UCS2C680MHD

The UCS2C680MHD is a miniature, radial-leaded aluminum electrolytic capacitor from Nichicon’s UCS series. It delivers 68 µF capacitance at 160 V with a polarized radial can package designed for general-purpose power applications.

Engineered for applications that require high ripple-current handling and extended operating life, this capacitor is suited for power supplies and ballast circuits and is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Electrical Core — 68 µF rated capacitance with a 160 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Capability — Rated ripple current of 590 mA at 120 Hz and 1.18 A at 100 kHz to support high-pulsed and high-frequency power filtering.
• Long Life / High Temperature Endurance — Designed to withstand load life of 8,000–10,000 hours at +105°C (specified lifetime listing: 10,000 h at 105°C).
• Reliability Characteristics — Endurance specifications include capacitance change within ±20% and tan δ within 200% of initial values after life test; leakage current defined by datasheet formula (≤ 0.04CV + 100 µA after 1 minute at 20°C).
• Compact Radial Can Package — Radial lead mounting with 5 mm lead spacing and a compact footprint (length 2.0 cm × diameter 1.25 cm) suitable for space-constrained boards.
• Operating Range — Rated for operation from −40°C to +105°C.
• Environmental Compliance — RoHS compliant to 2011/65/EU and (EU)2015/863.

Typical Applications

• Power Supplies — Bulk smoothing and ripple suppression in AC/DC and DC/DC converter outputs where sustained ripple performance is required.
• Ballasts and Lighting Electronics — Filtering and energy storage in ballast circuits as indicated by series application suitability.
• General-Purpose Industrial Power — Decoupling and transient absorption in industrial control and power distribution modules.

Unique Advantages

• High ripple-handling capability: Specified ripple currents at both low and high frequencies (590 mA at 120 Hz, 1.18 A at 100 kHz) reduce thermal stress in high-pulse environments.
• Extended high-temperature life: Life rating up to 10,000 hours at +105°C provides predictable longevity in hot operating conditions.
• Compact radial can footprint: Small dimensions (2.0 cm × 1.25 cm) and 5 mm lead spacing enable use where PCB space is limited.
• Defined reliability metrics: Endurance limits and leakage current formula are published, supporting engineering verification and qualification.
• Regulatory compliance: RoHS compliance (2011/65/EU, (EU)2015/863) supports use in restricted-substance environments.
