UCY2C221MHD9

The UCY2C221MHD9 is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for demanding power applications. It delivers 220 µF capacitance at a 160 V rating with a compact φ12.5 × 35.5 mm package and 5 mm lead spacing for through-hole mounting.

Engineered for long life and high ripple handling, this AEC-Q200 qualified component is targeted at automotive-grade and industrial power systems, including power supplies and ballast applications, where sustained performance at elevated temperatures is required.

Key Features

• Capacitance & Tolerance — 220 µF nominal with ±20% tolerance at 120 Hz, 20 °C for predictable energy storage and decoupling.
• Rated Voltage — 160 V working voltage suitable for higher-voltage DC systems.
• High Ripple Current Capability — Low-frequency ripple current of 1.05 A (120 Hz) and high-frequency ripple current of 2.10 A (100 kHz) to support heavy filtering and smoothing loads.
• Long Endurance — Rated life of 12,000 hours at 105 °C under specified load conditions, providing sustained reliability in elevated-temperature environments.
• Temperature Range — Operates from −40 °C to +105 °C for broad environmental tolerance.
• Loss Characteristic — tan δ (loss tangent) 0.20 measured at 20 °C, 120 Hz for predictable dissipation characteristics.
• Leakage Current — Specified leakage current 1,508 µA; general datasheet leakage formula: I ≤ 0.04CV + 100 µA after 1 minute at 20 °C.
• Package & Mounting — Radial-lead can, size φ12.5 × 35.5L with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant to meet industry reliability and environmental requirements.

Typical Applications

• Automotive Electronics — Bulk energy storage, smoothing and filtering in automotive power subsystems where AEC-Q200 qualification and long life at 105 °C are required.
• Power Supplies — Input/output filtering and bulk capacitance in DC power supplies and converters that require high ripple-handling capability.
• Ballasts — Designed for ballast applications specified in the product series documentation for reliable operation under continuous load.

Unique Advantages

• High ripple tolerance: Defined ripple currents at both low (1.05 A at 120 Hz) and high (2.10 A at 100 kHz) frequencies enable effective filtering across a wide frequency range.
• Extended operational life: 12,000-hour endurance at 105 °C supports long-term reliability in thermally stressed environments.
• AEC-Q200 qualified: Provides a level of component qualification useful for designs targeting automotive-level reliability and testing.
• Compact radial package: φ12.5 × 35.5 mm can with 5 mm lead spacing facilitates space-efficient through-hole layouts and robust mechanical mounting.
• Predictable electrical loss: Specified tan δ = 0.20 (120 Hz, 20 °C) helps designers estimate dissipation and heating under load.
• Regulatory compliance: RoHS compliant to support environmentally constrained product builds.
