URS1A332MHD

The URS1A332MHD is a Nichicon URS series aluminum electrolytic capacitor in a radial-lead, low-profile can package. It provides 3.3 mF (3300 µF) capacitance at a 10 V rating with a compact φ16 × 15 mm form factor and 7.5 mm lead spacing.

Designed for general-purpose electronic applications, the part balances high capacitance and defined ripple-current capability with long endurance characteristics, making it suitable where board-space efficiency and reliable bulk energy storage are required.

Key Features

• High Capacitance — 3.3 mF (3300 µF) nominal capacitance with ±20% tolerance for bulk energy storage and smoothing in low-voltage circuits.
• 10 V Rated Voltage — Specified for 10 V systems, providing appropriate margin for low-voltage power rails.
• Radial Lead, Compact Package — φ16 × 15 mm can with 7.5 mm lead spacing; radial-lead mounting for through-hole designs.
• Ripple Current Capability — Low-frequency ripple current 1.3 A (120 Hz) and high-frequency ripple current 1.495 A (10 kHz) to support dynamic load conditions.
• Endurance — Rated lifetime of 2000 hours at 85°C, meeting the URS series endurance specification for extended operation at elevated temperature.
• Wide Operating Temperature — Specified for use from −40°C to +85°C.
• Leakage Current — Specified leakage current of 990 µA to help quantify standby and quiescent losses.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to suit different production workflows.

Typical Applications

• General-purpose electronic equipment — Bulk energy storage and smoothing for low-voltage power rails in compact assemblies.
• Power supply decoupling — Local bulk capacitance near regulators or DC/DC converters to support transient loads.
• Embedded and consumer devices — Space-efficient through-hole mounting where a compact, high-capacitance solution is needed.

Unique Advantages

• High capacitance in a compact footprint: 3300 µF in a φ16 × 15 mm can enables significant bulk capacitance without a large board area impact.
• Quantified ripple performance: Ripple-current ratings at 120 Hz and 10 kHz let designers size capacitors for both low- and high-frequency ripple conditions.
• Defined thermal endurance: 2000 hours at 85°C provides a clear reference for lifetime expectations in elevated-temperature environments.
• Through-hole radial mounting: Simple radial-lead mounting and 7.5 mm lead spacing ease placement and soldering for manual and automated assembly.
• Practical leakage specification: Leakage current value (990 µA) supports power-budgeting and standby-loss calculations.
