UCX1E222MNQ1MS

The UCX1E222MNQ1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly and high-temperature applications. It delivers 2.2 mF capacitance at a 25 V rating in a compact radial can SMD package intended for automatic mounting with carrier tape.

Engineered for demanding environments, this AEC-Q200 qualified, RoHS-compliant capacitor provides extended endurance at elevated temperatures and measurable ESR and ripple performance targets suitable for power-conditioning and energy-storage roles in harsh conditions.

Key Features

• Capacitance & Voltage — 2.2 mF capacitance rated at 25 V with tolerance of -20% to +20% (±20%).
• High Temperature Rating — Rated for continuous operation from -40°C to +135°C and specified for 2000 hours at 135°C endurance.
• Low-temperature ESR specification — ESR specified after test at -40°C; equivalent series resistance is 50 mΩ at 100 kHz.
• Ripple current capability — 700 mA at 120 Hz and 1.4 A at 10 kHz, enabling effective smoothing and decoupling in power circuits.
• Package & Mounting — Surface-mount, radial can SMD intended for automatic mounting machines fed with carrier tape; surface-mount land size L: 1.83 × W: 1.83 cm, part size L: 1.65 × D: 1.8 cm.
• Reliability & Compliance — AEC-Q200 qualified and RoHS directive (2011/65/EU, (EU)2015/863) compliant; designed for endurance and soldering-heat resistance per datasheet conditions.

Typical Applications

• Automotive power electronics — Energy storage and bulk decoupling in control modules and power-supply rails where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC converters and regulator outputs — Provides bulk capacitance and ripple handling for converters operating across wide temperature ranges.
• Industrial and harsh-environment electronics — Smoothing and decoupling in systems exposed to elevated ambient temperatures and vibration where long-term stability is important.
• On-board backup and hold-up circuits — Short-term energy storage and voltage stabilization where compact SMD packaging and reliable high-temperature performance matter.

Unique Advantages

• High-temperature endurance: Specified for 2000 hours at 135°C, supporting designs that must tolerate sustained elevated temperatures.
• Automotive-grade qualification: AEC-Q200 qualification supports use in automotive and similarly demanding applications that require component-level qualification.
• Measured ESR after low-temperature test: ESR specified following -40°C testing—50 mΩ at 100 kHz—helping designers predict performance across temperature extremes.
• Robust ripple handling: Dual-frequency ripple current ratings (700 mA at 120 Hz, 1.4 A at 10 kHz) simplify selection for both line-frequency and switching-frequency applications.
• SMD compatibility for automated assembly: Designed for carrier-tape feeding and surface-mount placement to support high-throughput manufacturing.
• Regulatory compliance: RoHS compliance aligns with lead-free assembly and regulatory requirements.
