UCA2C680MHD6

The UCA2C680MHD6 from Nichicon is a miniature radial lead aluminum electrolytic capacitor in the UCA series, rated 68 µF at 160 V. It is designed for high‑ripple, long‑life applications such as power supplies and ballast circuits where compact high‑voltage filtering is required.

Key attributes include a high rated ripple current (970 mA at 100 kHz), a wide operating temperature range (−25 °C to +105 °C), and a guaranteed load life of 12,000 hours at 105 °C, delivering reliable performance in demanding power environments.

Key Features

• Capacitance & Voltage: 68 µF nominal capacitance with a rated voltage of 160 V and tolerance of ±20% (at 120 Hz, 20 °C).
• High Ripple Current: Rated ripple current of 970 mA at 100 kHz; frequency coefficient data available for lower frequencies (e.g., 0.50 at 120 Hz, 1.00 at 100 kHz).
• Leakage Current Specified: Leakage current limited to 0.04CV + 100 µA (resulting in 535.2 µA for this part at the rated voltage and capacitance).
• Long Load Life: Endurance of 12,000 hours at +105 °C under rated DC bias plus rated ripple current, with specified limits on capacitance change, tan δ, and leakage.
• Temperature Range: Operational from −25 °C to +105 °C for broad ambient applicability.
• Compact Radial Package: Radial can construction with 7.5 mm lead spacing and a case size approximately 16 mm × 20 mm (φD × L), suitable for through‑hole mounting.
• Polarized, General‑Purpose Use: Polarized aluminum electrolytic designed for general‑purpose high‑voltage filtering and smoothing applications.
• RoHS Compliant: Meets RoHS directive requirements.

Typical Applications

• Power Supplies: Bulk filtering and smoothing in high‑voltage power supply rails where compact size and high ripple capability are needed.
• Ballast Circuits: Filtering and energy storage for ballast and lamp‑drive circuits that demand sustained ripple handling and thermal endurance.
• General High‑Voltage Filtering: Decoupling and noise suppression in equipment requiring a 160 V, 68 µF polarized capacitor with sustained high‑frequency ripple performance.

Unique Advantages

• High ripple tolerance: 970 mA at 100 kHz allows smaller, cooler designs in high‑frequency power stages compared with lower‑ripple parts.
• Designed for long service life: 12,000 hours at 105 °C provides predictable aging characteristics for long‑running equipment.
• Compact footprint: Small radial can (≈16 mm × 20 mm) and 7.5 mm lead spacing help reduce board area while retaining high voltage capability.
• Specified leakage behavior: Leakage current defined by 0.04CV + 100 µA gives clear expectations for startup and idle current draw.
• Wide operating temperature: −25 °C to +105 °C supports applications with varied ambient conditions.
• RoHS compliance: Conforms to RoHS directive for regulatory alignment in modern product builds.
