UCY2G330MHD

The UCY2G330MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series, rated at 33 µF and 400 V. It is a miniature, polarized can-style capacitor engineered for high ripple current handling and extended endurance in elevated-temperature environments.

Designed for power supply and ballast applications and qualified to AEC-Q200, this part addresses high-voltage, high-reliability needs found in automotive and industrial power electronics where long life and thermal robustness matter.

Key Features

• Capacitance & Tolerance — 33 µF with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 400 V DC rating for high-voltage circuits.
• Ripple Current Performance — Low-frequency ripple current 385 mA at 120 Hz and high-frequency ripple current 770 mA at 100 kHz, supporting applications with significant AC components.
• Loss Angle (tan δ) — tan δ = 0.24 specified at 20°C, 120 Hz for impedance/loss characterization.
• Leakage Current — Specified leakage current of 628 µA.
• Temperature & Endurance — Operating range −40°C to +105°C and designed for 12,000 hours of life at 105°C under rated conditions.
• Mechanical & Mounting — Radial lead can package, dimension φ12.5 × 25 mm with 5 mm lead spacing (±0.5 mm lead spacing tolerance); available in bulk (no terminal forming) or bag packing.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for regulated-environment designs.
• Polarized — Standard polarized aluminum electrolytic construction for DC applications.

Typical Applications

• Power Supplies — DC link and bulk smoothing in high-voltage power supplies where 400 V rating and high ripple capability reduce heating and extend service life.
• Ballasts and Lighting Electronics — Supports ballast circuits where stable capacitance and high ripple endurance are required at elevated temperatures.
• Automotive Power Electronics — Suited to automotive power modules and auxiliary power circuits, backed by AEC-Q200 qualification and long-life specification at 105°C.

Unique Advantages

• High-voltage capability: 400 V rating enables use in elevated-voltage DC systems without series stacking.
• High ripple-current handling: 385 mA (120 Hz) and 770 mA (100 kHz) ratings help minimize internal heating under AC stress, improving reliability.
• Long elevated-temperature life: 12,000 hours at 105°C provides proven endurance for designs exposed to sustained high temperatures.
• AEC-Q200 qualified: Offers an industry-recognized qualification for automotive-grade reliability where specified.
• Space-efficient radial package: φ12.5 × 25 mm can with 5 mm lead spacing simplifies layout in compact power assemblies.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements.
