The UCM1H751MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. It delivers 750 µF capacitance at a 50 V rating in a compact φ12.5 × 21 mm can suitable for automated carrier-tape placement.

Engineered for demanding temperature and ripple environments, this AEC-Q200 qualified component supports operation from -55°C to 105°C, a 5000-hour endurance at 105°C, and high-frequency ripple handling—making it suitable for robust electronic power applications in automotive and industrial systems.

Key Features

• Capacitance & Voltage — 750 µF nominal capacitance with a rated voltage of 50 V and ±20% tolerance at 120 Hz, 20°C.
• Low Impedance — Rated impedance of 80 mΩ and tan δ of 0.10 (measured at 120 Hz, 20°C), supporting stable performance under AC stress.
• High Ripple Current Capability — Low-frequency ripple current of 985 mA (120 Hz) and high-frequency ripple current of 1.97 A (100 kHz) for effective smoothing and decoupling under dynamic loads.
• Wide Temperature & Endurance — Operating range from -55°C to 105°C with a rated lifetime of 5000 hours at 105°C.
• Surface-Mount, Carrier-Tape Ready — Chip-type SMD package (φ12.5 × 21L) supplied in embossed carrier taping for automated placement.
• Automotive-Grade Reliability — AEC-Q200 qualification for use in automotive electronic assemblies.
• Leakage and Stability — Leakage current specified at 375 µA and stable characteristics after endurance and soldering-heat tests per datasheet criteria.

Typical Applications

• Automotive electronics — Energy storage and smoothing in vehicle power systems where temperature endurance and AEC-Q200 qualification are required.
• Power management modules — Filtering and decoupling in power supplies and converters that demand low impedance and high ripple current capability.
• Industrial control — Bulk capacitance in control and drive electronics operating across wide temperature ranges and extended lifetimes.

Unique Advantages

• High ripple handling: 1.97 A at 100 kHz and 985 mA at 120 Hz provide effective AC stress tolerance for switching and pulsed power designs.
• Low ESR/Impedance: 80 mΩ impedance and a tan δ of 0.10 improve voltage stability and reduce heat generation under load.
• Robust thermal performance: -55°C to 105°C operating range and 5000-hour endurance at 105°C support long-term reliability in harsh environments.
• Automotive qualification: AEC-Q200 rating supports use in automotive-grade assemblies requiring recognized component-level reliability.
• Surface-mount manufacturability: Embossed carrier taping and chip-type can package simplify automated placement and reduce assembly overhead.
• Verified leakage and stability: Specified leakage current and datasheet endurance criteria ensure predictable behavior after soldering and long-term operation.
