UPW0J331MED

The UPW0J331MED is a radial‑lead aluminum electrolytic capacitor designed for miniature, low‑impedance power filtering. It delivers 330 µF at 6.3 V in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

Optimized for switching power supplies and space‑constrained electronic modules, the part combines low loss (tanδ = 0.22 at 20°C, 120 Hz), measurable ripple capability, and a wide operating temperature range for reliable performance in demanding environments.

Key Features

• Electrical Characteristics — 330 µF capacitance at 6.3 V with tolerance ±20% (‑20% to +20%); tangent of loss angle (tanδ) 0.22 measured at 20°C, 120 Hz.
• Low Impedance / Ripple Handling — Low-frequency ripple current 188.5 mA at 120 Hz and high-frequency ripple current 290 mA at 10 kHz for effective smoothing in switching supplies.
• Leakage and Polarization — Polarized aluminum electrolytic construction with leakage current specified at 62.37 µA.
• Thermal and Endurance Performance — Wide operating temperature range of −55°C to +105°C and rated for 2000 hours at 105°C.
• Package and Mounting — Radial lead (can) package, miniature footprint φ6.3 × 11 mm, lead spacing 2.5 mm (tolerance ±0.5 mm); available in bulk or bag packing.
• AEC Qualification — Rated AEC‑Q200 (as provided), suitable for applications that require that level of component qualification.

Typical Applications

• Switching Power Supplies — Output and smoothing capacitor for compact switching regulators where low impedance and ripple capability are required.
• Automotive Electronics — Applicable in automotive modules that require AEC‑Q200 rated passive components across −55°C to +105°C.
• Space‑Constrained Power Modules — Miniature φ6.3 × 11 mm can provides capacitance in tight PCB layouts while maintaining radial‑lead mounting.

Unique Advantages

• Compact, high‑density form factor: φ6.3 × 11 mm can and 2.5 mm lead spacing allow integration into small power supply boards.
• Measurable low-loss behavior: tanδ = 0.22 at 20°C/120 Hz supports lower impedance behavior for improved filtering performance.
• Effective ripple handling: Rated ripple currents of 188.5 mA (120 Hz) and 290 mA (10 kHz) support both low‑ and high‑frequency smoothing needs.
• Wide temperature and endurance: −55°C to +105°C operation with 2000 hours endurance at 105°C for sustained performance in elevated‑temperature environments.
• AEC‑Q200 rating: Meets the provided AEC qualification level for use in electronic designs requiring that standard.
• Low leakage current: Specified leakage of 62.37 µA supports reliable charge retention and low standby losses.
