UCD2A151MNS1MS

The UCD2A151MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly on high-density PCBs. It delivers 150 µF capacitance at a 100 V rating with a compact φ16 × 16.5 mm can and embossed carrier tape packaging for automated placement.

Engineered for demanding power electronics, this capacitor combines low loss (tanδ 0.07 at 20°C/120 Hz), wide temperature operation (−55°C to 105°C), and proven endurance (5,000 hours at 105°C), making it suitable for applications that require stable filtering and ripple handling under elevated temperatures.

Key Features

• Capacitance & Tolerance 150 µF nominal with tolerance −20% to +20% for predictable energy storage and decoupling performance.
• Rated Voltage & Polarization 100 V rated, polarized electrolytic design for high-voltage power rails and DC-link applications.
• Low Impedance / Low Loss tanδ = 0.07 (20°C, 120 Hz) for reduced ESR-related losses and improved ripple handling.
• Ripple Current Capability Low-frequency ripple current 396.5 mA (120 Hz) and high-frequency ripple current 793 mA (10 kHz) for effective smoothing in switching supplies.
• Temperature & Endurance Operates from −55°C to +105°C with a rated lifetime of 5,000 hours at 105°C, supporting long-term performance in elevated-temperature environments.
• Package & Mounting Chip-type radial can in an SMD package (φ16 × 16.5 mm) with embossed carrier taping, compatible with automatic mounting machines for high-volume production.
• Reliability & Industry Qualification AEC-Q200 qualified and vibration resistant, suitable for demanding applications requiring validated component reliability.
• Leakage & Compliance Leakage current specified at 150 µA and RoHS compliant.

Typical Applications

• Automotive Power Electronics Bulk filtering and smoothing on high-voltage automotive power rails and control modules where AEC-Q200 qualification adds design confidence.
• DC–DC Converters and Power Supplies Input/output decoupling and energy storage for switching regulators and power-supply modules handling up to 100 V.
• Industrial Drives & Motor Control DC-link and ripple suppression for inverter and motor-drive circuits exposed to elevated temperatures and vibration.
• High-Density PCB Designs Surface-mount chip form factor and embossed carrier tape packaging enable automated placement on compact, densely populated boards.

Unique Advantages

• High-voltage capability: 100 V rating enables use on higher-voltage rails without series stacking.
• Long endurance at elevated temperature: 5,000 hours at 105°C provides predictable lifetime for thermal-stressed designs.
• Low-loss performance: tanδ = 0.07 reduces dissipation and improves stability in AC and ripple-heavy environments.
• Dual-frequency ripple handling: Specified ripple currents at both 120 Hz and 10 kHz support performance across low- and high-frequency converter designs.
• Automated assembly ready: Embossed carrier taping and SMD chip form support high-volume automated placement and efficient manufacturing.
• Automotive-grade reliability: AEC-Q200 qualification and vibration resistance align with stringent reliability requirements.
