UCY2C221MHD6

The UCY2C221MHD6 is a miniature radial‑lead aluminum electrolytic capacitor from Nichicon’s UCY series. It provides 220 µF capacitance at a 160 V rating in a compact φ18 × 20 mm can with radial leads and 7.5 mm lead spacing.

Designed for high‑ripple, long‑life applications, this AEC‑Q200 qualified, RoHS‑compliant part is suited for power supply and ballast filtering in demanding systems where elevated temperature endurance and reliable ripple handling are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with ±20% tolerance, rated at 160 V DC for mid‑voltage filtering and energy‑storage tasks.
• High Ripple Current — Low‑frequency ripple current 1.105 A at 120 Hz and high‑frequency ripple current 2.21 A at 100 kHz, enabling effective smoothing under significant AC ripple loads.
• Long Life / Endurance — Rated for 10,000 hours at +105°C under specified endurance conditions, supporting extended service life in elevated temperature environments.
• Thermal Range — Operating temperature range from −40°C to +105°C for broad environmental compatibility.
• Electrical Loss — Tangent of loss angle (tan δ) 0.20 measured at 20°C, 120 Hz, for predictable ESR/DF behavior in designs.
• Leakage Current — Specified leakage current of 1508 µA to support predictable startup and bias conditions.
• Mechanical & Packaging — Radial lead can (φ18 × 20 mm) with 7.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS‑compliant for regulated applications including automotive electronics.

Typical Applications

• Power Supplies — Bulk filtering and ripple smoothing in switching and linear power supplies where high ripple current capability and long life are required.
• Ballasts & Lighting Drivers — Energy storage and AC ripple handling in ballast circuits as noted in UCY series documentation.
• Automotive Electronics — Voltage filtering and decoupling in automotive systems that require AEC‑Q200 qualified components and operation across −40°C to +105°C.
• Industrial Power Modules — DC bus decoupling and transient energy support in industrial power electronics operating at elevated temperatures.

Unique Advantages

• High ripple capability: Specified ripple currents at both low and high frequencies support effective filtering across a range of switching and line conditions.
• Extended high‑temperature life: 10,000‑hour endurance at +105°C provides predictable longevity in thermally stressed designs.
• AEC‑Q200 qualification: Enables use in designs targeting automotive applications with recognized component-level qualification.
• Compact radial can: φ18 × 20 mm packaging delivers a small footprint for high‑voltage, high‑capacitance implementations with through‑hole mounting.
• Predictable electrical behavior: Specified tan δ and leakage current values allow engineering of stable bias and thermal behavior in power circuits.
• RoHS compliant packaging options: Available in bulk or bag packing to match assembly and inventory handling requirements.
