UBC1E331MNS1MS

The UBC1E331MNS1MS is a Nichicon UBC-series aluminum electrolytic, chip-style capacitor designed for surface-mount assemblies that require high-temperature endurance and vibration resistance. With a rated capacitance of 330 µF at 25 V, polarized construction, and a compact can-style SMD package, it targets electronics where sustained performance at elevated temperatures is critical.

Engineered for demanding environments, this capacitor is specified for continuous operation from -55°C to 150°C and delivers a rated load life of 1000 hours at 150°C, making it suitable for automotive electronics and other high-temperature, vibration-prone applications.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance for stable bulk energy storage in compact power circuits.
• High-Temperature Endurance — Rated operating range to 150°C and specified for 1000 hours at 150°C, enabling reliable operation in elevated-temperature systems.
• Vibration-Resistant Chip Design — Chip-type construction optimized for vibration resistance to maintain electrical and mechanical integrity in harsh environments.
• Ripple Current Performance — Handles 435.5 mA at 120 Hz and 650 mA at 100 kHz, providing effective ripple filtering for power-conditioning and decoupling tasks.
• Surface-Mount Can Package — Radial, can-style SMD package (L: 1.35 × D: 1.25 cm) with recommended land pattern (1.28 × 1.28 cm) for PCB integration in compact assemblies.
• AEC-Q200 Qualified & RoHS Compliant — Built to automotive-grade reliability standards (AEC-Q200) and compliant with RoHS directives for regulatory conformity.

Typical Applications

• Automotive Electronics — Suited for control modules and other vehicle electronics that require thermal endurance and vibration resistance.
• High-Temperature Power Conditioning — Bulk filtering and decoupling in power subsystems operating at elevated temperatures.
• Vibration-Prone Industrial Systems — Power and filtering applications in equipment subject to mechanical vibration where stable capacitance is required.
