UWT1E331MNL1GS

The UWT1E331MNL1GS is an aluminum electrolytic chip capacitor in Nichicon's UWT series, designed for surface-mount assembly and use in demanding environments. It provides 330 µF capacitance at a 25 V rating in a compact radial can SMD package.

Engineered for wide temperature operation from −55 °C to +105 °C and AEC‑Q200 qualification, this part targets automotive and other high-reliability applications that require stable capacitance, defined ripple performance, and verified endurance at elevated temperatures.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, delivering substantial charge storage in a single SMD component.
• Wide Temperature Range — Specified for operation from −55 °C to +105 °C, supporting designs that must tolerate extreme ambient conditions.
• AEC‑Q200 Qualified — AEC‑Q200 rating for use in automotive-grade designs where qualification is required.
• Endurance & Lifetime — Rated for 1000 hours at 105 °C with defined limits on capacitance change, tan δ and leakage current after the endurance test.
• Surface Mount Radial Can — Chip-type, carrier-tape compatible SMD package with land size 8.3 × 8.3 mm and compact dimensions (L: 1.0 cm × D: 0.8 cm) for high-density PCBs.
• Electrical Performance — Polarized design with specified low-frequency ripple current of 190 mA (120 Hz) and high-frequency ripple current of 285 mA (10 kHz); leakage current specification of ≤0.01CV or 3 µA (whichever is greater) after 2 minutes at 20 °C.
• Regulatory Compliance — RoHS‑compliant material set.

Typical Applications

• Automotive electronics — Designed for automotive systems that require components qualified to AEC‑Q200 and operation across −55 °C to +105 °C.
• Power-supply decoupling and smoothing — 330 µF at 25 V with defined ripple current ratings supports bulk energy storage and smoothing in power rails where high capacitance in a compact SMD package is needed.
• High-density PCB assemblies — Chip-type radial can SMD format and carrier-tape compatibility enable automated placement on space-constrained boards.

Unique Advantages

• Wide operational temperature span: −55 °C to +105 °C rating ensures consistent electrical behavior across extreme environments.
• AEC‑Q200 qualification: Supports use in automotive-grade designs that require recognized component qualification.
• High capacitance in a compact SMD form: 330 µF in a 1.0 × 0.8 cm package reduces board area compared to larger through-hole alternatives.
• Defined ripple and leakage specifications: Ripple current ratings at 120 Hz and 10 kHz plus a clear leakage current limit simplify thermal and reliability margining.
• Proven endurance at elevated temperature: 1000 hours at 105 °C with specified limits on capacitance change and electrical characteristics for predictable long-term behavior.
• RoHS compliance: Meets regulatory material requirements for modern electronic assemblies.
