UPJ2A181MHD6

The UPJ2A181MHD6 is a radial-lead aluminum electrolytic capacitor with 180 µF capacitance rated at 100 V. It is part of Nichicon's UPJ series designed for low-impedance, long-life operation and is optimized for use in switching power supplies and general-purpose power filtering.

Key attributes include a wide operating temperature range of -55°C to 105°C, a 5000-hour endurance at 105°C, and through-hole radial packaging for robust board-level mounting and easy manual or wave solder assembly.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 100 V rated voltage for higher-voltage power rails.
• Tolerance — Capacitance tolerance of -20% to +20% (±20% at 120 Hz, 20°C) for predictable bulk energy storage.
• Low Dissipation Factor — tanδ (DF) of 0.08 measured at 20°C, 120 Hz and 100 V, indicating low losses under AC excitation conditions.
• High Ripple Current Capability — Rated ripple current of 381.24 mA at 120 Hz (low frequency) and 706 mA at 200 kHz (high frequency) to support switching and high-frequency supplies.
• Leakage Current — Specified leakage current of 540 µA for predictable standby and bias behavior.
• Long Endurance — 5000 hours rated life at 105°C, enabling sustained performance in thermally demanding applications.
• Wide Temperature Range — Operates from -55°C to 105°C for use across varied environmental conditions.
• Radial, Through-Hole Package — φ16 × 20 mm can with 7.5 mm lead spacing in a radial lead form factor; available in bulk or bag packing for flexible procurement.
• RoHS Compliant — Conforms to RoHS requirements for material compliance.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple handling at switching frequencies are required.
• Power Supply Filtering — Smoothing and decoupling on 100 V rails for industrial and commercial power electronics.
• Industrial Controls — Energy storage and filtering in control modules that demand wide temperature range and long life.
• General Purpose Electronics — Through-hole assemblies needing reliable capacitor performance for board-level power management.

Unique Advantages

• High-voltage capability: 100 V rating allows use on elevated DC rails without series stacking or complex topology changes.
• Low-loss operation: DF 0.08 at specified conditions reduces heat generation and improves efficiency in AC/ripple environments.
• Designed for high ripple: Significant ripple current ratings at both low and high frequencies support modern switching converters and high-frequency decoupling.
• Long thermal endurance: 5000-hour life at 105°C supports longevity in high-temperature applications and reduces maintenance frequency.
• Through-hole robustness: Radial lead construction with 7.5 mm lead spacing simplifies assembly for prototyping, repairable designs, and legacy equipment.
• Regulatory compliance: RoHS-compliant construction supports inclusion in regulated product lines without additional material qualification.
