UCY2E181MHD6

The UCY2E181MHD6 from Nichicon is a miniature, radial-lead aluminum electrolytic capacitor in the UCY series designed for high ripple current and long-life applications. It is a polarized, can-style capacitor rated at 250 V with 180 µF capacitance and is suited for power supply and ballast use in demanding environments.

Built for robust operation, the part supports extended load life at elevated temperature and meets AEC-Q200 qualification and RoHS requirements, making it appropriate for automotive and other reliability-focused applications.

Key Features

• Capacitance & Voltage — 180 µF capacitance rated for 250 V DC, with ±20% tolerance at 120 Hz, 20°C.
• High ripple current — Rated ripple current of 1.05 A at 120 Hz and 2.1 A at 100 kHz, with a frequency coefficient up to 2.00 at 100 kHz (series datasheet values) to support high-frequency ripple environments.
• Long operating life — Designed for extended load life at elevated temperature, with a specified endurance of 10000 to 12000 hours at +105°C under rated conditions.
• Temperature range — Operating temperature range from −40°C to +105°C for broad environmental tolerance.
• Leakage current specification — Leakage current after 1 minute at 20°C does not exceed 0.04CV + 100 µA (per series datasheet formula).
• Packaging & mounting — Radial lead, can-style package with lead spacing 7.5 mm and physical dimensions L: 2.5 × D: 1.8 cm for compact board-level implementation.
• Industry compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU) 2015/863), supporting regulated and automotive applications.

Typical Applications

• Power supplies — Bulk or smoothing capacitor in power supply rails where high ripple current capability and long life at elevated temperature are required.
• Ballasts and lighting electronics — Filtering and energy storage in ballast circuits that experience substantial ripple and thermal stress.
• Automotive electronic modules — Decoupling and energy smoothing in automotive control units and power electronics that require AEC-Q200 qualified components.

Unique Advantages

• High ripple handling — Measured ripple current ratings at both low and high frequencies reduce the need for parallel components in ripple-intensive designs.
• Extended elevated-temperature life — Specified endurance at +105°C for 10000–12000 hours provides predictable long-term performance in hot environments.
• Automotive-grade qualification — AEC-Q200 qualification supports use in reliability-focused and regulated applications.
• Compact radial package — Small footprint (2.5 × 1.8 cm) with 7.5 mm lead spacing enables space-efficient board layouts while retaining high capacitance and voltage rating.
• RoHS compliance — Conforms to RoHS directives for use in regulated supply chains.
