UPJ2A820MPD

The UPJ2A820MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series, configured in a radial-lead can. It delivers low impedance and robust endurance for power applications, making it suitable for switching power supplies and general-purpose power filtering where long life and stable performance at elevated temperature are required.

Key Features

• Capacitance & Voltage: 82 µF rated at 100 V for energy storage and smoothing in higher-voltage circuits.
• High-temperature endurance: Rated for 5000 hours at 105°C under DC bias plus rated ripple current (φ10 case), supporting prolonged operation in hot environments.
• Low dissipation factor: tanδ = 0.08 (measured at 20°C, 120 Hz), indicating low loss and efficient performance in AC/ripple conditions.
• Ripple current capability: Low-frequency ripple current 200.72 mA at 120 Hz and high-frequency ripple current 386 mA at 200 kHz, enabling reliable ripple handling across frequencies.
• Leakage current: Specified leakage current of 246 µA, suitable for power supply and decoupling applications where controlled leakage is required.
• Compact radial can: Mechanical size φ10 × 30.5 mm (L) with 5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies.
• Packaging & production status: Available in bulk (no terminal forming) and bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Switching Power Supplies — Smoothing and filtering of output rails where low impedance and long-life operation at elevated temperature are needed.
• Power Converters — Bulk smoothing and decoupling in DC–DC converters and intermediate bus circuits operating up to 100 V.
• General-purpose Power Filtering — Decoupling and ripple reduction in a variety of general-purpose electronic and industrial power designs.

Unique Advantages

• Proven high-temperature life: 5000-hour endurance at 105°C (φ10 case) gives designers confidence for sustained thermal stress environments.
• Low-loss performance: tanδ of 0.08 at 20°C/120 Hz reduces internal heating and improves efficiency under AC ripple conditions.
• Broad ripple handling: Specified ripple currents at both low and high frequencies support mixed-frequency applications common in modern power electronics.
• High-voltage capability in a small footprint: 100 V rating in a φ10 × 30.5 mm can enables compact designs that still require higher DC voltage handling.
• Manufacturing-ready packaging: Bulk and bag packing options simplify procurement for production and prototyping workflows.
• Regulatory compliance: RoHS compliant to support designs targeting restricted-substance requirements.
