UPW0J331MED6

The UPW0J331MED6 is an aluminum electrolytic capacitor in a miniature radial-lead can, engineered for power-filtering roles in switching power supplies and compact power assemblies. It combines a 330 µF capacitance with a 6.3 V rated voltage and a low-impedance construction to support stable regulator performance and decoupling in space-constrained designs.

Built for demanding environments, this part supports a wide operating temperature range and carries an AEC-Q200 rating, providing a reliable option for automotive and other high-reliability applications that require robust electrolytic filtering.

Key Features

• Capacitance & Voltage: 330 µF at 6.3 V nominal — suitable for bulk decoupling and smoothing in low-voltage power rails.
• Low Impedance Design: Engineered for reduced impedance to improve transient response and reduce ripple-induced voltage variation in switching supplies.
• Compact, Radial-Lead Package: Radial, can-style package with 2.5 mm lead spacing and a small diameter (D: 0.63 cm, L: 1.5 cm) to save PCB area in compact assemblies.
• High Ripple Handling: Rated ripple current of 279.5 mA at 120 Hz and 430 mA at 10 kHz, supporting both low- and high-frequency ripple conditions common in switching regulators.
• Wide Temperature Range: Specified for –55 °C to +105 °C operation for use across a broad set of thermal environments.
• Polarized Electrolytic: Polar capacitor with ±20% capacitance tolerance at 120 Hz, 20 °C.
• AEC‑Q200 Rating: Meets AEC‑Q200 qualification, addressing reliability demands for automotive and similarly stringent applications.
• Designed for Reliability: Rated lifetime of 2000 hours at 105 °C for long-term performance under elevated temperature stress.

Typical Applications

• Switching Power Supplies: Bulk and output-stage filtering where low impedance and high ripple capability stabilize regulator outputs and improve transient performance.
• Automotive Electronics: AEC‑Q200-rated filtering and decoupling in automotive control modules and in-vehicle power systems that require temperature and reliability endurance.
• Compact Power Modules: Space-constrained DC/DC converters and power assemblies that benefit from a small radial-lead footprint and strong ripple performance.

Unique Advantages

• Space-efficient form factor: Small diameter and short length allow high-density placement in compact power designs.
• Improved regulator stability: Low impedance and specified ripple currents at 120 Hz and 10 kHz help maintain cleaner rails under switching conditions.
• Automotive-capable qualification: AEC‑Q200 rating supports use in designs with automotive-grade reliability requirements.
• Wide operating temperature: –55 °C to +105 °C specification enables deployment across diverse thermal environments.
• Durability at elevated temperature: 2000 hours rated life at 105 °C for sustained performance in high-temperature applications.
• Through-hole robustness: Radial lead mounting provides mechanical resilience for vibration-prone assemblies and ease of prototyping or repair.
