The UCW1E331MNL1GS is an aluminum electrolytic chip capacitor in Nichicon's UCW series designed for surface-mount assembly. It delivers 330 µF capacitance at a 25 V rating in a compact radial can SMD package compatible with carrier-tape feed.

Targeted at automotive applications, this part offers low-impedance performance up to +105°C and a rated load life of 7000 hours at +105°C, combined with AEC-Q200 qualification and RoHS compliance for regulated environments.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at 25 V rated voltage, with ±20% tolerance.
• Long life at elevated temperature — Rated load life of 7000 hours at +105°C as specified for endurance.
• Low impedance performance — Specified impedance of 220 mΩ and designed for low impedance across the temperature range up to +105°C.
• Ripple current capability — Rated ripple current: 300 mA at 120 Hz and 600 mA at 10 kHz.
• Package & mounting — Chip type radial can in an SMD package; applicable to automatic mounting machines fed with carrier tape. Surface-mount design with surface-mount land size L: 8.3 × W: 8.3 mm.
• Environmental & quality standards — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).
• Operating conditions — Rated for operation from −25°C to +105°C; polarized device.
• Compact footprint — Physical size L: 1 × D: 0.8 cm providing a small SMD can for space-constrained designs.

Typical Applications

• Automotive electronics — Suited for automotive systems where AEC-Q200 qualification and operation to +105°C are required.
• Power-supply filtering — Use in modules or circuits that require a 330 µF, 25 V electrolytic capacitor with specified ripple handling and low impedance.
• Automated surface-mount assembly — Compatible with carrier-tape feeding for automatic placement in production lines.

Unique Advantages

• Extended high-temperature life: 7000 hours at +105°C provides predictable endurance in elevated-temperature environments.
• AEC-Q200 qualification: Explicit qualification for automotive-grade reliability where that standard is required.
