UCY2G680MHD

The UCY2G680MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series, specified for high ripple current and long-life applications. It provides 68 µF capacitance at a 400 V rating in a compact φ12.5 × 40 mm can with 5 mm lead spacing.

Designed for power electronics and automotive modules, this high-reliability capacitor delivers controlled dissipation factor and endurance at elevated temperature, making it suitable for power supply filtering and ballast applications where sustained ripple handling and longevity are required.

Key Features

• Capacitance & Voltage: 68 µF nominal capacitance with a 400 V rated voltage, suitable for high-voltage DC filtering and energy-storage roles.
• Miniature radial can package: φ12.5 × 40 mm can with 5 mm lead spacing and radial lead mounting for through-hole assembly flexibility.
• High ripple current capability: Low-frequency ripple current 720 mA at 120 Hz and high-frequency ripple current 1.44 A at 100 kHz, enabling effective smoothing under dynamic load.
• Long life at elevated temperature: Endurance rated for 12,000 hours at 105 °C under specified load conditions, supporting extended service life in demanding environments.
• Electrical loss performance: tan δ = 0.24 measured at 20 °C, 120 Hz (400 V), indicating controlled dissipation for stable operation.
• Polarized aluminum electrolytic: Polarized device with capacitance tolerance ±20% and specified leakage current value.
• Compliance & packaging: AEC‑Q200 rated and RoHS compliant; available in bulk (no terminal forming) or bag packing with mass production status.

Typical Applications

• Power supplies: Bulk and output filtering for high-voltage power supplies where sustained ripple current and high voltage rating are required.
• Ballasts and lamp drivers: Energy storage and smoothing in ballast circuits, leveraging the series’ suitability for ballast applications.
• Automotive electronic modules: Use in automotive power electronics and control modules where AEC‑Q200 qualification and extended temperature endurance are needed.

Unique Advantages

• High ripple tolerance: Rated ripple currents (720 mA @120 Hz, 1.44 A @100 kHz) reduce heating and extend service life in dynamic power systems.
• Extended high-temperature endurance: 12,000-hour life at 105 °C supports long-term reliability in thermally demanding environments.
• Compact footprint for high voltage: 68 µF at 400 V in a φ12.5 × 40 mm package conserves board area compared with larger can sizes.
• Automotive-capable qualification: AEC‑Q200 rating aligns the part with automotive design requirements where that qualification is required.
• Through-hole simplicity: Radial lead form and standard 5 mm lead spacing simplify prototyping and through-hole assembly processes.
• Regulatory compliance: RoHS compliant construction supports use in regulated manufacturing environments.
