UCY2D680MHD3

The UCY2D680MHD3 is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for applications that require sustained ripple handling and long operating life. It belongs to Nichicon’s UCY series and is optimized for power-supply and ballast applications, with explicit suitability for automotive use.

With a 68 µF capacitance at 200 V, a wide operating temperature range and AEC-Q200 rating, this part delivers durable performance where elevated ripple currents and extended endurance are required.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance at 200 V for energy storage and decoupling in power circuits.
• High ripple capability — Low-frequency ripple current 650 mA (120 Hz) and high-frequency ripple current 1.3 A (100 kHz) to handle demanding AC components on DC rails.
• Long endurance — Rated for 10,000 hours at 105°C, providing extended operational life in high-temperature environments.
• Wide temperature range — Operates from −40°C to +105°C to cover harsh environmental conditions.
• Electrical performance — Dissipation factor (tan δ) 0.20 (measured at 20°C, 120 Hz) and leakage current of 644 µA, enabling predictable behavior in filter and smoothing applications.
• Package & mounting — Radial lead configuration in a φ12.5 × 20 mm can with 5 mm lead spacing (±0.5 mm), suitable for through-hole PCB mounting.
• Compliance — AEC-Q200 rated and RoHS compliant for regulated markets and reliability-focused applications.
• Packaging options — Available in bulk (no terminal forming) or bag packing for flexible handling and assembly workflows.

Typical Applications

• Automotive electronics — Use in vehicle power systems where AEC-Q200 qualification and extended high-temperature life are required.
• Power supplies — Bulk smoothing and ripple attenuation in power supply rails and related power-conditioning circuits.
• Ballasts — Suited for ballast application environments that demand stable capacitance and high ripple tolerance.

Unique Advantages

• Robust ripple handling: Specified ripple currents at both low and high frequencies (650 mA at 120 Hz; 1.3 A at 100 kHz) reduce stress on upstream circuitry and improve overall system stability.
• Extended high-temperature life: 10,000 hours at 105°C supports designs where long-term endurance under thermal stress is critical.
• Automotive-grade reliability: AEC-Q200 rating provides confidence for use in regulated and reliability-critical automotive subsystems.
• Compact radial can: φ12.5 × 20 mm package with 5 mm lead spacing delivers a space-efficient through-hole solution for legacy and serviceable boards.
• Predictable electrical characteristics: Defined tan δ and leakage current figures allow straightforward integration into filter and decoupling networks.
• Regulatory compatibility: RoHS compliance simplifies environmental and regulatory planning for end products.
