UPJ2G2R2MPD

The UPJ2G2R2MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized can designed for general-purpose power electronics, with performance characteristics targeted at switching power supply applications.

This part delivers a 2.2 µF capacitance at a 400 V rating, with low impedance characteristics and an endurance rating up to 5000 hours at 105°C, making it suitable for designs that require compact high-voltage filtering and stable performance over extended elevated-temperature operation.

Key Features

• Electrical Rating — 2.2 µF nominal capacitance with a rated voltage of 400 V and capacitance tolerance of -20% to +20%.
• Low Loss — Dissipation factor (tan δ) specified at 0.25 (measured at 20°C, 120 Hz).
• Ripple Current Capability — Low-frequency ripple current of 28 mA (120 Hz) and high-frequency ripple current of 44.8 mA (200 kHz), enabling effective smoothing in power circuits.
• Leakage Current — Specified leakage current of 128 µA, supporting predictable standby and DC bias behavior.
• Long Endurance — Rated for 5000 hours of load life at 105°C, offering extended operational reliability for sustained thermal stress.
• Temperature Range — Operates from -40°C to +105°C to accommodate a wide envelope of ambient and board temperatures.
• Compact Radial Package — Metal can dimensions φ10 × 16 mm (diameter × length) with 5.0 mm lead spacing (±0.5 mm), delivered in bulk (no terminal forming) or bag packing for through-hole assembly.
• RoHS Compliant — Meets RoHS requirements as indicated in the product data.

Typical Applications

• Switching Power Supplies — Low impedance and endurance at 105°C make this part well suited for filtering and energy storage in switching regulators and power modules.
• Power Filtering and Decoupling — 400 V rating and controlled loss characteristics provide stable decoupling for high-voltage rails in power conversion circuits.
• High-Voltage Power Electronics — Compact 2.2 µF capacitance in a small radial can supports space-constrained designs that require elevated voltage handling.

Unique Advantages

• High Voltage Handling: 400 V nominal rating enables use on higher-voltage rails without upsizing the component.
• Extended High‑Temperature Life: Endurance specified to 5000 hours at 105°C provides predictable performance in thermally demanding environments.
• Low Impedance Design: Characterized for low loss (tan δ = 0.25 at 120 Hz) and measurable ripple current capability for effective smoothing in switching applications.
• Compact Through‑Hole Package: φ10 × 16 mm radial can with 5.0 mm lead spacing offers a small footprint for PCB layouts that require through-hole mounting.
• Controlled Leakage: Specified leakage current of 128 µA supports stable DC characteristics for power circuits and bias networks.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to suit different assembly and handling workflows.
