage capability: 450 V rating supports high-voltage power rails without additional stacking or derating.
• Automotive-grade qualification: AEC-Q200 rating aligns the component with automotive development needs for qualified passive components.
• Compact radial form factor: φ16 × 35.5L can with 7.5 mm lead spacing delivers a small footprint for through-hole mounting while preserving capacitance and ripple performance.
• Regulatory compliance: RoHS compliant for use in regulated product designs.
