UCY2G270MHD

The UCY2G270MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UCY series. It is a radial lead, polarized capacitor rated at 27 µF and 400 V, designed for applications that require sustained ripple handling and long operating life in compact packages.

Targeted use cases include automotive and power electronics applications such as power supplies and ballasts where durable, high-voltage filtering and smoothing are required. Key value propositions are high ripple-current capability, a long endurance rating at elevated temperature, and AEC-Q200 qualification.

Key Features

• Capacitance & Voltage — 27 µF rated capacitance at 400 V provides energy storage and filtering for high-voltage circuits.
• High Ripple Current — Low-frequency ripple current 360 mA (120 Hz) and high-frequency ripple current 720 mA (100 kHz) for demanding power applications.
• Long Endurance — Rated life of 10,000 hours at 105 °C under specified conditions, supporting long-term operation in elevated-temperature environments.
• Temperature Range — Operating range from −40 °C to 105 °C for use across broad thermal conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) 0.24 measured at 20 °C, 120 Hz, suitable for frequency-dependent performance evaluation.
• Leakage Current — Specified leakage current of 532 µA for predictable DC performance.
• Compact Radial Package — Can dimensions φ12.5 × 20 mm with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm); available as bulk (no terminal forming) or bag packing.
• Automotive-Grade Qualification — AEC-Q200 rated and RoHS compliant, supporting automotive and high-reliability design requirements.

Typical Applications

• Automotive Power Electronics — Bulk energy storage and ripple suppression in automotive DC/DC converters and power-supply modules where AEC-Q200 qualification is required.
• Power Supplies and Ballasts — Input/output smoothing and high-voltage filtering in industrial and lighting ballast circuits, leveraging high ripple capability and 400 V rating.
• High-Voltage Filtering — Smoothing and decoupling in 400 V-class power conversion and conditioning circuits that need compact, long-life capacitors.

Unique Advantages

• High ripple-current handling: Rated ripple currents at both low and high frequencies reduce thermal stress in power circuits and help maintain stability under dynamic load.
• Extended high-temperature life: 10,000-hour endurance at 105 °C supports reliable long-term operation in hot environments and constrained cooling conditions.
• Automotive-capable qualification: AEC-Q200 rating provides confidence for designs targeting automotive and other demanding applications.
• Compact radial package: φ12.5 × 20 mm can size and 5 mm lead spacing deliver a small footprint for space-constrained boards while maintaining robust lead connections.
• Predictable dielectric behavior: Specified tan δ and leakage current enable accurate design margining for frequency-dependent and DC performance.
• RoHS compliant and production-ready: RoHS compliance and mass-production status support regulatory needs and supply continuity.
