UUE1E221MNS1GS

The UUE1E221MNS1GS is a surface-mount aluminum electrolytic chip capacitor from Nichicon’s UUE series, rated 220 µF at 25 V. Designed for demanding environments, it combines high capacitance in a compact SMD radial/can package and is targeted at heavy-duty automotive and high-temperature electronic designs.

Key value comes from its high-temperature endurance and automotive qualification: the UUE series specifies a 5000-hour load life at 125°C and AEC-Q200 qualification, delivering measurable reliability for temperature-stressed power rails and systems operating between −40°C and 125°C.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 25 V and ±20% tolerance for bulk energy storage and decoupling on moderate-voltage rails.
• High-Temperature Endurance — Series load life specified at 5000 hours at 125°C; endurance tests specify capacitance change within ±30% and leakage current within initial limits after the life test.
• Automotive-Grade Reliability — AEC-Q200 qualified and explicitly noted as suited for automobile electronics where heavy-duty service is required.
• Wide Operating Range — Rated for operation from −40°C to 125°C, supporting electronics exposed to wide temperature swings.
• Ripple Current Performance — Rated ripple currents include 127.3 mA at 120 Hz and 190 mA at 10 kHz, with frequency coefficients defined across common ranges for accurate thermal and ripple planning.
• Compact Surface-Mount Package — Chip-type radial/can SMD package with overall dimensions of approximately 1 cm × 1 cm and a recommended PCB land size of 1.03 cm × 1.03 cm for board-level integration.
• Low Leakage — Leakage current limit given by datasheet formula: after 1 minute at rated voltage (20°C), leakage current is ≤ 0.03CV (µA), enabling predictable bias behavior in designs.

Typical Applications

• Automotive Electronics — Suited for in-vehicle modules and electronic control units where AEC-Q200 qualification and long high-temperature load life are required.
• Power Supply Decoupling — 220 µF at 25 V with defined ripple current figures supports smoothing and decoupling on local power rails in temperature-stressed environments.
• Industrial Control Electronics — Compact SMD can package and −40°C to 125°C rating make it appropriate for control boards exposed to elevated ambient temperatures.
• Telematics and Sensor Modules — Stable operation across broad temperatures and controlled leakage make it suitable for roadside telematics and sensor front-ends operating in harsh conditions.

Unique Advantages

• AEC-Q200 Qualification: Provides documented automotive-grade qualification for designs that require standardized reliability testing and traceability.
• Designed for High-Temperature Operation: Series load life specified at 5000 hours at 125°C and an operating range to 125°C reduces risk in thermally demanding assemblies.
• Measured Ripple Characteristics: Published ripple current values (127.3 mA at 120 Hz, 190 mA at 10 kHz) help predict heating and lifetime in real operating conditions.
• Compact SMD Can Format: 1 cm × 1 cm footprint and surface-mount radial can construction simplify placement on high-density PCBs while providing high capacitance density.
• Predictable Leakage Behavior: Leakage current specification (≤ 0.03CV µA after 1 minute at 20°C) allows accurate bias budgeting for low-current circuits.
