UCZ1E222MNQ1MS

The UCZ1E222MNQ1MS is a chip-type aluminum electrolytic capacitor designed for high-reliability applications. It provides 2.2 mF capacitance at a 25 V rating in a compact surface-mount radial can format.

Engineered for extended high-temperature operation (−40°C to +125°C) with AEC-Q200 qualification and RoHS compliance, this capacitor targets automotive and other demanding power applications that require low ESR, defined ripple handling, and automated assembly compatibility.

Key Features

• Electrical Performance — 2.2 mF capacitance with ±20% tolerance and a 25 V rated voltage, delivering bulk energy storage for power rails and smoothing applications.
• Low ESR — 45 mΩ equivalent series resistance measured at 100 kHz, with a low-temperature ESR specification verified after −40°C testing to maintain performance across the full temperature range.
• High-Temperature Endurance — Specified for continuous operation up to +125°C with a rated lifetime of 3500 hours at 125°C, supporting long-term operation in hot environments.
• Ripple Current Capability — Rated ripple currents of 1.3 A at 120 Hz and 2.6 A at 10 kHz, suitable for smoothing and decoupling in switching power supplies and converters.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant, addressing quality and environmental requirements for regulated industries.
• Surface-Mount, Assembly-Ready Package — Chip-type radial can SMD intended for automatic mounting with carrier tape; compact footprint with dimensions L: 1.65 × D: 1.8 cm and recommended land size L: 1.83 × W: 1.83 cm.
• Polarized Design — Polarized electrolytic construction for DC bulk capacitance applications.

Typical Applications

• Automotive Power Electronics — Bulk smoothing and decoupling on automotive power rails where AEC-Q200 qualification and +125°C endurance are required.
• DC–DC Converter Output Filtering — Provides low ESR bulk capacitance and defined ripple current handling for switching regulators and power converters.
• Infotainment and Control Modules — Energy storage and supply stabilization for onboard electronic modules operating over wide temperature ranges.
• Industrial Power Systems — High-temperature-capable bulk capacitor for industrial converters and controllers exposed to elevated ambient temperatures.

Unique Advantages

• High-temperature reliability: Rated for operation to +125°C with a 3500-hour lifetime at that temperature, enabling sustained performance in hot environments.
• Low-temperature ESR verification: ESR performance is specified after −40°C testing, giving predictable behavior across the full −40°C to +125°C range.
• Measured high-frequency performance: 45 mΩ ESR at 100 kHz and a 2.6 A rating at 10 kHz make the part suitable for high-frequency ripple damping in switching supplies.
• Automotive-grade qualification: AEC-Q200 rating supports use in regulated automotive electronics and systems.
• Assembly-friendly package: Surface-mount radial can design compatible with automatic mounting using carrier tape and a compact PCB land pattern for space-constrained designs.
• Regulatory compliance: RoHS compliance simplifies use in designs subject to environmental directives.
