UCS2D680MHD

The UCS2D680MHD is a miniature, high-reliability aluminum electrolytic capacitor in the Nichicon UCS series, supplied in a radial-lead can. It delivers 68 µF capacitance at a 200 V rating and is designed for general-purpose power electronics where sustained ripple handling and long operational life are required.

Targeted applications include power supplies and ballast circuits; the part combines elevated ripple-current capability with long-term endurance at elevated temperature for dependable performance in demanding environments.

Key Features

• Capacitance & Voltage: 68 µF nominal capacitance rated for 200 V DC.
• High Ripple Current: Low-frequency ripple current 650 mA at 120 Hz and high-frequency ripple current 1.3 A at 100 kHz, supporting heavy AC ripple conditions.
• Long Endurance: Rated life of 10000 hours at 105°C under DC bias plus rated ripple current, per UCS series endurance specifications.
• Temperature Range: Operating temperature range from −40°C to 105°C for a broad range of environments.
• Electrical Loss & Leakage: Dissipation factor (tanδ) 0.20 measured at 20°C, 120 Hz, and specified leakage current of 644 µA.
• Tolerance & Polarization: Capacitance tolerance −20% to +20%; polarized electrolytic construction.
• Package & Mounting: Radial lead can, physical size φ12.5 × 20 mm with 5 mm lead spacing (±0.5 mm), supplied Bulk (no terminal forming) or Bag packing.
• Regulatory: RoHS compliant.

Typical Applications

• Power Supplies: Bulk or filtering capacitor for DC power supplies, offering high ripple-current capability and long life at elevated temperature.
• Ballasts: Suitable for ballast applications where sustained ripple and thermal endurance are required.
• General-Purpose Power Electronics: Use in general-purpose circuits that need a compact, polarized aluminum electrolytic with verified endurance and ripple performance.

Unique Advantages

• High ripple-handling capability: Rated ripple currents of 650 mA (120 Hz) and 1.3 A (100 kHz) reduce stress on upstream components and improve system stability under AC load.
• Extended high-temperature life: 10000-hour endurance at 105°C supports sustained operation in thermally demanding designs.
• Compact radial-lead form factor: φ12.5 × 20 mm can and 5 mm lead spacing enable space-efficient board layouts while retaining through-hole robustness.
• Predictable electrical characteristics: Specified tanδ (0.20 at 20°C/120 Hz) and defined leakage current (644 µA) simplify margining and reliability calculations.
• Production-ready supply: Part is in mass production and available in standard bulk or bag packing for streamlined procurement.
• RoHS compliant: Meets RoHS requirements for restricted substances.
