UCZ1E222MNJ1MS

The UCZ1E222MNJ1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation up to 125°C. It is a surface-mount, radial can (SMD) part optimized for automotive environments and automatic placement with carrier tape.

With 2.2 mF capacitance at 25 V, a low ESR specification and an AEC-Q200 rating, this capacitor is intended for power filtering, smoothing and decoupling tasks where elevated temperature tolerance and long-term reliability are required.

Key Features

• Capacitance & Voltage — 2.2 mF rated capacitance at 25 V with tolerance of -20% to +20% for predictable bulk energy storage and decoupling.
• High-temperature specification — Rated for operation from -40°C to +125°C, with a specified 3,500-hour lifetime at 125°C to support sustained high-temperature use.
• Low ESR and ripple handling — ESR specified at 45 mΩ (measured at 100 kHz) with ripple current ratings of 1.3 A at 120 Hz and 2.6 A at 10 kHz to reduce heat rise and improve power-stage stability.
• Automotive qualification — AEC-Q200 qualified, supporting deployment in automotive electronic modules that require component-level reliability verification.
• Surface-mount, tape-fed package — Radial can SMD package compatible with automatic mounting machines fed by carrier tape; nominal dimensions L: 1.65 cm × D: 1.8 cm and recommended land size 1.83 × 1.83 cm for PCB layout.
• Polarized aluminum electrolytic — Polarized device with standard leakage characteristics per series datasheet (leakage ≤ 0.01CV μA after 2 minutes at 20°C), suitable for DC power circuits.
• Regulatory compliance — RoHS compliant to 2011/65/EU and (EU)2015/863.

Typical Applications

• Automotive power electronics — Bulk filtering and DC-link smoothing in engine control units, power distribution modules and other vehicle electronic control units where AEC-Q200 qualification and high-temperature operation are required.
• Inverter and motor-drive support — Energy buffering and ripple suppression in motor-drive and power-conversion stages, leveraging the 2.2 mF capacitance, low ESR, and high-frequency ripple rating.
• Sensor and ECU power rails — Decoupling and local energy storage for sensors, ADAS modules and ECUs that must operate reliably across -40°C to +125°C.

Unique Advantages

• High-temperature endurance: Specified 3,500 hours at 125°C provides measurable long-term performance for designs exposed to sustained elevated temperatures.
• Automotive-grade reliability: AEC-Q200 qualification signals component-level suitability for vehicle electronics and established reliability screening.
• Low ESR for improved power performance: 45 mΩ ESR at 100 kHz and rated ripple currents reduce internal heating and help maintain stable voltage under dynamic load.
• Surface-mount and tape-feed compatible: Radial can SMD form factor and carrier-tape compatibility streamline automated PCB assembly for production environments.
• Clear thermal range and testability: Specified stability from -40°C to +125°C with an added ESR specification after -40°C testing supports validated low-temperature and high-temperature behavior.
• RoHS compliant: Meets current RoHS directives for environmental and regulatory consistency across projects.
