UPJ1A392MHD

The UPJ1A392MHD is a radial lead aluminum electrolytic capacitor from Nichicon’s UPJ series designed for low-impedance power applications. It offers a capacitance of 3.9 mF (3900 µF) at a rated voltage of 10 V in a compact φ12.5 × 40 mm can with 5 mm lead spacing.

With a wide operating temperature range and a 5000-hour load life at 105°C, this part is targeted at general-purpose power filtering and switching power supply applications where high ripple capability and long-term reliability are required.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 10 V for bulk storage and decoupling in low-voltage power rails.
• Low Impedance Design — Specified low impedance construction for power-supply use; series-level documentation notes suitability for switching power supplies.
• High Ripple Current Capability — Low-frequency ripple 1.908 A (120 Hz) and high-frequency ripple 2.120 A (200 kHz) to support active power conversion and smoothing.
• Endurance — Rated for 5000 hours at 105°C (life/endurance) to maintain performance under continuous elevated-temperature load.
• Temperature Range — Operates from −55°C to +105°C to cover a broad set of environmental conditions.
• Electrical Loss and Leakage — Loss tangent (tan δ) measured at 0.23 (20°C, 120 Hz, 10 V) and leakage current specified at 1170 µA.
• Form Factor — Radial lead can, size φ12.5 × 40 mm, lead spacing 5 mm (±0.5 mm), suitable for through-hole PCB mounting.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) and bag packing. Product is in mass production.

Typical Applications

• Switching Power Supplies — Suited for output smoothing and energy storage in switch-mode power supplies, per UPJ series guidance.
• Power Supply Filtering — General-purpose filtering and decoupling on low-voltage power rails where high ripple handling is required.
• Industrial and Embedded Power Modules — Through-hole radial format supports use in compact power modules and embedded systems requiring robust long-life capacitors.

Unique Advantages

• Designed for High Ripple Loads: Rated ripple currents at both low and high frequencies (1.908 A at 120 Hz, 2.120 A at 200 kHz) reduce thermal stress in active power circuits.
• Long High-Temperature Lifetime: 5000-hour endurance at 105°C provides predictable performance over extended elevated-temperature operation.
• Broad Operating Range: −55°C to +105°C operation supports a wide set of environmental conditions without compromising capacitance.
• Compact Radial Package: φ12.5 × 40 mm can with 5 mm lead spacing offers a balance of capacitance density and through-hole PCB compatibility.
• Measurable Electrical Characteristics: Specified tan δ (0.23 at 20°C, 120 Hz, 10 V) and defined leakage current (1170 µA) enable straightforward thermal and loss budgeting in designs.
• Proven Series Platform: Part of Nichicon’s UPJ series, designed for low impedance and switching-power applications and produced at scale.
