UPJ1C392MHD6

The UPJ1C392MHD6 is a high-reliability miniature aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized can-type capacitor specified for 16 V operation with 3,900 µF nominal capacitance and ±20% tolerance.

Designed for power filtering and bulk energy storage in compact power designs, this UPJ part combines high ripple-handling capability with extended endurance, making it suitable for switching power supplies and other general-purpose power applications that require long life at elevated temperature.

Key Features

• Capacitance and voltage: 3.9 mF (3,900 µF) nominal capacitance at a rated voltage of 16 V, with capacitance tolerance of -20% to +20%.
• Low dissipation factor: tanδ (DF) = 0.2 measured at 20°C, 120 Hz, indicating controlled losses for power-frequency operation.
• High ripple-current capability: Low-frequency ripple current of 1.854 A at 120 Hz and high-frequency ripple current of 2.06 A at 200 kHz, supporting bulk smoothing and decoupling in switching supplies.
• Leakage current: Specified leakage current of 1,872 µA (calculated per C·V basis for this part), suitable for power applications where defined leakage limits are required.
• Long endurance at elevated temperature: Rated for 5,000 hours life at +105°C when used under specified conditions (UPJ series endurance specification).
• Compact radial package: Aluminum can with dimensions Ø18 × 25 mm (D × L), radial lead mounting and 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Wide operating temperature range: Specified from -55°C to +105°C for use across a broad set of environments.
• RoHS compliant: Meets RoHS directive requirements referenced in the product documentation.

Typical Applications

• Switching power supplies: Bulk smoothing and output filtering where high ripple current capability and long life at 105°C are required.
• DC power rails and converters: Energy storage and decoupling on intermediate and output rails for compact power modules and board-level converters.
• Industrial power electronics: Filtering and transient buffering in industrial controllers and power assemblies operating over -55°C to +105°C.

Unique Advantages

• Extended high-temperature endurance: 5,000 hours at +105°C supports reliable operation in thermally demanding power designs.
• Robust ripple handling: Specified ripple currents at both low and high frequency allow the capacitor to perform across switching and ripple spectra typical of modern supplies.
• Clear electrical limits: Defined leakage current (1,872 µA) and tanδ (0.2) measurements provide predictable behavior for margin and thermal design.
• Space-efficient radial can: Ø18 × 25 mm footprint with 7.5 mm lead spacing offers a compact solution for through-hole PCB layouts.
• Series-level low-impedance design: UPJ series characteristics emphasize low impedance for switching supply applications, aiding transient response and ripple reduction.
• Regulatory compliance: RoHS compliance supports use in designs targeting restricted-substance requirements.
