UCY2E330MHD3

The UCY2E330MHD3 from Nichicon is a miniature aluminum electrolytic capacitor in the UCY series, provided in a radial lead can package. It delivers high ripple current capability and long operational life for demanding power applications.

Designed for use in power supply and ballast applications and listed for automotive use, the device combines a compact footprint with high-temperature endurance and industry compliance to support robust system designs.

Key Features

• Electrical characteristics — 33 µF capacitance at a 250 V rated voltage with ±20% tolerance; polarized radial lead construction for standard power filtering and decoupling tasks.
• High ripple current capability — Rated ripple current of 400 mA at 120 Hz and 800 mA at 100 kHz, with frequency coefficient data supporting increased ripple handling at higher switching frequencies.
• Long life at elevated temperature — Engineered to withstand 10,000 to 12,000 hours of DC bias plus rated ripple current at +105°C, supporting long-term reliability in hot operating environments.
• Temperature range — Operates from –40°C to +105°C to cover a wide span of environmental and application conditions.
• Compact radial package — Small form factor with dimensions L: 2 × D: 1.25 cm and 5 mm lead spacing in a radial, can-style package suitable for through‑hole assembly.
• Reliability and compliance — AEC‑Q200 Qualified and RoHS compliant (2011/65/EU, (EU) 2015/863), indicating suitability for regulated and high‑reliability applications.
• Leakage and dissipation characteristics — Leakage current specification per datasheet (after 1 minute at 20°C ≤ 0.04CV + 100 µA) and tan δ performance defined by rated voltage for predictable loss and leakage behavior.

Typical Applications

• Power Supplies — Bulk smoothing, output filtering and decoupling in industrial and electronic power supply modules where high ripple handling and temperature endurance are required.
• Ballasts and Lighting — Energy storage and ripple management in ballast circuits and lighting power stages specified in the product description.
• Automotive Electronics — Power filtering and energy buffering in automotive modules, supported by AEC‑Q200 qualification and extended temperature rating.

Unique Advantages

• High ripple tolerance at switching frequencies: 800 mA rating at 100 kHz and documented frequency coefficients reduce thermal stress in high‑frequency power stages.
• Long life under load: Rated for 10,000–12,000 hours at +105°C under DC bias plus ripple, enabling extended maintenance intervals and predictable end‑of‑life planning.
• Compact, through‑hole form factor: Radial can construction with small L × D footprint and 5 mm lead spacing simplifies replacement and prototyping in space‑constrained designs.
• Industry compliance for reliability: AEC‑Q200 qualification and RoHS compliance support deployment in regulated and safety‑conscious systems.
• Measured leakage and loss characteristics: Datasheet‑specified leakage current and tan δ values provide predictable behavior for precision power designs.
