The UCM2A391MNS1MS is a chip-type aluminum electrolytic capacitor in a surface-mount can package designed for applications that require high capacitance at elevated voltages. It offers a 390 µF capacitance at a 100 V rating with low-impedance characteristics and a temperature range from −55°C to 105°C.

Targeted for demanding environments, this part delivers high ripple-current capability, AEC-Q200 qualification, and long-term endurance for use in automotive and other reliability-focused systems.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable where substantial bulk capacitance is required at high rail voltages.
• Low Impedance Performance — Designed as a low-impedance chip type; tangent of loss angle (tan δ) is specified at 0.07 (20°C, 120 Hz) for the 100 V rating, supporting efficient AC performance.
• High Ripple-Current Capability — Rated ripple current of 1.02 A at 120 Hz (low frequency) and 2.04 A at 10 kHz (high frequency), enabling effective smoothing and decoupling under AC load conditions.
• Reliability & Endurance — AEC-Q200 rated and engineered for 5000 hours of endurance at 105°C, with leakage current of 390 µA, supporting long-term operation in harsh environments.
• Wide Temperature Range — Operates from −55°C to 105°C to accommodate wide ambient and thermal conditions.
• Surface-Mount, Carrier-Tape Packaging — Chip-type radial can for surface-mount assembly, supplied in embossed carrier taping for automated placement; vibration resistant construction for robust field performance.
• RoHS Compliant — Conforms to RoHS requirements, supporting use in modern regulated build environments.

Typical Applications

• Automotive Power Electronics — Bulk decoupling and filtering on 100 V rails in automotive systems that require AEC-Q200-qualified components and extended temperature operation.
• High-Voltage DC Power Supplies — Energy storage and smoothing where 390 µF at 100 V is needed together with high ripple-current handling.
• Industrial Power Modules — Input/output decoupling in industrial converters and power assemblies operating across −55°C to 105°C.

Unique Advantages

• High-Voltage Bulk Storage: 100 V rating with 390 µF capacitance provides significant energy storage for high-voltage rails.
• Improved AC Performance: Low tan δ and specified high-frequency ripple current (2.04 A at 10 kHz) help reduce losses and improve filtering effectiveness under dynamic loads.
• Automotive-Grade Reliability: AEC-Q200 rating and 5000-hour endurance at 105°C offer a dependable option for automotive and similarly demanding applications.
• Robust Packaging for SMT: Chip-type can in embossed carrier taping supports automated assembly and includes vibration-resistant design for secure long-term mounting.
• Wide Operating Range: −55°C to 105°C operation expands usability across harsh thermal environments.
