UUL1H3R3MCL1GS

The UUL1H3R3MCL1GS from Nichicon is an aluminum electrolytic chip capacitor designed for surface mounting on high-density PC boards. It delivers a compact, polarized SMD can construction with a rated capacitance of 3.3 µF at 50 V and is specified for operation from -40 °C to 105 °C.

With a 5000-hour load life at 105 °C and AEC-Q200 qualification, this capacitor is targeted at automotive electronics and other environments that require long-life performance, regulatory compliance, and a small footprint.

Key Features

• Electrical Performance — 3.3 µF nominal capacitance at a 50 V rating with ±20% tolerance, suitable for decoupling and filtering uses where a polarized aluminum electrolytic is required.
• Long-Life Endurance — Rated for 5000 hours at +105 °C; after this life test the capacitor meets endurance criteria including capacitance change within ±30% and leakage current within initial specified limits.
• Temperature Range — Specified operating range from -40 °C to +105 °C, enabling use across wide temperature conditions.
• Reliability & Qualification — AEC-Q200 qualified and RoHS compliant (2011/65/EU.(EU)2015/863), meeting automotive-grade screening and environmental requirements.
• Compact SMD Package — Radial can, SMD chip format with overall dimensions L: 5.8 × D: 4 mm and recommended land size L: 4.3 × W: 4.3 mm for high-density PCB layouts.
• Leakage & Loss Characteristics — Leakage current specified as not more than 0.01 CV or 3 µA (whichever is greater) after 2 minutes at 20 °C; tan δ and impedance characteristics are provided per rated voltage in the datasheet.
• Ripple Current Ratings — Low-frequency ripple current of 14 mA at 120 Hz and high-frequency ripple current of 21 mA at 10 kHz, supporting common power-conditioning requirements.

Typical Applications

• Automotive electronics — AEC-Q200 qualification and long-life rating make this capacitor suitable for use in automotive electronic modules and systems.
• High-density PCB assemblies — Chip-type SMD can intended for surface mounting on high-density printed circuit boards where board space and reliable solder mounting are important.
• Temperature-challenging environments — Designed for operation across -40 °C to +105 °C with a 5000-hour life at 105 °C for applications requiring extended high-temperature endurance.

Unique Advantages

• Long operating life: 5000 hours at +105 °C provides proven endurance for designs that must tolerate prolonged high-temperature stress.
• Automotive-grade qualification: AEC-Q200 rating supports integration into automotive systems that require industry-recognized component screening.
• Compact SMD can: Small 5.8 × 4 mm chip package and specified land pattern enable space-efficient PCB layouts on high-density boards.
• Regulatory compliance: RoHS compliant (2011/65/EU, (EU)2015/863), simplifying regulatory management for assemblies.
• Measured leakage and loss specs: Clear leakage current limits and tan δ/impedance data in the datasheet help predict performance in filtering and decoupling roles.
• Ripple capability: Specified ripple current at both low and high frequencies (14 mA at 120 Hz, 21 mA at 10 kHz) supports common power-conditioning needs.
