UUL1C331MNL1GS

The UUL1C331MNL1GS is a chip-type aluminum electrolytic capacitor designed for surface mounting on high-density PC boards. It delivers 330 µF at 16 V in a compact SMD radial can package and is optimized for applications that require long life and elevated temperature tolerance.

Built for demanding environments, this part is AEC-Q200 qualified and RoHS compliant, offering a rated operating temperature range of −40 °C to +105 °C with a rated load life of 5000 hours at +105 °C.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 16 V with a capacitance tolerance of ±20% (120 Hz, 20 °C).
• Long Life / High Temperature — Load life of 5000 hours at +105 °C; endurance specification allows capacitance change within ±30% after the rated life when restored to 20 °C.
• AEC-Q200 Qualified — Series qualification for automotive-grade reliability; suitable for designs requiring industry-recognized component qualification.
• Surface Mount Chip Package — Chip-type, surface-mount radial can designed for high-density PCB assembly with a package footprint sized at L: 1.03 × W: 1.03 cm (recommended land size).
• Operating Temperature Range — Rated for −40 °C to +105 °C to support elevated-temperature operation.
• Ripple Current Capability — Rated ripple current of 238 mA at 120 Hz and 357 mA at 10 kHz for effective smoothing and decoupling performance under AC stress.
• Low Leakage — Leakage current specification: after 2 minutes’ application of rated voltage at 20 °C, leakage is not more than 0.01 CV or 3 µA, whichever is greater.
• Soldering Heat Resistance — Meets soldering heat resistance test at 250 °C for 30 seconds with capacitance change within ±10% and leakage/tan δ within specified limits.

Typical Applications

• Automotive Electronics — Designed for automotive systems where AEC-Q200 qualification, long life at elevated temperature, and RoHS compliance are required.

Unique Advantages

• Long-term high-temperature stability — 5000-hour rated life at +105 °C supports reliability in prolonged elevated-temperature operation.
• Automotive-grade qualification — AEC-Q200 qualification provides traceable suitability for automotive electronic designs.
• Compact surface-mount form factor — Chip-type radial can enables high-density PCB layouts while providing electrolytic capacitance values not easily achieved with smaller MLCCs.
• Measurable ripple handling — Specified ripple current ratings at both low and high frequencies help designers size capacitors for power smoothing and decoupling tasks.
• Low leakage characteristic — Defined leakage current limit after voltage application supports predictable power budget and standby behavior.
• RoHS compliant — Conforms to RoHS directive requirements, supporting regulatory compliance for assemblies.
