UWT1H4R7MCL1GB

The UWT1H4R7MCL1GB is a chip-type aluminum electrolytic capacitor from Nichicon’s UWT series, engineered for surface-mount use on high-density printed circuit boards. It delivers a 4.7 µF capacitance at a 50 V rating in a compact SMD radial-can package.

Designed for automated assembly and demanding temperature environments, this part targets automotive and industrial electronics where AEC-Q200 qualification, wide operating temperature, and RoHS compliance are required. The capacitor is rated for 1000 hours at 105°C to support long-term operation in elevated-temperature conditions.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal with ±20% tolerance at 120 Hz, 20°C.
• Voltage Rating — Rated for 50 V operation.
• Temperature Range & Endurance — Operates from −55°C to +105°C; endurance specified as 1000 hours at 105°C.
• Package & Mounting — Chip-type radial, can-style SMD intended for surface mounting on high-density PC boards and compatible with carrier-tape automatic placement.
• Electrical Characteristics — Polarized construction; ripple current handling of 19 mA at 120 Hz and 28.5 mA at 10 kHz.
• Leakage Current Specification — After 2 minutes’ application of rated voltage at 20°C, leakage current is ≤ 0.01CV or 3 µA, whichever is greater (per datasheet).
• Reliability & Compliance — AEC-Q200 qualified and RoHS directive compliant (2011/65/EU, (EU)2015/863).
• Recommended PCB Land Pattern — Surface mount land size: 5.3 mm × 5.3 mm (as specified).

Typical Applications

• Automotive electronics — Suitable for electronic modules and subsystems that require AEC-Q200 qualification and wide temperature operation.
• High-density SMD assemblies — Chip-type SMD format and carrier-tape compatibility streamline automated placement on compact PCBs.
• Power filtering and decoupling — 4.7 µF, 50 V polarized capacitor appropriate for smoothing and decoupling duties on power rails in space-constrained designs.

Unique Advantages

• Wide temperature capability — Operation from −55°C to +105°C with 1000-hour endurance at 105°C, helping ensure stable performance in elevated-temperature environments.
• Automotive-grade qualification — AEC-Q200 qualification supports use in applications with automotive reliability requirements.
• Assembly-friendly package — Chip-type radial-can SMD design and carrier-tape compatibility reduce handling complexity for high-volume automated assembly.
• Predictable leakage behavior — Datasheet leakage-current limit (≤ 0.01CV or 3 µA after 2 minutes at 20°C) aids in predictable bias performance in designs.
• Environmental compliance — RoHS directive conformity for regulatory and environmental requirements.
• Compact SMD format — Radial can SMD construction supports high-density PCB layouts without sacrificing rated capacitance or voltage.
