UPJ2A330MPD

The UPJ2A330MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, specified at 33 µF and 100 V with ±20% tolerance. It is a low-impedance, polarized can-style capacitor designed specifically for switching power supply and general-purpose power-filtering applications.

Key electrical and mechanical attributes include a low loss tangent (tanδ 0.08 at 20°C, 120 Hz), rated ripple current figures for both low and high frequency, a compact φ8 × 15 mm package with 3.5 mm lead spacing, and an endurance rating of 3000 hours at 105°C for the φ8 case size.

Key Features

• Capacitance & Voltage: 33 µF nominal capacitance at a 100 V rated voltage with ±20% tolerance, suitable for medium-voltage smoothing and decoupling.
• Low Impedance / Low Loss: Specified tanδ of 0.08 (measured at 20°C, 120 Hz) to help reduce AC losses in power circuits.
• Defined Ripple Handling: Low-frequency ripple current 84.5 mA (120 Hz) and high-frequency ripple current 169 mA (200 kHz) for effective ripple suppression across frequency ranges.
• Leakage Current: Specified leakage current of 99 µA, enabling predictable bias behavior after voltage application.
• Endurance: Rated for 3000 hours at 105°C (φ8 case), supporting sustained operation in elevated-temperature environments.
• Package & Mounting: Radial lead can (φ8 × 15 mm) with 3.5 mm lead spacing and 0.5 mm spacing tolerance for through-hole mounting and straightforward assembly.
• Operating Temperature Range: −55°C to +105°C, covering a wide range of industrial and commercial environments.
• RoHS Compliant: Environmentally compliant manufacturing per the product data.
• Packaging Options: Available in bulk (no terminal forming) and bag packing for flexible procurement and handling.

Typical Applications

• Switching Power Supplies: Use as output smoothing and bulk filtering where low impedance and defined ripple performance at both low and high frequencies are required.
• General-Purpose Power Filtering: Suitable for board-level decoupling and energy storage in industrial and consumer electronic power circuits.
• Compact Through-Hole Assemblies: The φ8 × 15 mm radial can and 3.5 mm lead spacing make it a fit for compact PCB footprints requiring through-hole components.

Unique Advantages

• Predictable AC performance: Low tanδ (0.08 at 20°C, 120 Hz) and specified ripple currents give designers measurable parameters to manage thermal and ripple budgets.
• High voltage capability: 100 V rating enables use in higher-voltage power rails without changing capacitor family.
• Thermal endurance: 3000-hour rating at 105°C (φ8) supports longer field life in elevated-temperature applications.
• Compact radial form factor: φ8 × 15 mm can and standard 3.5 mm lead spacing simplify retrofits or designs that need a small through-hole electrolytic.
• Controlled leakage: Specified leakage current (99 µA) aids predictable startup and standby current calculations.
• Regulatory compliance: RoHS-compliant construction aligns with common environmental requirements.
