URS1V331MPD

The URS1V331MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s URS series. It delivers 330 µF capacitance at a 35 V rating in a compact φ10 × 12.5 mm can with a 5.0 mm lead spacing, intended for general-purpose circuit use.

Designed for board-level smoothing and energy storage where a low-profile, through-hole radial capacitor is required, this part combines a wide operating temperature range (−40 °C to 85 °C) with defined endurance and ripple-handling characteristics for reliable performance in general-purpose electronic assemblies.

Key Features

• Electrical Rating: 330 µF capacitance with a 35 V rated voltage and capacitance tolerance of ±20% (−20%~20%), providing predictable bulk capacitance for power supply and filtering applications.
• Low-profile, radial package: Compact φ10 × 12.5 mm can with 5.0 mm lead spacing and radial lead mounting type, suitable for through-hole PCB layouts requiring a small footprint.
• Temperature and endurance: Operating temperature range −40 °C to 85 °C with an endurance rating of 2000 hours at 85 °C, enabling sustained operation under elevated temperature conditions specified by the datasheet.
• Ripple current capability: Low-frequency ripple current 480 mA at 120 Hz and high-frequency ripple current 720 mA at 10 kHz, supporting ripple handling across common supply frequencies.
• Loss and leakage characteristics: Tangent of loss angle (tan δ) 0.14 measured at 20 °C, 120 Hz, and measured leakage current given as 346.5 µA, enabling designers to evaluate dissipation and leakage budgets precisely.
• Packaging options: Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• General-purpose power filtering: Bulk capacitance and 35 V rating make the URS1V331MPD suitable for smoothing and energy storage on power rails in general-purpose electronics.
• Through-hole PCB designs: Radial-lead form factor with 5.0 mm lead spacing fits compact through-hole layouts where a low-profile electrolytic capacitor is required.
• Temperature-challenged assemblies: Use in systems operating between −40 °C and 85 °C where defined endurance (2000 h at 85 °C) is required for lifecycle planning.

Unique Advantages

• Compact footprint: φ10 × 12.5 mm can provides substantial capacitance in a small, low-profile package to save board area and fit constrained enclosures.
• Clear ripple specifications: Specified ripple currents at both 120 Hz and 10 kHz allow engineers to size capacitors against real operating frequencies and thermal constraints.
• Endurance-backed performance: Rated for 2000 hours at 85 °C with post-test limits defined for capacitance, tan δ and leakage, supporting predictable long-term behavior.
• Easy procurement and handling: Offered in bulk or bag packing to support prototyping and production workflows without unnecessary repackaging.
• Through-hole mounting simplicity: Radial lead design and standard 5.0 mm lead spacing simplify insertion and soldering for manual and automated through-hole assembly processes.
