UCY2H330MHD3

The UCY2H330MHD3 is a miniature aluminum electrolytic capacitor in Nichicon’s UCY series, configured as a radial‑lead, high‑reliability device. It delivers 33 µF at a 500 V rated voltage with design attributes targeted at high ripple current handling and extended life under elevated temperature.

Engineered for demanding power applications including automotive systems, this part combines a compact φ18 × 25 mm can, AEC‑Q200 qualification, and a rated operating temperature range of −40°C to +105°C for robust performance in harsh environments.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance with ±20% tolerance and a 500 V rated voltage for high‑voltage power circuits.
• High Ripple Current — Supports 350 mA low‑frequency ripple current at 120 Hz and 700 mA high‑frequency ripple current at 100 kHz, enabling improved filtering in switching and ballast applications.
• Long Life / High Reliability — Endurance rated for 10,000 hours at 105°C, providing extended operational life under thermal stress.
• Wide Temperature Range — Specified to operate from −40°C to +105°C to accommodate a broad set of environmental conditions.
• Electrical Losses — Tangent of loss angle (tan δ) of 0.24 measured at 20°C and 120 Hz for the 500 V rating, useful for assessing dissipation and ESR behavior.
• Form Factor & Mounting — Radial lead can package (φ18 × 25 mm) with 7.5 mm lead spacing (±0.5 mm) for through‑hole assemblies; available in bulk or bag packing.
• Leakage Current — Specified leakage current of 760 µA for predictable standby and bias performance.
• Automotive‑grade Qualification — AEC‑Q200 rated, supporting use in automotive electronics where that qualification is required.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Power Supplies — Bulk or decoupling capacitor for high‑voltage power supplies and DC link stages where high ripple handling and long life are required.
• Ballasts and Lighting Electronics — Filtering and energy storage in ballast circuits, leveraging high ripple current capability and voltage rating.
• Automotive Electronics — Suitable for in‑vehicle power modules and control units that require AEC‑Q200 qualification and operation across −40°C to +105°C.

Unique Advantages

• High‑Voltage Capability: 500 V rating enables use in high‑voltage power and ballast applications without series stacking.
• Designed for High Ripple: Rated ripple currents at both low and high frequencies reduce thermal buildup and extend service life in switching environments.
• Long Endurance at Elevated Temperature: 10,000 hours at 105°C delivers predictable lifetime performance under continuous load and heat.
• Compact Radial Can: φ18 × 25 mm body with radial leads and 7.5 mm lead spacing balances board space and ease of through‑hole assembly.
• Automotive Qualification: AEC‑Q200 rating provides an established qualification path for automotive and similarly demanding applications.
• Regulatory Compliance: RoHS compliance supports use in regulated product designs.
