UCM1K751MNS1MS

The UCM1K751MNS1MS is a chip-type aluminum electrolytic capacitor engineered for surface-mount assembly where low impedance and high-voltage capability are required. With a rated voltage of 80 V and 750 µF capacitance, it targets robust power applications in systems that require long endurance and reliable ripple performance.

This part is AEC-Q200 qualified and RoHS compliant, and is supplied in embossed carrier taping for automated mounting. It combines high-frequency ripple handling and extended life at elevated temperature to support demanding electronic designs.

Key Features

• Capacitance & Voltage — 750 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Loss / Low Impedance — Tangent of loss angle (tan δ) specified at 0.08 (measured at 20°C, 120 Hz), providing predictable loss characteristics for power filtering.
• High Ripple Current Capability — Low-frequency ripple current 1.07 A (120 Hz) and high-frequency ripple current 2.14 A (10 kHz) to support both bulk filtering and higher-frequency decoupling tasks.
• Leakage and Endurance — Leakage current specified at 600 µA and endurance rated for 5000 hours at 105°C with performance limits defined after restoration to 20°C.
• Automotive-Ready Reliability — AEC-Q200 qualification and vibration-resistant construction suitable for vehicle electronics and other demanding environments.
• Surface-Mount, Tape-Packaged — Chip-type, SMD radial can for automated placement; supplied on embossed carrier tape for high-throughput assembly.
• Wide Operating Temperature — Rated for operation from −55°C to 105°C to match elevated-temperature system environments.
• Standards & Compliance — RoHS compliant per applicable directives.

Typical Applications

• Automotive Power Modules — AEC-Q200 qualification, high voltage rating and long endurance make this capacitor suitable for power-supply filtering and energy buffering in automotive electronic control units.
• DC–DC Converters — High ripple-current capability at both low and high frequencies supports bulk and decoupling roles in converter outputs and intermediate bus filtering.
• Power Electronics — Robust temperature and endurance specifications support use in inverters, motor controllers, and other power-management assemblies that demand sustained thermal performance.

Unique Advantages

• High-Voltage, High-Capacitance in SMD Format: 80 V rating with 750 µF capacitance provides substantial energy storage while fitting automated surface-mount assembly flows.
• Balanced Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz give designers quantified margins for both low-frequency smoothing and higher-frequency noise suppression.
• Extended High-Temperature Life: 5000 hours endurance at 105°C helps ensure longer service life in thermally stressed environments.
• Automotive-Grade Qualification: AEC-Q200 qualification and vibration-resistant design reduce qualification burden for vehicle electronics designs.
• Manufacturing-Friendly Packaging: Embossed carrier taping enables reliable feed into automated pick-and-place equipment, simplifying production ramp.
