UCA2C680MHD

The UCA2C680MHD from Nichicon is a miniature aluminum electrolytic capacitor in the UCA series, designed as a standard radial‑lead type for general-purpose power applications. It delivers 68 µF nominal capacitance at a 160 V rating with a compact φ12.5 × 25 mm can and 5 mm lead spacing.

Engineered for high ripple current and extended operating life, this part supports demanding thermal environments with a rated temperature range of −25 °C to +105 °C and an endurance rating of 12,000 hours at 105 °C.

Key Features

• Electrical Characteristics — 68 µF nominal capacitance with ±20% tolerance; rated voltage 160 V. Tangent of loss angle (tan δ) specified at 0.15 (measured at 20 °C, 120 Hz).
• High Ripple Current Capability — Low-frequency ripple current 475 mA at 120 Hz and high-frequency ripple current 950 mA at 100 kHz, supporting effective filtering in power circuits.
• Leakage Current — Specified leakage current: 535.2 µA (measured per product test conditions).
• Long Life and Temperature Performance — Rated for 12,000 hours of endurance at 105 °C; operational range from −25 °C to +105 °C for stable performance in elevated-temperature applications.
• Mechanical and Mounting — Radial lead (polarized) package in a φ12.5 mm diameter × 25 mm length can; lead spacing 5.0 mm with ±0.5 mm tolerance for through‑hole PCB mounting.
• Packaging and Compliance — Available in bulk/bag packing; RoHS compliant.

Typical Applications

• Power Supplies — Filtering and smoothing in power supply circuits where 160 V rating and robust ripple performance are required.
• Ballast Circuits — Suited for ballast applications as indicated in product documentation, providing stable capacitance under load and temperature stress.
• General-Purpose Power Filtering — General-purpose use for decoupling and energy storage in mid-voltage electronic systems that benefit from long life at elevated temperature.

Unique Advantages

• High ripple handling: Specified ripple currents of 475 mA (120 Hz) and 950 mA (100 kHz) enable efficient suppression of AC ripple across a range of frequencies.
• Extended high‑temperature endurance: 12,000 hours at 105 °C provides predictable long-term behavior for designs exposed to sustained heat.
• Compact radial can: φ12.5 × 25 mm package with 5 mm lead spacing supports dense through‑hole layouts without sacrificing capacitance.
• Clear electrical limits: Defined tan δ, leakage current, and capacitance tolerance make it straightforward to validate performance in design simulations and qualification tests.
• RoHS compliant: Conforms to RoHS requirements for regulatory-driven designs.
