UCK1E292MNS1MS

The UCK1E292MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor from Nichicon’s UCK series designed for surface-mount assembly. It delivers 2.9 mF capacitance at a 25 V rating and is intended for applications that require high-temperature endurance and AEC-Q200 qualification.

With an operating temperature range of -55°C to +105°C, RoHS compliance, tape-feeding compatibility for automated mounting, and a compact radial can SMD package, this capacitor is positioned for demanding electronic modules that need stable bulk capacitance and high ripple-current capability.

Key Features

• Capacitance & Voltage — 2.9 mF rated capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low Impedance Design — Chip-type construction tuned for low impedance performance to support high ripple conditions; rated ripple current is 955 mA at 120 Hz and 1.91 A at 10 kHz.
• High Temperature Endurance — Rated for operation from -55°C to +105°C with an endurance specification of 5000 hours at 105°C.
• AEC-Q200 Qualified — Meets AEC-Q200 qualification for use in automotive electronics where that qualification is required.
• Surface-Mount, Tape-Fed Packaging — Radial, can-style SMD package designed for automatic mounting machines fed with carrier tape to simplify automated assembly.
• Polarized Electrolytic — Polar capacitor construction for DC bulk storage and decoupling applications.
• RoHS Compliance — Meets RoHS directive requirements (2011/65/EU, EU2015/863).
• Soldering Heat Resistance — Meets specified characteristic requirements after exposure to soldering-heat test conditions described in the series datasheet.

Typical Applications

• Automotive Electronic Modules — Suited for automotive systems that require AEC-Q200 qualification and sustained operation at elevated temperatures up to +105°C.
• Power Supply Bulk Storage — Provides bulk capacitance for 25 V power rails where 2.9 mF and high ripple-current capability are required.
• DC-DC Converter Output Filtering — Low-impedance characteristic and specified ripple-current ratings support smoothing and filtering at converter outputs.

Unique Advantages

• AEC-Q200 Qualification: Enables use in automotive-grade designs that require component-level qualification for reliability.
• High-Temperature Reliability: 5000 hours endurance at 105°C supports long-term operation in thermally demanding environments.
• High Ripple Current Handling: Specified ripple currents of 955 mA (120 Hz) and 1.91 A (10 kHz) help maintain performance under AC stress.
• Automated Assembly Ready: Tape-fed, surface-mount radial can package simplifies placement with automatic mounting machines.
• Regulatory Compliance: RoHS conformity ensures regulatory alignment for worldwide manufacturing and assembly.
