UPM0J331MED

The UPM0J331MED from Nichicon is a radial-leaded aluminum electrolytic capacitor in the UPM series, offering 330 µF capacitance at a 6.3 V rating. Designed for polarized DC applications, this component combines a compact 6.3 mm diameter × 15 mm length can with AEC-Q200 qualification and RoHS compliance for use in demanding environments.

Its key value proposition is delivering high capacitance density and low loss (tan δ = 0.22 at 6.3 V) in a small radial package suitable for automotive and other temperature-challenging applications where long-term reliability and stable ripple performance are required.

Key Features

• Capacitance & Voltage — 330 µF capacitance with a 6.3 V rated voltage and ±20% tolerance, suited for bulk decoupling and energy storage in low-voltage DC circuits.
• Low Loss — Specified tan δ of 0.22 at 6.3 V (measurement frequency 120 Hz, 20°C), helping to minimize effective series losses in AC ripple conditions.
• Compact Radial Package — 6.3 mm diameter by 15 mm length can with 2.5 mm lead spacing; radial lead mounting for through-hole PCB layouts.
• Temperature Range — Rated for operation from −55°C to +105°C to support high-temperature environments.
• Reliability & Lifetime — AEC-Q200 rated with a specified lifetime of 2000 hours at 105°C for this part number.
• Ripple Current Performance — Ripple current ratings of 179.8 mA at 120 Hz and 310 mA at 200 kHz, enabling effective smoothing across low and high-frequency domains.
• Leakage Current Specification — After 1 minute at rated voltage and 20°C, leakage current is specified as not more than 0.03 × C × V (µA), aiding predictable bias current budgeting.
• Compliance — RoHS compliant for environmental regulatory alignment.

Typical Applications

• Automotive Electronics — Suitable for automotive modules where AEC-Q200 qualification and operation to +105°C are required for power supply filtering and decoupling.
• Power Supply Reservoirs — Used as bulk capacitance on low-voltage DC rails to stabilize voltage during transient loads.
• Embedded Control Boards — Compact radial form factor supports through-hole assemblies needing reliable smoothing and energy storage in constrained PCB areas.

Unique Advantages

• AEC-Q200 Qualification: Provides an explicit qualification rating for use in automotive-grade designs where component-level robustness is required.
• High Capacitance in Small Footprint: 330 µF in a 6.3 mm × 15 mm can helps minimize board area while maintaining required bulk capacitance.
• Wide Operating Temperature: −55°C to +105°C rating ensures stable performance across typical automotive and industrial thermal ranges.
• Measured Ripple Performance: Specified ripple currents at both low (120 Hz) and high (200 kHz) frequencies enable predictable thermal and lifetime planning.
• Predictable Leakage: Standardized leakage-current specification (0.03CV µA after 1 minute) simplifies design margins for standby and bias currents.
• RoHS Compliance: Meets environmental regulatory requirements for modern electronics manufacturing.
