UCYW6180MPD

The UCYW6180MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series designed for high-reliability power applications. It delivers 18 µF capacitance at a 420 V rating in a compact φ10 × 30.5 mm can with 5 mm lead spacing.

Built for sustained operation under stress, this polarized capacitor is specified for -40°C to 105°C operation and a rated load life of 12000 hours at 105°C, making it suitable for high-voltage filtering and energy smoothing in demanding systems.

Key Features

• Capacitance & Voltage — 18 µF nominal capacitance with a rated voltage of 420 V and tolerance of -20% to +20%.
• High Ripple Current Capability — Low-frequency ripple current of 215 mA (120 Hz) and high-frequency ripple current of 430 mA (100 kHz) for effective AC filtering and decoupling across frequencies.
• Long Life at Elevated Temperature — Rated endurance of 12000 hours at +105°C under DC bias plus rated ripple current, supporting extended field life in hot environments.
• Electrical Loss and Leakage — Dissipation factor (tan δ) of 0.24 (measured at 20°C, 120 Hz) and measured leakage current of 402.4 µA, allowing predictable loss and self-discharge behavior.
• Compact Radial Lead Package — φ10 mm diameter by 30.5 mm length can, radial lead mounting with 5 mm lead spacing and lead spacing tolerance ±0.5 mm for through-hole assembly.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for regulated design environments.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production handling preferences; product is in mass production.

Typical Applications

• Switch‑mode Power Supplies — High voltage rating and robust ripple current ratings make this capacitor suitable for input/output filtering and energy buffering in SMPS designs.
• Ballasts and LED Drivers — The 420 V rating and high-frequency ripple capability support AC/DC conversion and smoothing in lighting power circuits.
• Automotive Electronics — AEC‑Q200 qualification and -40°C to +105°C operating range support use in automotive power modules and control electronics that require high-voltage filtering.
• Industrial Power Control — Long endurance at elevated temperature and reliable leakage characteristics suit motor drives, inverters, and other industrial high-voltage power systems.

Unique Advantages

• High DC Voltage Handling: 420 V rating enables direct use in higher-voltage rails without series stacking or additional components.
• Designed for Long Field Life: 12000-hour endurance at 105°C provides predictable lifecycle performance in thermally demanding applications.
• Broad Frequency Ripple Support: Specified ripple currents at both low and high frequencies (215 mA at 120 Hz, 430 mA at 100 kHz) help maintain performance across switching and line-frequency scenarios.
• Automotive-Grade Qualification: AEC‑Q200 qualification supports deployment in regulated automotive systems requiring component-level qualification.
• Compact Through-Hole Form Factor: φ10 × 30.5 mm radial can with 5 mm lead spacing simplifies board layout for compact power modules and retrofit designs.
• Regulatory Compliance: RoHS compliance supports use in designs targeting regulated markets and environmental requirements.
