UCY2C271MHD6

The UCY2C271MHD6 is a radial-lead, miniature aluminum electrolytic capacitor in Nichicon’s UCY series designed for high ripple current and long life in demanding environments. This polarized 270 µF, 160 V capacitor delivers robust performance for power supply and ballast applications, with electrical and mechanical specifications tuned for reliable operation up to 105°C.

Key value propositions include high ripple-current capability across low and high frequencies, AEC-Q200 qualification for demanding applications, and a compact radial-can package (φ12.5 × 40 mm) with 5 mm lead spacing.

Key Features

• Electrical Capacity — 270 µF nominal capacitance with tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 160 V DC rating suitable for higher-voltage power circuits.
• Low Loss Characteristic — tan δ (DF) = 0.20 measured at 20°C, 120 Hz, supporting stable AC performance.
• High Ripple Current — Low-frequency ripple current 1.3 A at 120 Hz and high-frequency ripple current 2.6 A at 100 kHz, enabling effective smoothing in high-stress power rails.
• Long Endurance — Rated life of 12,000 hours at 105°C under rated DC bias plus rated ripple current (endurance specified in datasheet).
• Temperature Range — Operational from −40°C to +105°C to accommodate a wide range of thermal environments.
• Leakage Current — Specified leakage current of 1,828 µA for this part number.
• Compact Radial Package — φ12.5 × 40 mm can with 5 mm lead spacing (lead spacing tolerance ±0.5 mm); radial-lead mounting for through-hole assembly.
• Packaging Options — Supplied in Bulk (no terminal forming) or Bag packing to suit production needs.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant for regulated applications.
• Frequency Coefficient — Ripple-current frequency coefficients available (e.g., 1.00 at 120 Hz, 2.00 at 100 kHz or more) to size decoupling for the operating bandwidth.

Typical Applications

• Automotive Electronics — Use in automotive power-supply circuits where AEC-Q200 qualification, high ripple handling and long life at elevated temperatures are required.
• Power Supply Filtering — Smoothing and bulk energy storage in DC power supplies and converters that require high ripple-current capability.
• Ballast and Power Modules — Suited for ballast and related power modules where sustained ripple and thermal endurance are important.

Unique Advantages

• High ripple capability across frequencies: Rated for 1.3 A at 120 Hz and 2.6 A at 100 kHz, with documented frequency coefficients to scale ripple performance.
• Extended high-temperature life: 12,000-hour endurance at 105°C ensures predictable long-term behavior in thermally demanding applications.
• Automotive-grade qualification: AEC-Q200 qualification supports use in designs that require recognized component-level reliability standards.
• Compact radial package for through-hole assembly: φ12.5 × 40 mm can and 5 mm lead spacing provide a space-efficient solution for legacy and robust PCB layouts.
• Regulatory compliance: RoHS-compliant construction supports deployment in regulated markets.
• Production-ready availability: Listed as mass production with bulk and bag packing options for volume assembly.
