UCA2D680MHD6

The UCA2D680MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCA series. It delivers 68 µF capacitance at a 200 V rating in a compact can package, designed for applications that require elevated ripple-handling capability and long operational life.

Engineered for power supply and ballast applications, the device offers a 12000-hour load life at 105°C and is RoHS compliant. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current — Rated ripple current of 485 mA at 120 Hz and 970 mA at 100 kHz for handling AC components in high-stress circuits.
• Long Life Endurance — Load life specified at 12000 hours at 105°C (endurance confirmed after D.C. bias plus rated ripple current).
• Low Loss Characteristics — Tangent of loss angle (tan δ) of 0.15 measured at 120 Hz and 20°C, supporting predictable dissipation behavior.
• Temperature Range — Rated for operation from −25°C to +105°C.
• Compact Radial Package — Radial, can-style package with 7.5 mm lead spacing, dimensions L: 2 cm × D: 1.6 cm and a maximum seated height of 2 cm.
• Polarity — Polarized construction suitable for standard electrolytic capacitor usage.
• Environmental Compliance — RoHS compliant in accordance with applicable directives.

Typical Applications

• Power Supplies — Suited for power supply applications that demand elevated ripple-current capability and long operational life.
• Ballasts — Designed for ballast applications where stable capacitance and endurance at elevated temperatures are required.
• General Purpose Electronics — Applicable where a compact, polarized electrolytic capacitor with predictable loss and long-life characteristics is needed.

Unique Advantages

• High ripple endurance: Specified ripple current values (485 mA @ 120 Hz, 970 mA @ 100 kHz) enable reliable handling of AC stress in demanding circuits.
• Extended operational life: 12000-hour rating at 105°C provides durability in high-temperature environments.
• Compact footprint: Small radial can (L: 2 cm × D: 1.6 cm) with 7.5 mm lead spacing helps preserve PCB area in space-constrained designs.
• Stable electrical behavior: Low loss tangent (tan δ = 0.15 at 120 Hz, 20°C) and defined tolerance support predictable circuit performance.
• Regulatory compliance: RoHS conformity simplifies design for lead-free regulatory requirements.
