UCY2D271MHD6

The UCY2D271MHD6 is a radial lead aluminum electrolytic capacitor offering 270 µF capacitance at a 200 V rating. It combines high ripple-current capability and long endurance in a compact radial can package suited for electronic power systems.

Designed for applications that require durable filtering and energy smoothing, this capacitor targets power supplies, ballast circuits and automotive electronic modules where long life, temperature tolerance and high ripple handling are important.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current — Low-frequency ripple capability of 1.41 A at 120 Hz and high-frequency ripple capability of 2.82 A at 100 kHz, enabling effective smoothing across a range of switching frequencies.
• Long Endurance — Designed for 12,000 hours of load life at 105°C with DC bias plus rated ripple current, supporting extended service in thermal stress environments.
• Temperature Range — Operates from −40°C to +105°C to cover a wide range of ambient conditions.
• Leakage and Loss Characteristics — Leakage current specified as 2,260 µA (measured after 1 minute at 20°C) and tan δ (loss tangent) of 0.20 at 120 Hz, 20°C, for predictable loss and leakage behavior.
• Package & Mounting — Radial lead (can) construction with 7.5 mm lead spacing and compact dimensions (φ18 × 30.5 mm length), available in bulk/bag packing.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for regulated markets and automotive-grade durability expectations.
• Frequency Scaling — Ripple-current performance scales with frequency (example coefficients in series data: 120 Hz = 1.00; 100 kHz or more = 2.00), useful for estimating ripple capability at different operating frequencies.

Typical Applications

• Power Supplies — Bulk and output filtering in switching and linear supplies where high ripple handling and long life improve voltage stability.
• Ballasts and Lighting Controls — Energy smoothing and ripple reduction in ballast circuits as noted in the product series guidance.
• Automotive Electronics — Energy storage and filtering in vehicle electronics, leveraging AEC-Q200 qualification and extended temperature range for in-vehicle environments.

Unique Advantages

• High ripple tolerance: 1.41 A (120 Hz) and 2.82 A (100 kHz) ratings reduce thermal stress in high-frequency and low-frequency power systems.
• Extended operational life: 12,000 hours at 105°C under rated conditions supports longer maintenance intervals and product longevity.
• Automotive qualification: AEC-Q200 status indicates suitability for demanding applications that require component-level robustness.
• Wide temperature range: −40°C to +105°C operation enables deployment across harsh ambient conditions.
• Compact radial form factor: φ18 × 30.5 mm can and 7.5 mm lead spacing provide a space-efficient option for through-hole layouts.
• Regulatory compliance: RoHS compliance simplifies use in regulated end-products.
