UPJ1C392MHD

The UPJ1C392MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPJ series, offering 3.9 mF capacitance at a 16 V rating. It is designed for low-impedance operation and is well suited for power-supply filtering and general-purpose power applications.

Key electrical characteristics include a wide operating temperature range of -55°C to 105°C, a rated load life of 5000 hours at 105°C (series-level endurance), and RoHS compliance. The part is supplied in bulk or bag packing and is in mass production.

Key Features

• Capacitance & Tolerance — 3.9 mF (3900 µF) nominal capacitance with ±20% tolerance at 20°C, 120 Hz.
• Rated Voltage — 16 V DC rating suitable for common low-voltage power rails.
• Low Impedance, Switching PSU Focus — Part of Nichicon’s UPJ series specified for low impedance and intended for switching power supplies and related power-filtering duties.
• High Ripple Current Capability — Low-frequency ripple current 1.998 A (120 Hz) and high-frequency ripple current 2.22 A (200 kHz) to support bulk smoothing and high-frequency decoupling.
• Electrical Losses — Dissipation factor (tan δ) specified as 0.20 (measurement condition: 20°C, 120 Hz), enabling predictable AC loss behavior in design.
• Leakage Current — Specified leakage current of 1872 µA for initial condition reference.
• Robust Thermal Endurance — Rated for operation from -55°C to +105°C with a 5000-hour endurance at 105°C (series-level life rating noted in datasheet).
• Form Factor & Mounting — Radial lead can package, size φ16 × 30.5 mm length with 7.5 mm lead spacing (±0.5 mm), suitable for through-hole assemblies.
• Compliance & Availability — RoHS compliant and listed as mass production; packaged in bulk or bag formats.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and endurance at elevated temperature are required.
• DC–DC Converters — Input/output decoupling on converters benefiting from the part’s ripple-current handling and low-loss characteristics.
• Industrial Power Modules — Power-rail filtering in industrial electronics that operate across a wide temperature range and demand long life at elevated temperatures.
• Consumer Power Electronics — General-purpose power filtering and energy storage for consumer devices with through-hole mounting requirements.

Unique Advantages

• High Ripple Handling: Provides 1.998 A at 120 Hz and 2.22 A at 200 kHz to support both low-frequency bulk smoothing and high-frequency decoupling.
• Long Thermal Endurance: Specified 5000 hours at 105°C (series-level endurance) for designs that must withstand prolonged elevated-temperature operation.
• Low-Impedance Design: UPJ series specification for low impedance supports tighter voltage regulation and reduced output ripple in power supplies.
• Predictable AC Performance: tan δ specified at 0.20 (20°C, 120 Hz) and defined leakage current for reliable loss and standby current budgeting.
• Practical Through-Hole Form Factor: φ16 × 30.5 mm radial can with 7.5 mm lead spacing simplifies placement and replacement in through-hole assemblies.
• Regulatory Compliance & Production Ready: RoHS compliant and available in mass production with bulk or bag packing options for volume assembly.
