UCY2W820MHD

The UCY2W820MHD is a radial-leaded aluminum electrolytic capacitor offering 82 µF capacitance at a 450 V rating in a compact φ16 × 40 mm can. It combines high-voltage capability with elevated ripple current handling and a long rated life for demanding power applications.

Designed for industrial and automotive power electronics, this polarized capacitor delivers stable performance from −40°C to +105°C and is AEC‑Q200 qualified with RoHS compliance.

Key Features

• High voltage rating: 450 V rated voltage for high-voltage power rails and DC link applications.
• Capacitance and tolerance: 82 µF nominal with -20% to +20% (±20%) tolerance for predictable energy storage.
• High ripple current capability: Handles 750 mA at 120 Hz (low frequency) and 1.5 A at 100 kHz (high frequency), supporting both mains-frequency and high-frequency switching environments.
• Long endurance: Rated life of 12,000 hours at 105°C under rated voltage and ripple conditions for extended service in continuous-run applications.
• Loss characteristics: tan δ (DF) = 0.24 measured at 20°C, 120 Hz—useful for loss budgeting in design.
• Mechanical and mounting: Radial lead can (φ16 × 40 mm) with 7.5 mm lead spacing (±0.5 mm) for through-hole assemblies; packaging available in bulk or bag.
• Environmental and qualification: AEC‑Q200 rated and RoHS compliant for regulated and automotive sectors.

Typical Applications

• Automotive power systems: Energy smoothing and DC link support in in-vehicle power electronics where AEC‑Q200 qualification is required.
• Power supplies and converters: Bulk energy storage and ripple filtering on high-voltage rails in switch‑mode power supplies and DC–DC converters.
• Ballasts and lighting drivers: High-voltage filtering and lifetime performance suited to ballast applications.
• Industrial controls: Filtering and decoupling in motor drives, servo amplifiers, and other high-voltage industrial equipment.

Unique Advantages

• High-voltage capability: 450 V rating enables use on higher-voltage DC rails without series stacking.
• Broad ripple-handling range: Specified ripple current at both 120 Hz and 100 kHz allows the same component to address mains-frequency and high-frequency switching noise.
• Extended operating life: 12,000-hour endurance at 105°C provides long-term stability for continuous-duty designs.
• Automotive-grade qualification: AEC‑Q200 rating supports integration into designs targeting automotive and other high-reliability markets.
• Compact radial can: φ16 × 40 mm size and defined lead spacing simplify mechanical integration in through-hole assemblies.
• Regulatory compliance: RoHS conformity for use in regulated supply chains.
