UPJ2A180MED

The UPJ2A180MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized capacitor rated for 100 V with a nominal capacitance of 180 µF and a compact φ6.3 × 15 mm can size.

Designed as part of the UPJ low-impedance family, this component targets power-filtering and energy-storage roles in general-purpose electronic designs, offering a broad operating temperature range and measurable ripple-handling characteristics.

Key Features

• Electrical Rating — Rated voltage 100 V and nominal capacitance 180 µF with tolerance ±20% for dependable DC energy storage.
• Low Loss — Tangent of loss angle (tanδ) 0.08 measured at 20°C, 120 Hz, supporting efficient operation in filtering and smoothing applications.
• Ripple Performance — Low-frequency ripple current 40 mA at 120 Hz and high-frequency ripple current 80 mA at 200 kHz for combined AC stress capability.
• Leakage Current — Specified leakage current of 54 µA, enabling predictable bias behavior in precision circuits.
• Thermal and Lifetime — Operating temperature range −55°C to +105°C with an endurance rating of 2000 hours at 105°C.
• Mechanical and Packaging — Radial lead package (φ6.3 × 15 mm), lead spacing 2.5 mm (±0.5 mm), supplied in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — As part of the UPJ series described as low impedance, this capacitor suits output filtering and smoothing in switch-mode power supplies.
• Power Filtering — Used for decoupling and ripple attenuation on intermediate rails and DC bus circuits where 100 V rating and compact size are required.
• General-Purpose Electronics — Applicable to a wide range of general-purpose board-level power designs requiring polarized bulk capacitance in a radial-lead form factor.

Unique Advantages

• High Voltage Capability: 100 V rating provides margin for higher-voltage rails and allows usage in a variety of power architectures.
• Compact Footprint: φ6.3 × 15 mm can size with 2.5 mm lead spacing delivers substantial capacitance in a small radial package for space-constrained designs.
• Measured Ripple Ratings: Specified low- and high-frequency ripple currents enable designers to account for AC stress across frequencies.
• Predictable Loss and Leakage: Low tanδ (0.08 at 120 Hz) and defined leakage current (54 µA) simplify thermal and bias budgeting in circuits.
• Wide Temperature Range: −55°C to +105°C rating supports operation across harsh environmental conditions encountered in industrial and embedded systems.
• RoHS Compliant: Meets RoHS directives for designs requiring restricted-substance compliance.
