UCY2C271MHD

The UCY2C271MHD is a radial-lead, miniature aluminum electrolytic capacitor from Nichicon's UCY series designed for high ripple current and long-life applications. It delivers 270 µF nominal capacitance at a 160 V rating with a compact φ18 × 25 mm can and 7.5 mm lead spacing.

Engineered for demanding power electronics, this high-reliability type offers extended endurance at elevated temperature (12,000 hours at 105°C), AEC-Q200 qualification, and RoHS compliance—making it suitable for automotive and other rugged, high-ripple environments.

Key Features

• Capacitance and Tolerance — 270 µF nominal with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 160 V DC rating for higher-voltage power rails.
• High Ripple Current — Low-frequency ripple current 1.235 A at 120 Hz and high-frequency ripple current 2.47 A at 100 kHz, supporting heavy ripple workloads.
• Long Endurance — Rated life of 12,000 hours at 105°C under DC bias plus rated ripple current (with performance recovery criteria per datasheet).
• Loss Characteristics — Tangent of loss angle (tan δ) max 0.20 at 20°C, 120 Hz for the 160 V rating.
• Leakage Current — Specified leakage current of 1,828 µA (measured after 1 minute at rated voltage, 20°C).
• Package and Mounting — Radial-lead can (φ18 × 25 mm) with 7.5 mm lead spacing (±0.5 mm); supplied Bulk (no terminal forming) or Bag packing.
• Environmental and Reliability — AEC-Q200 qualified and RoHS compliant; operating temperature range -40°C to +105°C.

Typical Applications

• Automotive Power Systems — Suitable for vehicle power electronics where AEC-Q200 qualification and high ripple handling are required.
• Power Supplies — Used for bulk filtering and smoothing on DC rails that demand sustained ripple endurance and high working voltage.
• Ballasts and High-Ripple Circuits — Designed for ballast and other high-ripple environments where long life at elevated temperature is needed.

Unique Advantages

• High ripple capability: Supports 1.235 A at 120 Hz and 2.47 A at 100 kHz, enabling reliable operation in heavy‑ripple power stages.
• Extended elevated-temperature life: 12,000 hours at 105°C provides predictable endurance for long-term designs.
• AEC-Q200 qualified: Provides a documented qualification level suitable for automotive-grade designs.
• Compact radial form factor: φ18 × 25 mm can with 7.5 mm lead spacing delivers high energy density in a small footprint.
• Controlled loss and leakage: tan δ ≤ 0.20 (120 Hz, 20°C) and specified leakage current support stable performance in power applications.
• RoHS compliant: Meets regulatory requirements for restricted substances.
