UCY2C221MHD

The UCY2C221MHD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UCY series engineered for high ripple current and long operational life. It delivers 220 µF capacitance at a 160 V rating in a compact φ12.5 × 40 mm can, optimized for power‑handling applications.

Designed for demanding environments, the part offers a wide operating temperature range and AEC‑Q200 qualification, making it suitable for industrial and automotive power electronics, power supplies and ballast applications where sustained ripple endurance and reliability are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 160 V and tolerance of −20% to +20% for predictable decoupling and energy storage.
• High ripple current capability — Low‑frequency ripple current 1.2 A at 120 Hz and high‑frequency ripple current 2.4 A at 100 kHz, supporting high‑load, switching and high‑frequency power circuits.
• Long endurance — Rated load life of 12,000 hours at +105 °C, providing extended service life under elevated temperature and bias conditions.
• Electrical loss — tan δ (loss tangent) ≤ 0.20 measured at 20 °C, 120 Hz (rated voltage 160 V), for controlled dissipation in AC and ripple environments.
• Leakage current — Specified leakage current of 1,508 µA (per product data), enabling predictable standby and leakage behavior after application of rated voltage.
• Form factor & mounting — Radial lead, polarized can with φ12.5 mm diameter, 40 mm length and 5.0 mm lead spacing (±0.5 mm), available in bulk or bag packing (no terminal forming).
• Environmental & qualification — RoHS compliant and AEC‑Q200 rated for applications requiring recognized component qualification.

Typical Applications

• Power supplies — Bulk and output filtering in switch‑mode and linear power supplies where high ripple handling and long life are required.
• Ballasts and lighting drivers — Energy storage and ripple smoothing in ballast circuits as noted in the UCY series specification.
• Automotive power systems — Use in vehicle power electronics and modules that benefit from AEC‑Q200 qualification and extended high‑temperature endurance.
• Industrial converters and inverters — Filtering and decoupling for converters that demand high ripple current capability and robust temperature performance.

Unique Advantages

• High ripple endurance: Meets 1.2 A (120 Hz) and 2.4 A (100 kHz) ripple current ratings to support high‑frequency switching loads without compromising life.
• Extended high‑temperature life: 12,000 hours at +105 °C specification reduces maintenance and replacement frequency in hot operating environments.
• Automotive‑grade qualification: AEC‑Q200 rating supports usage in automotive and similarly demanding applications that require qualified components.
• Compact radial package: φ12.5 × 40 mm can and 5 mm lead spacing provide a small footprint for space‑constrained power assemblies while keeping through‑hole mounting simplicity.
• Regulatory compliance: RoHS compliance supports use in regulated markets and designs that require restricted‑substance adherence.
