UCY2V330MHD3

The UCY2V330MHD3 from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can intended for demanding power applications. It delivers 33 µF at a 350 V rating in a compact φ16 × 20 mm package with 7.5 mm lead spacing, combining high ripple-current capability with extended load life for robust power-supply and ballast designs.

Designed for environments requiring long endurance and stable performance across a wide temperature range, the UCY2V330MHD3 is AEC-Q200 qualified and RoHS compliant, making it suitable for automotive and industrial power electronics where sustained operation at elevated temperature is required.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance with a 350 V working voltage and a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High ripple-current handling — Low-frequency ripple current 450 mA at 120 Hz and high-frequency ripple current 900 mA at 100 kHz, with frequency coefficients available for scaling ripple at other frequencies.
• Long endurance — Load life of 10,000 hours at 105°C, meeting endurance expectations for continuous high-temperature operation.
• Loss characteristics — Dissipation factor (tanδ) of 0.24 (max.) measured at 20°C, 120 Hz for the 350 V rating.
• Leakage current — Specified leakage current of 562 µA, consistent with electrolytic performance expectations at rated conditions.
• Mechanical and packaging — Radial lead, polarized aluminum can (φ16 × 20 mm) with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Environmental and qualification — AEC-Q200 qualified and RoHS compliant for regulated environments and automotive-grade applications.
• Operating range — Specified for −40°C to +105°C operation to support a broad set of thermal environments.

Typical Applications

• Power supplies — Bulk and decoupling capacitance in AC/DC and DC/DC converters where 350 V voltage margin and high ripple handling are required.
• Ballasts — Suited for ballast circuits that demand compact capacitors with sustained ripple performance and long life at elevated temperature.
• Automotive power electronics — AEC-Q200 qualification and extended endurance make this capacitor appropriate for automotive electronic modules requiring robust energy storage and ripple tolerance.

Unique Advantages

• High ripple-current capacity: Rated at 450 mA (120 Hz) and 900 mA (100 kHz), enabling lower temperature rise and reliable operation under significant AC stress.
• Extended life at elevated temperature: 10,000 hours endurance at 105°C provides predictable aging and long-term performance for continuously loaded designs.
• Compact radial can footprint: φ16 × 20 mm package with 7.5 mm lead spacing delivers a space-efficient solution for through-hole assemblies.
• Automotive-grade qualification: AEC-Q200 status supports use in automotive systems and other applications demanding component-level qualification.
• Measured dielectric characteristics: Specified tanδ (0.24 max.) and a defined leakage current (562 µA) aid engineering trade-offs for ESR/DF and standby losses.
• Regulatory compliance: RoHS compliance supports environmentally regulated product builds.
