UPS2A330MPD

The UPS2A330MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPS series, designed for compact power designs. It is a polarized, radial-lead capacitor with a 33 µF capacitance and a 100 V rated voltage, optimized for switching power supplies and general-purpose high-voltage decoupling.

Its combination of low impedance, small can size (φ10 × 12.5 mm), and wide operating temperature range makes it suitable where board space and stable performance under elevated temperature are important.

Key Features

• Electrical performance — 33 µF nominal capacitance with ±20% tolerance and a rated voltage of 100 V, providing stable charge storage for high-voltage rail decoupling.
• Low dissipation factor — tanδ = 0.08 measured at 20°C, 120 Hz, supporting efficient operation in AC and ripple environments.
• Low impedance — specified impedance of 460 mΩ, helping reduce voltage ripple and improve transient response in compact power stages.
• Ripple handling — low-frequency ripple current of 54.4 mA (120 Hz) and high-frequency ripple current of 320 mA (10 kHz), enabling effective smoothing across a range of switching frequencies.
• Thermal and lifetime rating — rated for operation from −55°C to 105°C with a guaranteed life of 2000 hours at 105°C.
• Mechanical footprint — radial lead, can-type package with φ10 × 12.5 mm dimensions, 5 mm lead spacing (±0.5 mm), suitable for through-hole mounting in compact assemblies.
• Leakage current — specified leakage current of 99 µA, measured after 1 minute at 20°C.
• Packaging and production — available in bulk (no terminal forming) and bag packing; product is in mass production. RoHS compliant.

Typical Applications

• Switching power supplies — output smoothing and decoupling in compact switching regulators, leveraging low impedance and high ripple capability.
• High-voltage general-purpose circuits — decoupling and energy storage on 100 V rails in industrial and laboratory power modules.
• Embedded power subsystems — compact through-hole option for designers needing reliable, high-voltage capacitors in space-constrained boards.

Unique Advantages

• Compact footprint with high voltage — φ10 × 12.5 mm can at 100 V lets designers place a 33 µF electrolytic in tight layouts without sacrificing voltage rating.
• Balance of low impedance and ripple capability — 460 mΩ impedance together with defined ripple currents at low and high frequency improves ripple attenuation across switching ranges.
• Wide temperature endurance — −55°C to 105°C operating range and 2000-hour life at 105°C support reliable operation in thermally demanding environments.
• Practical assembly form factor — radial leaded can with 5 mm lead spacing simplifies through-hole placement and mechanical retention on PCBs.
• Regulatory compliance — RoHS-compliant construction for use in regulated supply chains.
• Production readiness — part is in mass production and offered in standard bulk/bag packaging for volume procurement.
