UCY2D271MHD

The UCY2D271MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a radial-lead, polarized can-type capacitor specified at 270 µF and 200 V, designed for demanding power applications that require high ripple handling and long operational life.

With AEC-Q200 qualification, a wide operating temperature range of −40°C to 105°C, and a rated endurance of 12,000 hours at 105°C, this part targets power supply and ballast designs as well as automotive-grade electronic systems that require robust, long-life bulk energy storage.

Key Features

• Capacitance and Voltage: 270 µF nominal capacitance with a rated voltage of 200 V and capacitance tolerance of −20% to +20% for bulk energy storage and smoothing.
• High ripple current capability: Low-frequency ripple current 1.4 A at 120 Hz and high-frequency ripple current 2.8 A at 100 kHz, supporting power rails with significant AC ripple content.
• Long endurance at elevated temperature: Rated life of 12,000 hours at 105°C under DC bias plus rated ripple, enabling extended service in high-temperature environments.
• Loss characteristics: Dissipation factor (tanδ) 0.20 measured at 20°C, 120 Hz, supporting predictable ESR-related behavior in filtering and smoothing applications.
• Leakage current: Specified leakage current of 2260 µA, aligned with typical aluminum electrolytic behavior for initial hold characteristics.
• Compact radial can package: φ16 × 35.5 mm can with 7.5 mm lead spacing (lead spacing tolerance ±0.5 mm), delivered in bulk or bag packing for easy through-hole assembly.
• Environmental and qualification: RoHS compliant and AEC-Q200 rated, suitable for regulated manufacturing and automotive-grade qualification workflows.

Typical Applications

• Power supplies: Bulk smoothing and energy storage for DC power rails where high ripple current capability and long life at elevated temperature are required.
• Ballasts and lighting drivers: Filtering and ripple suppression in ballast circuits where sustained ripple handling and thermal endurance matter.
• Automotive electronics: Energy buffering and decoupling in automotive systems, supported by AEC-Q200 qualification and −40°C to 105°C operating range.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 1.4 A (120 Hz) and 2.8 A (100 kHz) allow the part to handle demanding AC components on power rails without rapid degradation.
• Extended high-temperature life: 12,000-hour endurance at 105°C provides predictable long-term performance in hot operating environments.
• AEC-Q200 qualification: Enables use in applications that require automotive-grade reliability and alignment with automotive component qualification practices.
• Compact radial form factor: φ16 × 35.5 mm can and 7.5 mm lead spacing deliver a balance of capacitance density and through-hole assembly convenience.
• Regulatory compliance: RoHS compliance supports deployment in regulated production environments.
