UUJ1E102MNJ1MS

The UUJ1E102MNJ1MS is a chip-type aluminum electrolytic capacitor designed for surface mounting on high-density PC boards. It delivers 1 mF capacitance at a 25 V rating in a compact can-style SMD package optimized for automated carrier-tape assembly.

Engineered for demanding environments, this part is RoHS-compliant and AEC-Q200 qualified, and it provides long-term performance across a wide temperature range with a rated lifetime of 5000 hours at 105 °C.

Key Features

• Capacitance & Voltage: 1 mF rated capacitance at 25 V for bulk decoupling and energy storage in compact assemblies.
• Package & Mounting: Chip-type radial can SMD (φ18 × 16.5 mm / 18 mm × 16.5 mm) sized for surface-mount, with carrier-tape compatibility for automatic pick-and-place.
• Temperature Range: Operates from −55 °C to 105 °C (rated for 10–100 V category in the series), supporting broad environmental conditions.
• Endurance: Rated for 5000 hours at 105 °C; after this test the capacitor meets specified limits for capacitance, tan δ, and leakage current as defined in the datasheet.
• Ripple Current: 700 mA at 120 Hz and 805 mA at 10 kHz, supporting common low- and high-frequency ripple conditions.
• Tolerance & Polarization: Capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C); polarized construction.
• Leakage Current (per datasheet): After 1 minute’s application of rated voltage at 20 °C, leakage current is not more than 0.03CV (μA) for the 10–100 V range.
• Electrical Loss & Low-Temp Stability: Characterized tan δ and impedance ratios are provided in the series datasheet (for 25 V, tan δ max 0.16; Z(−25 °C)/Z(+20 °C) and Z(−40 °C)/Z(+20 °C) follow series specifications).
• Compliance & Qualification: RoHS-compliant and AEC-Q200 qualified for designs requiring recognized reliability standards.

Typical Applications

• Automotive modules: Suitable for automotive electronic assemblies that require surface-mount, high-capacitance components with AEC-Q200 qualification.
• High-density PCB power rails: Provides bulk capacitance in compact SMD form for smoothing and decoupling on space-constrained boards.
• Power supply filtering: Handles low- and high-frequency ripple currents for local energy storage and filtering functions in power subsystems.

Unique Advantages

• High capacitance in compact SMD can: 1 mF in a φ18 × 16.5 mm chip-type package delivers significant energy density for space-constrained designs.
• Automotive-grade reliability: AEC-Q200 qualification and 5000-hour endurance at 105 °C support designs requiring validated long-term performance.
• Wide operating temperature: −55 °C to 105 °C rating covers a broad range of environmental conditions common in embedded and vehicular applications.
• Mounting and assembly ready: Designed for surface mounting and compatible with carrier-tape feeding for automated assembly lines.
• Standards-compliant materials: RoHS compliance ensures compatibility with environmental regulatory requirements.
• Characterized ripple capability: Documented ripple current at 120 Hz and 10 kHz helps match the part to expected power-system stressors.
