UCX1C331MCL1GS

The UCX1C331MCL1GS from Nichicon is a chip-type aluminum electrolytic capacitor engineered for reliable operation in high-temperature and automotive environments. Designed for surface-mount assembly with carrier-tape compatibility, it delivers 330 µF capacitance at a 16 V rating with a compact SMD can footprint.

Key value comes from a wide operating temperature window (−40 °C to +135 °C), an ESR specification validated after −40 °C testing, AEC-Q200 qualification, and endurance specified for extended high-temperature service.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 16 V, with tolerance ±20% measured at 120 Hz, 20 °C.
• High temperature endurance — Rated for operation up to +135 °C with a defined endurance of 2000 hours at 135 °C under rated voltage.
• Low-temperature ESR specification — ESR characterized after −40 °C testing; specified equivalent series resistance is 150 mΩ at 100 kHz.
• AEC-Q200 Qualified — Built to the AEC-Q200 qualification standard for enhanced reliability in automotive-grade applications.
• Surface-mount chip can — Chip-type, radial can SMD package suitable for automatic mounting machines fed with carrier tape; compact dimensions (L: 1 cm × D: 1 cm) with a seated height up to 1 cm.
• Ripple current capability — Specified ripple current of 250 mA at 120 Hz (low frequency) and 500 mA at 10 kHz (high frequency).
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Electrical stability — Endurance criteria: after 2000 hours at 135 °C with rated voltage applied, capacitance change within ±30%, tan δ within 300% of initial specified value, and leakage current not exceeding initial spec.

Typical Applications

• Automotive electronics — Suitable for electronic control units and modules that require AEC-Q200 qualified capacitors with high-temperature endurance.
• High-temperature systems — Components that must operate reliably up to +135 °C while maintaining capacitance and ESR performance.
• Automated surface-mount production — Chip-type can packaged for carrier-tape feeding and automatic placement on SMD assemblies.
• Power filtering where low-temperature ESR matters — Applications that require verified ESR behavior after −40 °C conditions and controlled ripple handling at both low and high frequencies.

Unique Advantages

• Validated high-temperature life: 2000 hours at 135 °C under rated voltage provides a clear, measured endurance metric for thermal-stressed designs.
• Low-temperature ESR assurance: ESR specified after −40 °C testing (150 mΩ at 100 kHz) helps maintain performance across the full operating range.
• AEC-Q200 qualification: Confirms suitability for automotive-grade reliability requirements where specified.
• Compact, assembly-friendly package: Chip-type SMD can with carrier-tape compatibility simplifies integration into automated production lines.
• Measured ripple handling: Rated ripple currents at 120 Hz and 10 kHz allow designers to size capacitors against real-world AC loading conditions.
• Regulatory compliance: RoHS conformity supports restricted-substance requirements in modern supply chains.
