UCX1E222MNS1MS

The UCX1E222MNS1MS is a chip-type aluminum electrolytic capacitor from Nichicon's UCX series designed for high-reliability, high-temperature surface-mount applications. It delivers 2200 µF capacitance at a 25 V rating with low-temperature ESR characterization and AEC-Q200 qualification.

Targeted at demanding power-electronics environments, this SMD can supports high ripple currents and extended endurance up to 135°C, making it suited to automotive and industrial power subsystems that require robust decoupling, buffering and energy-hold capabilities.

Key Features

• Core Electrical Performance — 2200 µF (2.2 mF) capacitance with ±20% tolerance and 25 V rated voltage for bulk energy storage and smoothing.
• Low ESR and High Ripple Capability — ESR of 50 mΩ (measured at 20°C/100 kHz) with low-frequency ripple current rated 700 mA (120 Hz) and high-frequency ripple current 1.4 A (10 kHz) for effective ripple filtering in power converters.
• Dissipation and Loss — tanδ (DF) = 0.2 measured at 20°C, 120 Hz, providing a clear specification for AC loss and thermal planning; specified leakage current 550 µA.
• High-Temperature Endurance — Rated operating temperature −40°C to +135°C with life/endurance specified for 2000 hours at 135°C, supporting sustained operation in elevated-temperature environments.
• Automotive-Grade Reliability — AEC-Q200 qualification and vibration-resistant construction align the part for automotive and other high-reliability applications.
• Surface-Mount, Carrier-Tape Packaging — Chip-type SMD can (φ18 × 16.5 L) supplied in embossed carrier taping for automated placement and volume production.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive power systems — AEC-Q200 qualification and −40°C to +135°C range make this capacitor suitable for under-hood and vehicle electronics requiring reliable bulk capacitance and ripple handling.
• DC–DC converters and power supplies — Low ESR and rated ripple currents support output filtering and stabilization in switching regulators and power modules.
• Backup/hold-up energy storage — 2200 µF capacitance provides capacitance for short-term energy buffering and transient hold-up in electronic subsystems.
• Industrial electronics — High-temperature endurance and vibration resistance match industrial drives, controllers, and power distribution modules operating in harsh environments.

Unique Advantages

• High-temperature reliability: Specified for continuous operation to 135°C with a 2000-hour endurance rating, helping designs tolerate elevated ambient and thermal stress.
• Measurable low-temperature ESR: ESR specified at 20°C/100 kHz and low-temperature ESR considerations provided, enabling predictable performance across temperature extremes.
• Strong ripple handling: Distinct low- and high-frequency ripple ratings (700 mA at 120 Hz and 1.4 A at 10 kHz) let engineers size the part for both switching and line-frequency ripple environments.
• Automotive-ready qualification: AEC-Q200 rating supports use in applications with rigorous reliability requirements and qualification processes.
• Surface-mount automation: Embossed carrier tape packaging and chip can form factor simplify automated placement and high-volume assembly.
• Clear electrical limits: Specified tanδ and leakage current values aid accurate thermal and leakage budgeting in system designs.
