UCY2C820MPD9

The UCY2C820MPD9 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a radial-lead polarized capacitor specified at 82 µF and 160 V, designed for demanding power applications.

Engineered for high ripple handling and extended life, this part offers a rated operating range of −40°C to 105°C, AEC-Q200 qualification, RoHS compliance and 12,000-hour endurance at 105°C, making it suitable for power supply smoothing, ballast circuits and automotive electronics that require reliable, long-term performance.

Key Features

• Electrical ratings — 82 µF capacitance at 160 V, with capacitance tolerance of −20% to +20% and polarization for DC applications.
• High ripple current capability — Rated ripple current of 455 mA at 120 Hz and 910 mA at 100 kHz to support high-demand filtering and decoupling in power circuits.
• Low dissipation factor — tanδ (DF) of 0.20 measured at 20°C, 120 Hz, reducing loss under AC ripple conditions.
• Long life and endurance — Rated for 12,000 hours at 105°C under rated DC bias plus ripple current; endurance limits for capacitance, tanδ and leakage current are defined after life test.
• Compact radial package — φ10 × 25 mm body with 5.0 mm lead spacing (±0.5 mm), radial can-style package for through-hole mounting and straightforward PCB layout.
• Leakage current specification — Specified leakage current of 624.8 µA, supporting predictable bias behavior after voltage application.
• Compliance and qualification — AEC-Q200 qualified and RoHS compliant; produced in mass-production packaging options (bulk / bag).

Typical Applications

• Power supplies — Smoothing and bulk decoupling in DC power supplies where high ripple current capability and low DF improve efficiency and thermal performance.
• Ballasts and lighting electronics — Filtering and energy buffering in ballast circuits that require sustained ripple handling and long operational life.
• Automotive electronics — Energy storage and decoupling in in-vehicle power systems where AEC-Q200 qualification and a −40°C to 105°C operating range are required.

Unique Advantages

• High ripple tolerance: Dual ripple ratings (455 mA at 120 Hz, 910 mA at 100 kHz) allow designers to specify a single capacitor for a wide range of switching and line-frequency conditions.
• Extended high-temperature life: 12,000-hour rating at 105°C provides predictable long-term performance in thermally stressed environments.
• Automotive-grade qualification: AEC-Q200 qualification supports use in automotive power electronics and other demanding transport applications.
• Compact footprint for through-hole designs: φ10 × 25 mm can and 5.0 mm lead spacing ease placement in space-constrained power modules and legacy boards.
• Low loss under ripple: tanδ 0.20 at 120 Hz helps minimize heating and energy loss in AC ripple conditions.
• Production-ready availability: Mass production status and RoHS compliance facilitate volume sourcing and regulatory alignment.
