UUR1C331MNL1GS

The UUR1C331MNL1GS is a chip-type, high-capacitance aluminum electrolytic capacitor from Nichicon's UUR series, engineered for surface mounting on high-density printed circuit boards. It provides 330 µF at 16 V in a compact SMD can (radial, can - SMD) that is compatible with carrier-tape feeding for automated assembly.

Designed for demanding board-level power smoothing and energy storage, this part is AEC-Q200 rated and RoHS compliant, making it suited to applications requiring automotive-grade reliability and regulatory compliance within its specified operating conditions.

Key Features

• Chip-Type, High CV  High capacitance (330 µF) in a chip-style aluminum electrolytic package optimized for surface-mount, high-density PCB layouts.
• Rated Voltage & Tolerance  Rated for 16 V with capacitance tolerance of ±20% (–20% to +20%), suitable for common low-voltage power-rail filtering.
• Package & Mounting  Radial can in an SMD footprint designed for carrier-tape automatic mounting, enabling pick-and-place assembly on automated lines.
• Operating Range & Endurance  Specified for operation from –40 °C to +85 °C with an endurance rating of 2000 hours at 85 °C when subjected to rated voltage.
• Ripple Current Capability  Rated ripple performance of 270 mA at 120 Hz and 351 mA at 10 kHz for effective AC ripple handling in power applications.
• Automotive and Regulatory  AEC-Q200 compliant and RoHS compliant (2011/65/EU, (EU)2015/863), aligning with automotive reliability and environmental requirements.
• Polarized Electrolytic  Polarized design for DC filtering and energy storage on power rails.
• Compact Footprint  Physical dimensions approximately L: 1.0 × D: 0.8 cm, delivering high CV in a small board area.

Typical Applications

• Automotive Power Modules  Bulk decoupling and smoothing on 12 V/24 V subsystems and control modules where AEC-Q200 compliance is required.
• Power Supply Filtering  Input/output smoothing and transient energy buffering on compact DC–DC converters and regulators in space-constrained designs.
• Embedded Control Electronics  Board-level energy storage and ripple suppression for microcontroller and sensor power rails in dense assemblies.

Unique Advantages

• High Capacitance in a Small SMD Can  Delivers 330 µF in a compact chip-type package to save board area while maintaining required energy storage.
• Automotive-Grade Reliability  AEC-Q200 compliance supports use in applications that demand proven component-level reliability within the specified operating envelope.
• Assembly-Friendly  Carrier-tape compatibility enables efficient automated pick-and-place mounting, streamlining manufacturing for high-volume production.
• Defined Thermal Endurance  2000 hours at 85 °C endurance rating provides a measurable reliability metric for thermal life planning and validation.
• Measurable Ripple Performance  Specified ripple current at both 120 Hz and 10 kHz helps designers predict heating and lifetime under real-world load conditions.
• Regulatory Compliance  RoHS compliance supports environmentally regulated designs and supply-chain requirements.
