UPJ1K390MPD6

The UPJ1K390MPD6 is an aluminum electrolytic capacitor in a radial lead can (φ10 × 12.5 mm) designed for general-purpose power applications. As part of Nichicon's UPJ series, it delivers a low-impedance profile and is ideally suited for switching power supplies and related power-filtering tasks.

Key electrical characteristics include 39 µF capacitance at 80 V rated voltage, ±20% tolerance, low dissipation factor (tanδ 0.08), and a specified load-life endurance of 5000 hours at 105°C, making it appropriate for demanding thermal and ripple-current conditions.

Key Features

• Electrical Rating — 39 µF capacitance with an 80 V rated voltage and ±20% tolerance for stable bulk energy storage and decoupling.
• Low Loss / Low Impedance — Specified tanδ of 0.08 supports lower AC loss, helping reduce heating under AC ripple and improving ripple-handling performance.
• Leakage Current — Typical leakage current specified at 93.6 µA after initial voltage application, facilitating predictable standby and quiescent behavior.
• High-Temperature Endurance — Rated for 5000 hours of load life at +105°C (per UPJ series specifications), supporting sustained operation in elevated-temperature environments.
• Ripple Current Capability — Ripple current ratings include 79.05 mA at 120 Hz and 155 mA at 1 kHz, suitable for smoothing and filtering in switch-mode power applications.
• Package and Mounting — Radial lead can (φ10 × 12.5 mm) with 5 mm lead spacing, designed for through-hole, radial-lead mounting and bulk/no terminal forming supply formats.
• Operating Range and Compliance — Operating temperature range −55°C to +105°C and RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and 80 V rating help manage ripple and transient currents.
• DC-DC Converters — Input/output smoothing on converters operating up to the 80 V domain, benefiting from the capacitor's ripple-current capability.
• Industrial Power Rails — Power-supply decoupling and energy storage in industrial control equipment operating across −55°C to +105°C.

Unique Advantages

• Proven Endurance: 5000-hour load-life rating at +105°C provides measurable reliability for sustained thermal stress.
• Low Dissipation Factor: tanδ 0.08 translates to lower AC losses and reduced self-heating under ripple conditions.
• Compact Radial Can: φ10 × 12.5 mm package with 5 mm lead spacing offers a compact through-hole form factor for tight layouts.
• Predictable Leakage: Specified leakage current (93.6 µA) aids in power budgeting and standby current estimates.
• RoHS Compliant: Meets RoHS directive requirements, simplifying environmental compliance for assemblies.
