UCA2G680MHD

The UCA2G680MHD is a miniature, radial-lead aluminum electrolytic capacitor designed for high ripple current and extended operational life. It delivers 68 µF at a rated voltage of 400 V in a compact can-style package, offering robust performance for power electronics.

Targeted at general-purpose power applications, this part is well suited for power supply and ballast circuits that require high ripple handling, long endurance at elevated temperatures, and straightforward radial-lead mounting.

Key Features

• Electrical performance — Rated capacitance 68 µF with ±20% tolerance and rated voltage 400 V; designed for polarized DC applications.
• High ripple capability — Rated ripple current 1.0 A at 100 kHz and 105 °C, and 500 mA at 120 Hz, enabling reliable filtering in high-frequency power stages.
• Long operational life — Load-life rated for 12,000 hours at 105 °C, providing extended service life under elevated-temperature stress.
• Thermal range and loss characteristics — Operating temperature range from –25 °C to +105 °C with a tangent of loss angle (tan δ) of 0.20 at the 400 V rating (measured at 120 Hz, 20 °C).
• Leakage current — Specified leakage current of 1,188 µA at 20 °C after 1 minute, enabling predictable bias current planning.
• Compact radial-can package — Radial lead mounting with 7.5 mm lead spacing and physical size L: 3.05 × D: 1.8 cm for space-conscious board designs.
• RoHS compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements for restricted substances.

Typical Applications

• Power supplies — DC link and output filtering where 400 V rating and high ripple capability help smooth high-frequency switching currents.
• Ballasts — Suitable for ballast circuits that require stable capacitance and high ripple endurance at elevated temperatures.
• General-purpose power electronics — Radial-lead mounting and compact size make it practical for a range of general-purpose power applications needing long life and reliable performance.

Unique Advantages

• High-frequency ripple handling: Rated 1.0 A at 100 kHz and 105 °C, supporting demanding switching and high-frequency load conditions.
• Extended high-temperature life: 12,000-hour rated life at 105 °C reduces replacement frequency in thermal-stressed environments.
• Compact, installer-friendly package: Radial can with 7.5 mm lead spacing and a small footprint (3.05 × 1.8 cm) eases placement in constrained layouts.
• Predictable electrical characteristics: Specified leakage current and tan δ enable accurate thermal and loss budgeting in designs.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for many markets.
