UCA2C221MHD6

The UCA2C221MHD6 is a miniature, radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a 160 V rating. Engineered for high ripple environments, this polarized can-style component targets power supply and ballast applications that require sustained performance at elevated temperatures.

Key value comes from its high rated ripple current, long load-life endurance at 105°C, and compact radial package—making it suitable where high-frequency ripple handling and long-term reliability are priority requirements.

Key Features

• Capacitance and Voltage: 220 µF nominal capacitance with a rated voltage of 160 V and a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• High Ripple Current: Rated ripple current of 1.4 A (105°C, 100 kHz) and 700 mA at 120 Hz, supporting demanding decoupling and filtering duties under AC/ripple load.
• Long Endurance: Load-life specification of 12000 hours at +105°C when subjected to D.C. bias plus rated ripple current, with limits on capacitance, tan δ and leakage current after endurance testing.
• Dielectric Loss: Tangent of loss angle (tan δ) max 0.15 at 120 Hz and 20°C for the 160 V rating, useful for assessing heating and ESR-related behavior.
• Leakage Current: Measured leakage current of 1508 µA after 1 minute’s application of rated voltage at 20°C; datasheet also specifies the standard leakage-current limit formula (0.04CV + 100 µA).
• Operating Range & Package: Operating temperature −25°C to +105°C; radial lead, can-style package with case dimensions L: 2.5 × D: 1.8 cm and lead spacing of 7.5 mm. Polarized for correct electrolytic use.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies: Bulk and output filtering where high ripple current capability and long life at elevated temperature improve reliability.
• Ballasts and Lamp Drivers: AC ripple and high-frequency loading in ballast circuits benefit from the capacitor’s rated ripple performance.
• General Purpose Power Conditioning: Decoupling and smoothing in industrial and electronic equipment requiring a compact radial-lead solution.

Unique Advantages

• High ripple endurance: 1.4 A rated ripple at 100 kHz and 105°C enables effective handling of high-frequency and high-current ripple without rapid degradation.
• Long operational life: 12000-hour endurance at 105°C provides predictable lifetime behavior for sustained high-temperature operation.
• Compact radial package: Small can dimensions (2.5 × 1.8 cm) and 7.5 mm lead spacing allow integration into space-constrained boards while preserving performance.
• Measurable loss characteristics: Specified tan δ (0.15 at 120 Hz, 20°C) supports thermal and ESR budgeting in power-stage design.
• Clear leakage specification: Documented leakage behavior (1508 µA measured, and datasheet formula 0.04CV+100 µA) simplifies acceptance criteria and quality checks.
• Regulatory alignment: RoHS compliance supports deployments where restricted-substance conformity is required.

Why Choose UCA2C221MHD6?

The UCA2C221MHD6 is positioned for designs that need a compact, polarized aluminum electrolytic capacitor capable of handling substantial ripple currents and prolonged thermal stress. Its combination of 160 V rating, 220 µF capacitance, and 12000-hour endurance at 105°C delivers a balance of energy storage and durability for power conditioning and ballast applications.

Engineers specifying this component gain the ability to predict in-service behavior using the published tan δ, leakage, and ripple ratings, and to integrate a small-form-factor radial can where board space and high-frequency ripple handling are critical.
