UPJ1K181MHD6

The UPJ1K181MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, designed for general-purpose power applications. It delivers 180 µF capacitance at an 80 V rating in a compact φ16 × 15 mm can with a 7.5 mm lead spacing.

Built for high-temperature endurance and low impedance operation, this component is targeted at switching power supplies and other industrial power systems that require stable bulk capacitance, controlled leakage, and reliable long-term performance up to +105°C.

Key Features

• Capacitance & Voltage: 180 µF rated capacitance at 80 V suitable for bulk energy storage and filtering in power stages.
• Low Loss / Low Impedance: Specified tanδ of 0.08 supports lower AC loss and improved performance at operating frequencies.
• Leakage Current: Measured leakage current of 340.2 µA after voltage application (per product data) for predictable bias behavior.
• High-Temperature Endurance: Rated for 5000 hours at +105°C (per series specifications), providing extended life under elevated temperature and load.
• Ripple Current Capability: Rated ripple currents of 293.2 mA at 120 Hz and 543 mA at 1 kHz to support power supply ripple handling.
• Package & Mounting: Radial lead can (φ16 × 15 mm) with 7.5 mm lead spacing and polarized construction for through-hole PCB mounting.
• Operating Range: Wide ambient temperature range from -55°C to +105°C to cover demanding environmental conditions.
• Compliance & Packaging: RoHS-compliant; supplied in bulk/no terminal forming or bag packing for production environments.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where low impedance and high-temperature endurance improve voltage stability.
• Power Conversion Modules: Energy storage and ripple suppression in DC–DC converters and regulator output stages.
• Industrial Electronics: General-purpose filtering and decoupling in industrial power control and instrumentation that require extended life at elevated temperatures.

Unique Advantages

• High-Temperature Reliability: 5000-hour load life at +105°C provides predictable longevity in hot operating environments.
• Measured Low Loss: tanδ = 0.08 delivers reduced AC dissipation for improved efficiency in power circuits.
• Defined Leakage Performance: Documented leakage current value (340.2 µA) enables accurate bias and standby current budgeting.
• Clear Ripple Ratings: Specified ripple currents at 120 Hz and 1 kHz help designers size capacitors for real-world switching frequencies.
• Compact Through-Hole Form Factor: φ16 × 15 mm can with 7.5 mm lead spacing offers a space-efficient radial mounting option for PCB layouts.
• Production-Friendly Packaging: Bulk or bag packing options support volume assembly and handling preferences.
