UCY2D221MHD6

The UCY2D221MHD6 from Nichicon is a radial-lead aluminum electrolytic capacitor in the UCY series, offering 220 µF capacitance at a 200 V rated voltage. It combines a compact can-style radial package (φ12.5 × 40 mm) with specifications optimized for high ripple currents and long operational life.

Designed for power electronics and industrial use, this part is suited to applications that require sustained performance at elevated temperatures, including automotive-grade designs thanks to its AEC-Q200 qualification.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, providing bulk energy storage and DC filtering for mid- to high-voltage circuits.
• High ripple-current capability: Rated for 1.09 A ripple at 120 Hz (low frequency) and 2.18 A at 100 kHz (high frequency), supporting demanding power-supply and ballast ripple conditions.
• Long endurance at elevated temperature: Rated life of 12,000 hours at +105°C under DC bias plus rated ripple current, enabling extended service in high-temperature environments.
• Reliability & qualification: AEC-Q200 qualified and produced as part of Nichicon’s UCY series, suitable for designs that require recognized reliability standards.
• Thermal and electrical stability: Operates across −40°C to +105°C; low loss tangent (tan δ = 0.20 at 20°C, 120 Hz) for controlled dissipation.
• Radial-lead package: φ12.5 mm diameter, 40 mm length can with 5.0 mm lead spacing (±0.5 mm lead-spacing tolerance) for through-hole mounting and secure mechanical retention.
• Leakage current: Specified leakage current of 1860 μA, consistent with performance expectations for this capacitance and voltage class.
• Regulatory & packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing to suit production and assembly workflows. Mass production status ensures ongoing availability.

Typical Applications

• Power supplies: Bulk filtering and smoothing in power conversion circuits where 200 V rating and high ripple capability are required.
• Ballasts and lighting power modules: Handling ripple and thermal stress in ballast applications as indicated in UCY series documentation.
• Automotive electronics: Energy buffering and decoupling in automotive subsystems, leveraging the part’s AEC-Q200 qualification and extended high-temperature endurance.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low and high frequencies let designers manage AC stress across a wide frequency range without oversizing the capacitor.
• Extended operational life at 105°C: 12,000-hour endurance rating reduces maintenance and replacement cycles in hot-running equipment.
• AEC-Q200 qualified: Provides an established reliability baseline for automotive and other demanding applications.
• Compact radial form factor: φ12.5 × 40 mm can with 5 mm lead spacing delivers considerable capacitance in a through-hole package for robust mounting.
• Measured dissipation and leakage: Low tan δ (0.20 at 120 Hz, 20°C) and specified leakage current allow predictable thermal and power-loss budgeting in designs.
• RoHS compliant and production-ready: Environmentally compliant and available in bulk or bag packaging to support manufacturing needs.
