UCP2G680MHD

The UCP2G680MHD is a radial-lead aluminum electrolytic capacitor designed for high-voltage, long-life general-purpose applications. It delivers 68 µF capacitance at a 400 V rating in a compact φ12.5×35.5 mm can with 5 mm lead spacing.

Engineered for durability, this capacitor offers a 10,000-hour endurance at 105°C, controlled leakage and loss characteristics, and ripple current capability across low and high frequencies—making it suitable where sustained high-voltage filtering and energy storage are required within constrained board layouts.

Key Features

• Capacitance & Tolerance — 68 µF nominal with ±20% tolerance (120 Hz, 20°C) for predictable charge storage.
• High Voltage Rating — Rated for 400 V to support higher-voltage circuits and bulk energy applications.
• Long Life Endurance — Specified 10,000 hours at 105°C under DC bias plus rated ripple current; after this test the capacitor meets defined limits for capacitance change, tan δ and leakage current.
• Ripple Current Capability — 540 mA at 120 Hz (low frequency) and 810 mA at 10 kHz (high frequency) to handle real-world AC ripple across a range of switching and line frequencies.
• Leakage Current — Measured leakage current of 1,188 µA (after 1 minute at 20°C) consistent with the series specification formula.
• Loss Angle (tan δ) — Maximum tan δ of 0.24 at the 400 V rating for predictable dissipation characteristics.
• Temperature Range — Operational from −40°C to +105°C to cover a wide range of environmental conditions.
• Compact Radial Package — φ12.5×35.5 mm can (3.55×1.25 cm) with 5 mm lead spacing and radial leads for through-hole mounting and straightforward assembly; supplied in bulk/bag packaging for production use.

Typical Applications

• General-purpose high-voltage circuits — Filtering and energy storage where a 400 V rating and 68 µF capacity are required for sustained operation.
• Power-supply smoothing — Accommodates ripple currents up to 540 mA at 120 Hz and higher-frequency ripple up to 810 mA at 10 kHz for smoothing after rectification or switching stages.
• Industrial electronics — Suitable for equipment requiring long-life capacitors rated for extended operation at elevated temperatures (10,000 h at 105°C).

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage designs without upsizing footprint.
• Designed for long service life: 10,000-hour endurance at 105°C provides predictable aging characteristics for maintenance planning and lifecycle cost control.
• Broad ripple tolerance: Rated ripple currents at both low and high frequencies support mixed-frequency power environments and switching supplies.
• Compact radial form factor: φ12.5×35.5 mm can and 5 mm lead spacing deliver a small footprint for through-hole assemblies where board space is limited.
• Controlled leakage and loss: Specified leakage current and tan δ values enable predictable standby and dissipation behavior in designs.
