UCY2D121MHD6

The UCY2D121MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can package. It delivers 120 µF capacitance at 200 V with a compact φ12.5 × 30.5 mm profile and 5 mm lead spacing, designed for applications that require elevated ripple handling and long life under high temperature.

Targeted for power supply and ballast uses, this radial lead capacitor combines high ripple current capability, long endurance at 105°C, and AEC-Q200 qualification for demanding environments.

Key Features

• Capacitance and Voltage — 120 µF nominal capacitance with a rated voltage of 200 V and tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 810 mA at 120 Hz and high-frequency ripple current of 1.62 A at 100 kHz for improved performance in switching and high-frequency supplies.
• Long Endurance — Rated for 12,000 hours at +105°C under rated DC bias plus ripple current, supporting extended field life in high-temperature systems.
• Electrical Losses — Low dissipation factor with tan δ = 0.20 measured at 20°C, 120 Hz, helping maintain efficiency in power circuits.
• Leakage Current — Specified leakage current of 1,060 µA, measurable after rated-voltage application at 20°C.
• Mechanical and Mounting — Radial lead can package (φ12.5 mm diameter, 30.5 mm length) with 5 mm lead spacing; offered in bulk or bag packing (no terminal forming).
• Qualification and Compliance — AEC-Q200 qualified and RoHS compliant for regulated and safety-conscious designs.
• Temperature Range — Operating range from −40°C to +105°C for use across a broad thermal envelope.

Typical Applications

• Power Supplies — Provides smoothing and bulk energy storage in DC power modules and board-level converters where high ripple handling and long life are required.
• Ballasts and Lighting — Suited for ballast applications that demand stable capacitance and reliable ripple performance at elevated temperatures.
• Automotive Electronics — AEC-Q200 qualification makes it appropriate for automotive power and control modules that require durable electrolytic bulk capacitance.
• Industrial Power Control — Useful in motor drives, inverters, and other industrial power systems needing compact, high-ripple capacitors rated for continuous operation at 105°C.

Unique Advantages

• High ripple capability: Combines 810 mA (120 Hz) and 1.62 A (100 kHz) ripple ratings to support both low- and high-frequency power stages.
• Extended high-temperature life: 12,000-hour endurance at +105°C reduces maintenance and replacement cycles in thermally stressed systems.
• Automotive-grade qualification: AEC-Q200 designation provides documented reliability for regulated automotive and similar applications.
• Compact radial form factor: φ12.5 × 30.5 mm can package with 5 mm lead spacing saves board space while delivering substantial capacitance and voltage rating.
• Measured loss and leakage specs: tan δ = 0.20 and leakage current = 1,060 µA provide quantifiable parameters for power-loss and standby-current budgets.
• Standards compliance: RoHS compliance supports regulatory requirements for environmental and material controls.
