UPJ2A390MPD6

The UPJ2A390MPD6 is a radial-lead aluminum electrolytic capacitor designed for general-purpose and power electronic applications, with performance characteristics targeted at switching power supplies. It combines a 39 µF capacitance with a 100 V rated voltage in a compact radial can (φ10 × 16L) for use where high-voltage bulk capacitance and low impedance are required.

Key value propositions include low impedance behavior (tanδ 0.08 at 20°C, 120 Hz), defined ripple current capability at both low and high frequencies, and extended endurance of 5000 hours at 105°C for sustained reliability in demanding environments.

Key Features

• Capacitance & Rated Voltage — 39 µF nominal capacitance with a rated voltage of 100 V and capacitance tolerance of −20% to +20%.
• Low Impedance Performance — Tangent of loss angle (tanδ) of 0.08 measured at 20°C, 120 Hz, supporting efficient energy smoothing in power circuits.
• Ripple Current Capability — Specified ripple current of 98.43 mA at 120 Hz and 193 mA at 1 kHz, enabling filtering and decoupling across typical power frequencies.
• Leakage Current — Rated leakage current of 117 µA for predictable steady-state behavior after voltage application.
• Long Endurance — Rated for 5000 hours of load life at 105°C, providing long-term stability in elevated-temperature applications.
• Radial Mounting & Mechanical — Radial-lead can with dimensions φ10 × 16L, lead spacing 5 mm (±0.5 mm), and polarized construction for through-hole mounting.
• Packaging & Compliance — Available in bulk (no terminal forming) or bag packing and RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling at up to 100 V, leveraging low impedance and specified ripple current performance.
• Industrial Power Modules — DC bus smoothing and energy storage in industrial power electronics that require extended endurance at elevated temperatures.
• General-Purpose High-Voltage Filtering — Through-hole designs needing compact high-voltage capacitance and predictable leakage characteristics.

Unique Advantages

• 100 V Rated Voltage: Enables use in higher-voltage rails without series stacking or additional derating.
• Low Loss Angle (tanδ = 0.08): Contributes to lower internal heating and effective AC filtering at 120 Hz measurement conditions.
• Dual-Frequency Ripple Data: Specified ripple currents at both 120 Hz and 1 kHz help designers size capacitors for real-world power-frequency and switching conditions.
• Designed for Long Life at Elevated Temperature: 5000 hours at 105°C supports reliable operation in thermally demanding systems.
• Compact Radial Package: φ10 × 16L with 5 mm lead spacing provides a space-efficient through-hole solution for retrofit or board-level power designs.
• RoHS Compliant and Flexible Packing: Conforms to RoHS; available in bulk or bag packing to suit assembly workflow needs.
