UUT1H2R2MCL1GS

The UUT1H2R2MCL1GS from Nichicon is an aluminum electrolytic chip-type capacitor in the UUT series, engineered for surface-mount use on high-density PC boards. It delivers a 2.2 µF capacitance at a 50 V rating in a compact 5.8 × 4.0 mm package, combining small footprint and polarized electrolytic performance.

Designed for applications requiring extended high-temperature endurance, this part offers a 2000 hour load life at +105°C, AEC-Q200 reliability designation, and RoHS compliance, making it suitable for automotive and other demanding environments.

Key Features

• Form factor – Chip SMD (6 mm length): Compact radial can SMD package sized L: 5.8 × D: 4.0 mm with recommended land pattern L: 4.3 × W: 4.3 mm for automatic carrier-tape mounting and high-density PCB assembly.
• Electrical rating: 2.2 µF capacitance at 50 V rated voltage with polarization; capacitance tolerance −20% to +20%.
• High-temperature endurance: Rated for 2000 hours at +105°C under rated voltage, with defined limits for capacitance change, tan δ and leakage after endurance testing.
• Operating temperature range: −55°C to +105°C for broad ambient compatibility in thermal stress environments.
• Ripple current capability: Specified ripple current of 11 mA at 120 Hz and 16.5 mA at 10 kHz for decoupling and filtering applications across low and high frequency ranges.
• Low leakage current: Leakage current after 2 minutes at 20°C is specified as not more than 0.01 CV or 3 µA (whichever is greater), supporting low-standby and precision circuits.
• Quality and compliance: AEC-Q200 rated and RoHS compliant (2011/65/EU, (EU)2015/863), meeting industry environmental and reliability expectations for regulated markets.
• Automated assembly ready: Designed for surface mounting with carrier-tape feed compatibility for automatic mounting machines.

Typical Applications

• Automotive control modules: Bulk decoupling and smoothing on 50 V rails where AEC-Q200-level reliability and high-temperature endurance are required.
• Sensor and ECU electronics: Local power filtering and noise suppression in compact, high-density printed circuit assemblies operating across −55°C to +105°C.
• Industrial power electronics: Decoupling and transient absorption for compact DC-DC converters and control boards exposed to elevated ambient temperatures.

Unique Advantages

• Compact SMD footprint: 5.8 × 4.0 mm package supports high-density board layouts while keeping capacitance and voltage rating sufficient for many power and decoupling tasks.
• Extended high-temperature life: 2000 hours at +105°C provides predictable aging behavior for designs that must tolerate sustained elevated temperatures.
• Automotive-capable qualification: AEC-Q200 designation delivers confidence for vehicle electronics and similarly demanding applications.
• Low leakage characteristic: Tight leakage specification (0.01 CV or 3 µA min) helps preserve efficiency and accuracy in low-current circuits.
• Assembly-friendly design: Carrier-tape compatible chip form factor streamlines automated placement and reduces handling variability.
• Regulatory compliance: RoHS conformity supports use in regulated markets and meets environmental restrictions.
