UCY2D820MHD9

The UCY2D820MHD9 is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UCY series, designed for high ripple current and long life in compact power assemblies. It delivers 82 µF capacitance at a 200 V rating in a φ12.5 × 20 mm can with 5 mm lead spacing.

Targeted for power electronics and automotive applications, the UCY2D820MHD9 combines a wide operating temperature range and AEC‑Q200 qualification for reliable operation in demanding environments such as power supplies and ballast circuits.

Key Features

• Capacitance & Voltage — 82 µF capacitance with a 200 V rated voltage and a tolerance of −20% to +20% at 20°C, 120 Hz.
• High Ripple Current Capability — Low‑frequency ripple current of 645 mA at 120 Hz and high‑frequency ripple current of 1.29 A at 100 kHz, enabling effective smoothing in power stages.
• Long Life and High Temperature Endurance — Rated life of 10,000 hours at 105°C, designed for sustained operation under elevated temperature and load conditions.
• Low Loss (tan δ) — Dissipation factor (tan δ) 0.20 measured at 20°C, 120 Hz, supporting efficient energy handling.
• Compact Radial Package — φ12.5 × 20 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assembly.
• Polarized Aluminum Electrolyte — Standard polarized construction for DC smoothing and bulk energy storage.
• AEC‑Q200 Qualified — Meets AEC‑Q200 requirements for components intended for automotive and similarly demanding applications.
• RoHS Compliant — Conforms to RoHS directive requirements.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production needs.

Typical Applications

• Power Supplies — Bulk smoothing and ripple suppression in offline and DC power supply stages where 200 V rating and high ripple current capability are required.
• Ballast and Lighting Electronics — Designed for ballast circuits requiring compact capacitors with high ripple endurance and long life at elevated temperatures.
• Automotive Power Electronics — Suitable for automotive electronic modules and subsystems that require AEC‑Q200 qualified passive components and extended high‑temperature endurance.
• Industrial Power Modules — Energy storage and filtering in industrial converters and control electronics operating across −40°C to +105°C.

Unique Advantages

• High Ripple Handling — Specified ripple currents (645 mA at 120 Hz; 1.29 A at 100 kHz) allow designers to minimize additional filtering stages for compact power designs.
• Extended Endurance at High Temperature — 10,000‑hour life at 105°C supports long service intervals and predictable aging in hot locations.
• Automotive‑Grade Qualification — AEC‑Q200 qualification provides confidence for integration into automotive and other high‑reliability systems.
• Compact Footprint — φ12.5 × 20 mm radial can with 5 mm lead spacing saves PCB area while providing substantial capacitance and voltage rating.
• Low Dissipation Factor — tan δ of 0.20 (120 Hz, 20°C) contributes to efficient operation and reduced self‑heating under AC stress.
• Production‑Ready Packaging — Bulk and bag packing options support both prototyping and volume assembly flows.
