UUQ1E4R7MCL1GB

The UUQ1E4R7MCL1GB is a chip-type aluminum electrolytic capacitor designed for wide-temperature audio and electronic applications. It delivers 4.7 μF capacitance at a 25 V rating in a compact radial can SMD package intended for automatic pick-and-place assembly from carrier tape.

Targeted for demanding environments, this part is AEC-Q200 qualified and RoHS compliant, offering a specified operating range of −40°C to +105°C and endurance performance appropriate for board-level power decoupling and audio circuits in automotive and industrial systems.

Key Features

• Electrical Performance — 4.7 μF nominal capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20°C); polarization is required.
• Low Leakage — Leakage current after 1 minute at 20°C is specified as not more than 0.03CV or 4 μA, whichever is greater.
• Impedance and Loss — Maximum tan δ for the 25 V rating is 0.16 (120 Hz, 20°C); low-temperature impedance ratios for 25 V are Z(−25°C)/Z(+20°C) = 2 and Z(−40°C)/Z(+20°C) = 3, supporting stable performance across the rated temperature range.
• Ripple Current — Specified ripple currents of 13 mA at 120 Hz and 19.5 mA at 10 kHz for typical filtering and decoupling applications.
• Temperature & Endurance — Rated for −40°C to +105°C. Endurance specified as 1000 hours at 105°C with rated voltage applied; capacitance change within ±20%, tan δ within 200% of initial, and leakage current within initial limits after test.
• Robust Solderability — Meets resistance-to-soldering-heat criteria: exposure to 250°C hot plate for 30 seconds results in capacitance change within ±10% and maintained electrical characteristics.
• Compact Package — Chip dimensions L: 5.4 × D: 4 mm with recommended PCB land size L: 4.3 × W: 4.3 mm; radial can SMD construction for dense board layouts.
• Assembly Compatibility — Applicable to automatic mounting machines when fed with carrier tape, facilitating high-volume PCB assembly.
• Quality & Compliance — AEC-Q200 qualified and compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronic Modules — AEC-Q200 qualification and −40°C to +105°C operation make this capacitor suitable for in-vehicle audio, infotainment, and body electronics where board-level filtering and decoupling are required.
• Audio Equipment — Part of Nichicon’s chip-type acoustic series designed for audio use, providing stable capacitance and low loss for signal coupling and power smoothing in compact audio boards.
• Industrial Control Electronics — Compact SMD radial can package and 1000-hour endurance at 105°C support power supply filtering and decoupling in industrial control and sensor interface modules.
• High-volume Surface-mount Assemblies — Carrier-tape compatibility and small footprint enable automated assembly for consumer and professional electronics requiring reliable electrolytic capacitance.

Unique Advantages

• Automotive-Grade Qualification: AEC-Q200 qualification provides documented suitability for automotive electronic designs that require component-level reliability.
• Wide Operating Temperature: −40°C to +105°C rating supports use across harsh thermal environments common in automotive and industrial applications.
• Validated Endurance: 1000 hours at 105°C with rated voltage applied ensures predictable ageing and performance for long-term deployments.
• Compact, Assembly-Friendly Package: Small L: 5.4 × D: 4 mm chip can with carrier-tape mountability simplifies BOM and accelerates automated PCB assembly.
• Measured Low Leakage: Leakage current limit of 0.03CV or 4 μA (whichever is greater) supports low-standby-current and precision circuitry requirements.
• Soldering Robustness: Resistance to soldering heat (250°C for 30 s) minimizes risk during reflow and board-level processing.
