UPJ2A181MHD

The UPJ2A181MHD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial‑lead can intended for power electronics. It delivers 180 μF at 100 V in a compact φ12.5 × 30.5 mm package with 5 mm lead spacing.

Designed for low impedance and long life under load, this capacitor is well suited for switching power supplies and general‑purpose power filtering where elevated temperature endurance and reliable ripple handling are required.

Key Features

• Capacitance and Voltage: 180 μF nominal capacitance with ±20% tolerance, rated at 100 V DC.
• Low loss (tan δ): tanδ ≤ 0.08 measured at 20°C, 120 Hz, supporting efficient energy handling with reduced dissipation.
• Ripple handling: Low‑frequency ripple current 346.14 mA at 120 Hz and high‑frequency ripple current 641 mA at 200 kHz for improved performance in switched and high‑frequency circuits.
• Leakage current: Specified leakage current 540 μA after rated voltage application, enabling predictable bias behavior.
• High temperature endurance: Rated for 5,000 hours of load life at 105°C (series endurance characteristic), supporting sustained operation in hot environments.
• Operating temperature range: −55°C to +105°C to cover a wide range of industrial operating conditions.
• Package and mounting: Radial lead can, polarized, size φ12.5 × 30.5 mm with 5.0 mm lead spacing (±0.5 mm), available in bulk/no terminal forming or bag packing.
• Environmental compliance: RoHS compliant.

Typical Applications

• Switching power supplies: Low impedance and rated ripple currents make this capacitor suitable for output and bulk filtering in SMPS designs.
• DC‑DC converters and power modules: Provides bulk capacitance and ripple smoothing where compact size and high voltage rating are needed.
• Industrial control equipment: Supports reliable filtering and energy buffering in industrial power systems operating across a wide temperature range.
• General‑purpose electronic equipment: Polarized radial package fits through‑hole assemblies for power filtering and decoupling in a variety of products.

Unique Advantages

• Long load life at elevated temperature: 5,000 hours at 105°C provides predictable long‑term performance in thermally demanding applications.
• Measured low loss: tanδ of 0.08 (20°C, 120 Hz) reduces heat generation and energy dissipation in power paths.
• High voltage capability in a compact can: 100 V rating with a φ12.5 × 30.5 mm footprint delivers significant capacitance where board space is constrained.
• Designed for switching environments: Series emphasis on low impedance and explicit ripple current specifications for both low and high frequencies helps designers size filters with confidence.
• Clear mechanical footprint: Radial leads with 5.0 mm spacing and specified lead tolerance simplify through‑hole assembly and mechanical planning.
• Regulatory compliance: RoHS compliance supports use in regulated product lines.
