UCY2D221MHD3

The UCY2D221MHD3 is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can package. It provides 220 µF capacitance at a 200 V rating with a compact φ18 × 25 L footprint and 7.5 mm lead spacing.

Designed for applications that require sustained ripple handling and long operational life, this AEC-Q200 qualified, RoHS-compliant part delivers high ripple current capability and extended endurance up to 12,000 hours at 105°C, making it suitable for demanding power circuits and industrial or automotive systems.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 200 V and tolerance of -20% to +20%.
• High Ripple Current — Low-frequency ripple current 1.185 A (120 Hz) and high-frequency ripple current 2.37 A (100 kHz), supporting high-demand smoothing and filtering.
• Long Endurance — Rated life of 12,000 hours at 105°C under DC bias plus rated ripple current for reliable long-term operation.
• Wide Temperature Range — Operates from -40°C to +105°C to support a broad set of environments.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) 0.2 (20°C, 120 Hz) and specified leakage current of 1,860 µA.
• Radial Lead Can — φ18 × 25 L metal can with 7.5 mm lead spacing (lead spacing tolerance 0.5 mm); available in bulk (no terminal forming) or bag packing.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for regulated markets.

Typical Applications

• Automotive power electronics — AEC-Q200 qualification and high ripple capability make this part suitable for smoothing and bulk energy storage in automotive power systems.
• Power supplies and converters — Use for bulk filtering and ripple suppression where a 200 V rating and high ripple current are required.
• Ballasts and lighting drivers — Suited for ballast applications that demand sustained ripple handling and thermal endurance.
• High-ripple industrial circuits — Applicable to industrial power circuits and controllers that require compact, long-life capacitors for energy buffering.

Unique Advantages

• High ripple-handling capability: Measured low-frequency ripple current of 1.185 A (120 Hz) and high-frequency ripple current of 2.37 A (100 kHz) reduce stress on downstream circuitry.
• Extended operational life: 12,000-hour endurance at 105°C supports long maintenance intervals and predictable lifecycle planning.
• Compact radial-lead package: φ18 × 25 L can with 7.5 mm lead spacing provides a small footprint for constrained board layouts.
• Defined electrical performance: tan δ = 0.2 (20°C, 120 Hz) and specified leakage current of 1,860 µA give clear, verifiable loss and leakage characteristics for design calculations.
• Automotive-grade qualification and compliance: AEC-Q200 qualification plus RoHS compliance help meet regulated industry requirements.
• Flexible packing options: Available in bulk (no terminal forming) or bag packing to support different assembly and procurement workflows.
