UCY2E271MHD

The UCY2E271MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UCY series. It is a radial-lead, polarized capacitor specified at 270 µF and 250 V, designed for demanding power filtering and energy storage roles.

Engineered for long life and high ripple capability, this part targets power supply and ballast applications and is suitable for automotive systems where AEC-Q200 qualification is required. It offers a wide operating range from −40°C to +105°C with rated endurance at elevated temperatures.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 250 V; capacitance tolerance ±20% at 120 Hz, 20°C.
• High Ripple Current — Designed for robust ripple handling: 1.45 A at 120 Hz (low frequency) and 2.9 A at 100 kHz (high frequency), enabling effective smoothing in power circuits.
• Long Life & Endurance — Life rating of 12,000 hours at 105°C under DC bias plus rated ripple current (per UCY series endurance specification).
• Thermal Range — Operating temperature from −40°C to +105°C for reliable performance across harsh environments.
• Loss and Leakage — Tangent of loss angle (tanδ) max 0.20 at 120 Hz, 20°C for 250 V units; specified leakage current 2,800 µA.
• Package & Form Factor — Radial-lead can, size φ18 × 35.5 mm (L: 3.55 × D: 1.8 cm), lead spacing 7.5 mm (±0.5 mm), suitable for through-hole assemblies.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant, addressing quality and regulatory requirements for automotive and industrial designs.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to support PCB assembly and inventory workflows.

Typical Applications

• Automotive Power Supplies — Bulk energy storage and ripple filtering in automotive electronic power systems where AEC-Q200 qualification is required.
• Power Supply Filters — Smoothing and decoupling in industrial and commercial power supplies and converters, leveraging high ripple ratings and long life.
• Ballasts and Lighting Electronics — Energy storage and ripple mitigation in ballast circuits as identified in the UCY series guidance.

Unique Advantages

• High Ripple Handling: 1.45 A (120 Hz) and 2.9 A (100 kHz) ratings let designers reduce additional bulk capacitance while maintaining stable filtering under load.
• Extended High-Temperature Life: 12,000-hour endurance at 105°C supports longer maintenance intervals and higher reliability in thermally stressed applications.
• Automotive-Grade Qualification: AEC-Q200 rating provides an established qualification pathway for use in automotive and similarly demanding applications.
• Compact Through-Hole Form: φ18 × 35.5 mm radial can with 7.5 mm lead spacing delivers a space-efficient, serviceable solution for through-hole assemblies.
• Regulatory Compliance: RoHS compliance ensures adherence to current environmental directives.
• Flexible Packaging: Bulk or bag packing options simplify stocking and assembly integration for production or prototyping needs.
