UCY2E331MHD

The UCY2E331MHD is a high-reliability, miniature aluminum electrolytic capacitor in a radial-lead can package. It delivers 330 µF capacitance at a 250 V rating with a polarized radial-lead form factor suited to through-hole assemblies.

Designed for applications that require sustained ripple handling and long operating life, this AEC-Q200‑rated, RoHS‑compliant part targets demanding industrial and automotive electronic systems where temperature endurance and predictable performance matter.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 250 V and tolerance of −20% to +20%.
• High ripple capability — Specified ripple current of 1.6 A at 120 Hz (low frequency) and 3.2 A at 100 kHz (high frequency) to support high‑ripple DC circuits.
• Loss characteristics — tan δ (DF) of 0.20 measured at 20°C and 120 Hz for predictable impedance behavior in AC conditions.
• Leakage current — Specified leakage current of 3400 µA to aid design margin calculations for bias and standby conditions.
• Long life / Endurance — Rated for 12,000 hours at 105°C under DC bias plus rated ripple current (10000 hours for certain sizes per series limits), supporting extended field life.
• Temperature range — Operating from −40°C to +105°C for wide environmental compatibility.
• Compact radial package — Can-style radial lead package with dimensions φ18 × 46 mm (L: 4.6 cm × D: 1.8 cm), lead spacing 7.5 mm (±0.5 mm), and polarized configuration for easy through-hole placement.
• Qualification & compliance — AEC‑Q200 rating listed and RoHS compliant for regulated and automotive-grade designs.
• Packaging options — Available bulk (no terminal forming) or bag packing to match assembly and handling preferences.

Typical Applications

• Power supplies — Suited for filtering and energy storage in power supply circuits where sustained ripple current and long life are required.
• Ballasts and high‑ripple DC circuits — Designed for ballast applications and other circuits exposed to high ripple currents.
• Automotive electronics — AEC‑Q200 qualification supports use in automotive electronic modules that demand temperature endurance and durability.

Unique Advantages

• High ripple tolerance: 1.6 A at 120 Hz and 3.2 A at 100 kHz let designers manage large AC components on DC rails without upsizing.
• Long operational life: 12,000‑hour endurance at 105°C provides predictable aging and supports long maintenance intervals.
• Wide temperature window: −40°C to +105°C operation enables deployment across harsh environmental conditions.
• Automotive‑grade qualification: AEC‑Q200 listing supports use in regulated automotive and transportation applications.
• Compact radial can: φ18 × 46 mm size with 7.5 mm lead spacing balances board space and capacity for through‑hole assemblies.
• Regulatory compliance: RoHS compliance simplifies selection for designs targeting restricted‑substance requirements.
