UCY2W180MHD6

The UCY2W180MHD6 is a miniature, radial-lead aluminum electrolytic capacitor designed for high-reliability power applications. It pairs a 18 µF capacitance with a 450 V rated voltage in a compact φ12.5 × 20 mm can and is optimized for applications that demand high ripple handling and long life at elevated temperatures.

Manufactured by Nichicon as part of the UCY series, this polarized capacitor is targeted at automotive and power-electronics uses where sustained performance, endurance, and compliance are required.

Key Features

• Rated Capacitance and Voltage — 18 µF nominal capacitance at a rated voltage of 450 V, with capacitance tolerance of −20% to +20%.
• High Ripple Current Capability — Low-frequency ripple current 255 mA at 120 Hz and high-frequency ripple current 510 mA at 100 kHz, supporting demanding power supply ripple conditions.
• Low Loss (tan δ) — Tangent of loss angle (tan δ) specified at 0.24 (measured at 20°C, 120 Hz), indicating controlled dissipation for high-voltage operation.
• Long Life at Elevated Temperature — Rated endurance of 10,000 hours at 105°C under DC bias plus rated ripple current, providing extended service life in harsh thermal environments.
• Compact Radial Package — φ12.5 mm diameter × 20 mm length can with radial lead spacing of 5.0 mm (lead spacing tolerance ±0.5 mm), suitable for through-hole mounting and tight PCB layouts.
• Leakage Current — Specified leakage current of 424 µA (measured condition per product data), consistent with high-voltage electrolytic requirements.
• AEC-Q200 Qualified & RoHS Compliant — AEC-Q200 rating and RoHS compliance make the part suitable for regulated, high-reliability applications.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing for flexible inventory and assembly handling.

Typical Applications

• Automotive Power Electronics — Energy smoothing and ripple filtering in automotive power modules where AEC-Q200 qualification and high-temperature endurance are required.
• Power Supplies and DC Front-Ends — Bulk and filter capacitance in power supplies and converters that demand high ripple current capability and 450 V rating.
• Ballast and Lighting Electronics — Designed for ballast and related lighting power circuits where high ripple and extended operating life at elevated temperatures are beneficial.

Unique Advantages

• High-voltage, compact form factor: 450 V rating in a φ12.5 × 20 mm can reduces board footprint while meeting high-voltage system needs.
• High ripple-handling capability: Separate specifications for low- and high-frequency ripple current (255 mA at 120 Hz; 510 mA at 100 kHz) allow confident selection for diverse switching and line-frequency environments.
• Long endurance at 105°C: 10,000-hour rated life under DC bias and ripple current supports designs meant for prolonged high-temperature operation.
• Automotive-grade reliability: AEC-Q200 qualification supports use in regulated automotive and similarly demanding applications.
• Through-hole radial package for robust assembly: 5.0 mm lead spacing and radial lead form simplify insertion and mechanical retention in through-hole boards and power modules.
• Regulatory compliance: RoHS compliance ensures alignment with lead-free and restricted-substance requirements.
