UPS1C331MPD

The UPS1C331MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power applications. Built for compact switching power supplies and board-level power filtering, it combines a 330 µF capacitance with a 16 V rating in a φ8 × 11.5 mm package.

Engineered for extended operation across a wide temperature range, this polarized capacitor delivers low impedance and measurable ripple-current capability for both low- and high-frequency power conditioning tasks.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20% for predictable bulk energy storage.
• Low Impedance — Rated impedance of 280 mΩ (20°C/100 kHz) to support efficient ripple suppression in compact power designs.
• Ripple Current Capability — Low-frequency ripple current 291.1 mA (120 Hz) and high-frequency ripple current 410 mA (10 kHz) to handle switching supply ripple across common frequency ranges.
• Loss Angle (tan δ) — tan δ of 0.16 (measured at 20°C, 120 Hz) for predictable dissipation characteristics.
• Temperature and Endurance — Operating range −55°C to +105°C with rated endurance of 2000 hours at 105°C, suitable for sustained elevated-temperature operation.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole assembly and bulk/bag packing options.
• Leakage Current — Specified leakage current of 158.4 µA (measured per datasheet conditions), enabling predictable standby loss.
• RoHS Compliant — Meets RoHS requirements for material compliance.

Typical Applications

• Switching Power Supplies — Compact decoupling and bulk storage for board-level switching regulators where low impedance and small size are required.
• General Purpose Power Filtering — Smoothing and ripple reduction on DC rails in consumer and industrial electronic assemblies.
• Embedded Systems — Local energy reservoir and transient absorption for microcontroller and peripheral power domains in compact systems.

Unique Advantages

• Space-efficient energy storage: 330 µF in a φ8 × 11.5 mm can provides significant capacitance in a small footprint for dense PCB layouts.
• Measurable ripple handling: Distinct low- and high-frequency ripple current ratings (291.1 mA at 120 Hz, 410 mA at 10 kHz) allow designers to size capacitors against expected switching frequencies.
• Wide temperature endurance: −55°C to +105°C rating and 2000-hour endurance at 105°C support reliable performance in elevated-temperature environments.
• Predictable electrical characteristics: Specified impedance (280 mΩ) and tan δ (0.16) simplify thermal and loss budgeting in power designs.
• Through-hole convenience: Radial lead package with standard lead spacing simplifies prototype and production assembly without special handling.
• Regulatory readiness: RoHS compliance eases selection for designs requiring lead-free material compliance.
