UCW1H101MNL1GS

The UCW1H101MNL1GS is a Nichicon UCW-series chip aluminum electrolytic capacitor designed for surface-mount applications. It combines a 100 µF / 50 V capacitance/voltage rating with a low-impedance construction and a long rated load life for use in demanding temperature environments.

Targeted at automotive and other high-reliability markets, this AEC-Q200 qualified, RoHS-compliant device offers 7000 hours of rated life at +105°C and is compatible with automated placement when supplied on carrier tape.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance at a 50 V rated voltage, specified with ±20% tolerance at 120 Hz, 20°C.
• Low Impedance — Low-impedance construction with a measured impedance of 530 mΩ, supporting stable performance across its temperature range.
• Extended Temperature Range — Rated for operation from −25°C to +105°C with maintained low impedance up to +105°C.
• Long Life Endurance — Load life specified as 7000 hours at +105°C; endurance characteristics restore to specified values after test conditions (capacitance within ±30% after endurance).
• Ripple Current Capability — Rated ripple currents of 175 mA at 120 Hz and 350 mA at 10 kHz for handling AC loading in power circuits.
• Surface-Mount Radial Can Package — Chip-type radial can in an SMD-compatible form factor (L: 1.0 cm × D: 0.8 cm) with recommended land size L: 8.3 mm × W: 8.3 mm for PCB footprint.
• AEC-Q200 Qualified & RoHS Compliant — Meets AEC-Q200 qualification and conforms to RoHS directive requirements.
• Automated Assembly Ready — Applicable to automatic mounting machines when supplied on carrier tape.

Typical Applications

• Automotive control modules — Bulk energy storage and smoothing on 50 V power rails where 7000 hours at +105°C lifecycle and AEC-Q200 qualification are required.
• Power-supply decoupling — Low impedance and specified ripple current make this capacitor suitable for decoupling and filtering in DC/DC converters and power-supply rails.
• Embedded electronics in harsh environments — Use in electronics that must operate across −25°C to +105°C with sustained performance over extended operational life.

Unique Advantages

• Long, specified high-temperature life: 7000 hours at +105°C provides predictable ageing behavior for designs requiring extended durability.
• Measurable low impedance: 530 mΩ impedance supports stable voltage smoothing and transient response in power circuits.
• Board-level efficiency: Surface-mount radial can and carrier-tape compatibility enable automated placement to reduce assembly time and variability.
• Automotive-grade reliability: AEC-Q200 qualification aligns the device with automotive development requirements where this standard is mandated.
• Clear end-of-life characterization: Endurance specifications (capacitance change within ±30% after rated life, tan δ and leakage current limits) help designers predict maintenance and replacement intervals.
