UCY2C331MHD6

The UCY2C331MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series configured in a radial-lead can. It delivers 330 µF at 160 V with a polarized radial-lead package designed for applications that require sustained ripple handling and long operational life.

Targeted use cases include power supplies and ballast circuits as well as automotive electronics that benefit from a compact capacitor with high ripple capability, extended life at elevated temperature, and AEC-Q200 qualification.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance rated at 160 V with a tolerance of -20% to +20%.
• High Ripple Current — Low-frequency ripple current of 1.445 A at 120 Hz and high-frequency ripple current of 2.89 A at 100 kHz, supporting demanding power filtering duties.
• Low Loss (tan δ) — Dissipation factor (tan δ) is 0.20 measured at 20°C and 120 Hz for the 160 V rating, enabling efficient energy handling.
• Long Life & Endurance — Rated for 12,000 hours at 105°C under D.C. bias plus rated ripple current; endurance limits for capacitance, tan δ and leakage current are specified after life test.
• Operating Temperature Range — Specified for -40°C to +105°C to accommodate a wide range of ambient conditions.
• Leakage Current — Part-specific leakage current listed as 2,212 µA; datasheet leakage current condition: after 1 minute application at 20°C the limit is ≤ 0.04CV + 100 µA.
• Frequency Response — Frequency coefficients for rated ripple current: 50 Hz = 0.80, 120 Hz = 1.00, 1 kHz = 1.60, 10 kHz = 1.80, 100 kHz or more = 2.00.
• Package & Mechanical — Radial lead can, size φ18 × 25 L with lead spacing 7.5 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant as listed in product specifications and datasheet content.

Typical Applications

• Power Supplies — Bulk and output filtering where high ripple current capacity and low loss improve regulator stability and thermal performance.
• Ballast Circuits — Energy storage and ripple handling in ballast and lamp driver applications as noted in the UCY series datasheet.
• Automotive Electronics — High-reliability modules and control electronics that require AEC-Q200-qualified capacitors with long life at 105°C.

Unique Advantages

• High ripple capability: Rated ripple currents (1.445 A @120 Hz, 2.89 A @100 kHz) reduce heating under dynamic load and extend usable life in power circuits.
• Extended high-temperature life: 12,000 hours endurance at 105°C supports long-term reliability in elevated-temperature environments.
• AEC-Q200 qualification: Industry-recognized qualification that simplifies component selection for applications requiring enhanced reliability.
• Compact radial package: φ18 × 25 mm can with 7.5 mm lead spacing provides a space-efficient solution for through-hole assemblies.
• Predictable frequency performance: Published frequency coefficients allow engineers to scale ripple ratings across operating frequencies with confidence.
• Regulatory compliance: RoHS-compliant construction supports restricted-substance requirements.
