UCA2E680MHD6

The UCA2E680MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UCA series. It is a polarized, miniature can-style capacitor rated at 250 V with 68 µF capacitance and ±20% tolerance, designed for general-purpose power applications.

Engineered for high ripple handling and extended operating life, this part supports a wide operating temperature range (–25°C to +105°C) and a rated life of 12,000 hours at 105°C. It is RoHS compliant and marked with white lettering on a dark brown sleeve.

Key Features

• Rated electricals — 68 µF capacitance at 250 V with ±20% tolerance, polarized configuration for DC filtering and bulk energy storage.
• High ripple current capability — Rated ripple current of 920 mA at 100 kHz and 460 mA at 120 Hz to support power supplies and high-frequency converters.
• Long operational life — Endurance specified at 12,000 hours at +105°C under DC bias plus rated ripple current.
• Controlled losses — Tangent of loss angle (tan δ) ≤ 0.15 at 120 Hz and 20°C, enabling predictable dissipation characteristics.
• Leakage current specification — After 1 minute at rated voltage and 20°C, leakage current not more than 0.04CV + 100 µA (where C is µF and V is volts).
• Compact radial-can package — Physical dimensions L: 2.0 cm × D: 1.8 cm, seated height up to 2.0 cm, 7.5 mm lead spacing (±0.5 mm) for through-hole PCB placement.
• Packaging & marking — Supplied in bulk with bag packing; sleeve marked with white letters on dark brown; RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies — Bulk decoupling and smoothing where high ripple handling and long life are required.
• Ballasts and lighting drivers — Designed for ballast application environments that demand sustained ripple endurance and stable capacitance.
• General-purpose industrial electronics — Suitable for embedded power circuits and control electronics requiring a compact, high-voltage electrolytic solution.

Unique Advantages

• High ripple tolerance: Rated ripple current values at both 100 kHz and 120 Hz provide flexibility across switching and line-frequency designs.
• Extended life at elevated temperature: 12,000-hour rating at +105°C supports long-term reliability in thermally demanding applications.
• Predictable electrical behavior: Specified tan δ and leakage current formula allow engineers to model dissipation and standby losses accurately.
• Compact, PCB-friendly form factor: Radial lead spacing and small can dimensions save board area while remaining easy to mount.
• Regulatory compliance: RoHS conformity facilitates use in markets with restricted-substance requirements.
