UCL1E221MCL6GS

The UCL1E221MCL6GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount can package designed for automated carrier-tape mounting. Built for demanding environments, it delivers 220 µF at a 25 V rating with polarization and ±20% capacitance tolerance.

This capacitor is AEC-Q200 qualified and RoHS compliant, offering a wide operating temperature range from −55°C to +105°C and an endurance rating of 2000 hours at 105°C, making it suitable for automotive and other robust embedded power applications.

Key Features

• Electrical Performance — 220 µF nominal capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low Impedance — Rated impedance of 100 mΩ to support low-loss filtering and decoupling in power circuits.
• Ripple Current Capability — Handles 425 mA at 120 Hz and 850 mA at 10 kHz for AC ripple and switching applications.
• Thermal & Lifetime — Operating temperature range −55°C to +105°C with a specified lifetime of 2000 hours at 105°C.
• Reliability & Qualification — AEC-Q200 qualified for automotive-grade reliability; meets endurance requirements with capacitance change within ±30% after rated life testing.
• Leakage & Loss Characteristics — Leakage current specification: after 2 minutes at rated voltage and 20°C, I ≤ 0.01CV or 3 µA (whichever is greater); tan δ specified by rated voltage per datasheet.
• Compact SMD Can Package — Radial, can-style surface-mount package designed for carrier-tape automated placement; package footprint L: 1.03 cm × W: 1.03 cm and component size approximately L: 0.77 cm × D: 1.00 cm.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Bulk smoothing and decoupling in ECUs, power modules and other automotive systems where AEC-Q200 qualification and elevated-temperature endurance are required.
• DC–DC Converters & Power Management — Output filtering and energy storage for switching regulators that require high ripple-current handling and low impedance.
• Embedded & Industrial Control — Supply decoupling and transient suppression in compact, board-level power networks operating across wide temperature ranges.

Unique Advantages

• AEC-Q200 Qualification: Provides an established automotive reliability baseline for designs requiring recognized component-level qualification.
• Low Impedance (100 mΩ): Minimizes voltage ripple and power loss in filtering and decoupling roles, improving regulator stability and efficiency.
• High Ripple Capability: Specified ripple currents at both low (425 mA @120 Hz) and high (850 mA @10 kHz) frequencies for use with switching supplies.
• Wide Temperature Range & Long Life: Rated −55°C to +105°C with 2000 hours endurance at 105°C to support long-term operation in high-temperature environments.
• SMD Can Designed for Automation: Carrier-tape compatible surface-mount can package simplifies assembly for high-volume PCB manufacturing.
• Controlled Leakage & Loss: Leakage current limited to 0.01CV or 3 µA after application of rated voltage (2 minutes at 20°C), with tan δ limits defined by rated voltage.
