UCM2A511MNS1MS

The UCM2A511MNS1MS is a surface-mount aluminum electrolytic chip capacitor designed for high-voltage, high-reliability applications. It combines a 510 µF capacitance at a 100 V rated voltage with a chip-type, low-impedance construction and is supplied in embossed carrier tape for automated PCB assembly.

Targeted for automotive and other demanding electronic systems, this AEC-Q200 qualified, RoHS-compliant component offers high ripple handling, extended endurance at elevated temperatures, and vibration resistance for robust in-field performance.

Key Features

• Capacitance & Voltage: 510 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for high-voltage rails.
• Chip, Low-Impedance Construction: Chip-type design marketed as low impedance to support high ripple currents and reduce ESR-related losses.
• High Ripple Capability: Rated ripple current of 1.07 A at 120 Hz (low frequency) and 2.14 A at 10 kHz (high frequency), enabling effective smoothing and decoupling in power circuits.
• Loss and Leakage: tanδ (DF) 0.07 measured at 20°C, 120 Hz, 100 V; leakage current specified at 510 µA (after standard voltage application conditions).
• High-Temperature Endurance: Rated lifetime of 5000 hours at 105°C, with endurance specifications defined after restoration to 20°C following test conditions.
• Robust Packaging & Mounting: Surface mount, radial can SMD package (φ18 × 21.5 mm) with embossed carrier taping and a surface-mount land size of 18.3 × 18.3 mm for automated placement.
• Environmental & Qualification: RoHS compliant and AEC-Q200 qualified; vibration-resistant construction is specified for applicable sizes.
• Operating Range: Specified for operation from −55°C to +105°C, suitable for wide temperature environments.

Typical Applications

• Automotive power electronics: Bulk filtering and energy storage on high-voltage rails where AEC-Q200 qualification and a 100 V rating are required.
• DC–DC converters and inverters: Support for smoothing and ripple suppression leveraging the capacitor's high ripple current capability and low DF.
• Industrial power supplies: High-temperature endurance (5000 h at 105°C) and robust mounting make it suitable for power modules in harsh operating environments.

Unique Advantages

• High-voltage capability: 100 V rated voltage enables use on elevated DC rails without additional series components.
• High ripple performance: Measured ripple ratings at both 120 Hz and 10 kHz allow designers to address both low- and high-frequency ripple in power systems.
• Long life at elevated temperature: 5000-hour endurance at 105°C provides predictable aging behavior for long-term reliability planning.
• Automated assembly ready: Embossed carrier taping and SMD can packaging streamline placement and reduce assembly cost and complexity.
• Qualification and compliance: AEC-Q200 qualification and RoHS compliance support use in regulated and automotive-focused designs.
• Vibration resistant: Construction specified as vibration resistant for applicable sizes to enhance survivability in mobile and harsh environments.
