UWT1V331MNL1GS

The UWT1V331MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UWT series, designed for surface mounting on high-density PC boards. It delivers 330 µF at 35 V in a compact SMD can package optimized for automated carrier-tape placement.

Engineered for demanding environments, this capacitor supports a wide operating temperature range of −55°C to +105°C, is RoHS-compliant, and carries AEC-Q200 qualification for applications that require automotive-grade reliability.

Key Features

• Electrical Performance — 330 µF rated capacitance at 35 V with ±20% tolerance, providing bulk capacitance for power rail smoothing and decoupling.
• Ripple Current Capability — Specified ripple current of 300 mA at 120 Hz and 450 mA at 10 kHz to support real-world AC loading and switching environments.
• Wide Temperature Range — Operating range from −55°C to +105°C for use across extended temperature environments.
• High-Temperature Endurance — Rated for 1000 hours at 105°C with defined endurance limits for capacitance, tan δ and leakage current.
• Reliability & Qualification — AEC-Q200 qualified and RoHS-compliant (2011/65/EU, (EU)2015/863), addressing supply-chain and industry quality requirements.
• Surface-Mount Chip Can Package — Radial can SMD package sized approximately 1.0 × 1.0 cm with a recommended land size of 1.03 × 1.03 cm, compatible with automated carrier-tape mounting.
• Leakage & Loss Characteristics — Defined leakage current limit (0.01CV or 3 µA after 2 minutes at 20°C) and tan δ specifications by rated voltage for predictable behavior in designs.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and −55°C to +105°C operation make this capacitor suitable for automotive electronic modules that require robust temperature and qualification coverage.
• High‑Density PCB Power Modules — Chip SMD can package and carrier-tape compatibility enable automated placement in compact power supply and converter assemblies on dense PCBs.
• Power Rail Filtering and Bulk Decoupling — 330 µF capacitance combined with specified ripple current ratings supports smoothing and decoupling in power management circuits.

Unique Advantages

• Automotive‑grade qualification: AEC-Q200 rating provides documented qualification for designs targeting automotive and similarly demanding applications.
• Wide operating range: −55°C to +105°C supports reliability across extreme ambient and under-hood temperature conditions.
• Compact, mountable form factor: 1.0 × 1.0 cm chip can and carrier-tape compatible packaging simplify automated assembly for high-density PCB layouts.
• Long high‑temperature life: 1000 hours at 105°C gives designers a clear endurance baseline for thermal-stress planning.
• Measured ripple handling: Specified ripple currents at both 120 Hz and 10 kHz allow designers to size capacitors based on actual ripple loading.
• Regulatory compliance: RoHS conformity (2011/65/EU, (EU)2015/863) supports restricted-substance requirements for regulated markets.
