UCX1E222MNJ1MS

The UCX1E222MNJ1MS is a chip‑type aluminum electrolytic capacitor designed for surface‑mount assemblies that require reliable operation across a wide temperature range. With a rated capacitance of 2.2 mF at 25 V and AEC‑Q200 qualification, it targets demanding applications where high temperature endurance and controlled ESR are required.

Engineered for automated assembly, this part includes an ESR specification measured after −40°C testing and supports high ripple currents for power filtering and decoupling in thermally stressed environments.

Key Features

• Capacitance & Voltage — 2.2 mF rated capacitance at 25 V for energy storage and bulk decoupling in power domains.
• Wide Temperature Range — Specified operation from −40°C to +135°C, enabling use in hot environments and temperature‑extreme applications.
• Low‑temperature ESR Characterization — ESR specification added after −40°C testing to ensure predictable impedance behavior at low temperatures.
• Electrical Performance — Equivalent series resistance of 50 mΩ measured at 100 kHz; ripple current ratings of 700 mA at 120 Hz and 1.4 A at 10 kHz for handling AC stress.
• High‑Temperature Endurance — Rated for 2000 hours of endurance at 135°C under rated voltage, with defined limits for capacitance change, tan δ, and leakage current after the endurance test.
• Surface‑Mount Packaging — Chip‑type radial can SMD suitable for automatic mounting machines fed with carrier tape; compact size L: 1.65 × D: 1.8 cm with surface mount land size L: 1.83 × W: 1.83 cm.
• Compliance & Qualification — AEC‑Q200 qualified and RoHS compliant (2011/65/EU,(EU)2015/863) for regulated markets and reliability‑focused designs.
• Polarized Design — Polarized aluminum electrolytic construction for standard DC bulk energy and filtering roles.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and −40°C to +135°C rating make it suitable for control modules and power electronics where temperature resilience and validated reliability are required.
• Power Supply Filtering — 2.2 mF capacitance, low ESR (50 mΩ at 100 kHz), and specified ripple currents support bulk smoothing and decoupling in DC‑DC converters and power rails.
• High‑Temperature Electronic Modules — Long endurance at 135°C and surface‑mount compatibility enable use in compact assemblies exposed to sustained elevated temperatures.

Unique Advantages

• Defined Low‑Temperature Behavior: ESR specification after −40°C testing provides designers with verifiable impedance data for cold‑start and low‑temperature performance.
• High‑Temperature Endurance: 2000 hours at 135°C under rated voltage offers measurable longevity for thermal stress applications.
• Automated Assembly Ready: Carrier‑tape compatibility and chip‑type SMD packaging simplify high‑volume PCB assembly and reduce handling steps.
• Robust Ripple Handling: Dual ripple current ratings (700 mA at 120 Hz, 1.4 A at 10 kHz) allow selection based on the frequency content of the application’s load.
• Industry Qualification & Compliance: AEC‑Q200 qualification and RoHS compliance support regulated product development and procurement requirements.
• Compact Footprint: Small L × D size (1.65 × 1.8 cm) and defined land pattern facilitate space‑constrained designs without sacrificing capacitance.
