UHW1J181MPD6

The UHW1J181MPD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series designed for high ripple current and long-term reliability. It provides 180 µF capacitance at a 63 V rating in a compact φ8 × 20 mm can with radial leads and 3.5 mm lead spacing.

Engineered for general-purpose electronic equipment, this capacitor combines low impedance at higher frequencies, a wide operating temperature range of −40°C to +105°C, and a rated endurance of 11,000 hours at 105°C to support robust power-filtering and decoupling needs in space-constrained designs.

Key Features

• Capacitance and Voltage: 180 µF nominal capacitance with a 63 V rated voltage and capacitance tolerance of −20% to +20% for predictable energy storage.
• Low Impedance and Loss: Rated impedance of 660 mΩ and tan δ of 0.09 (measured at 20°C, 120 Hz) for reduced AC loss and improved performance at frequency.
• High Ripple Current Capability: Low-frequency ripple current of 632 mA (120 Hz) and high-frequency ripple current of 1.58 A (10 kHz), supported by lower impedance at high frequency in the UHW series.
• Reliability and Lifetime: Endurance specified at 11,000 hours at 105°C; leakage current listed as 113.4 µA and defined end-of-life electrical limits in the UHW series endurance specification.
• Compact Radial Package: φ8 × 20 mm aluminum can with radial lead mounting (lead spacing 3.5 mm, lead diameter 0.6 mm for φ8 case), available in bulk or bag packing and offered in mass production.
• Operating Range and Compliance: Operates from −40°C to +105°C and is RoHS compliant.

Typical Applications

• General-Purpose Power Filtering: Suited for smoothing and bulk decoupling in general-purpose electronic equipment where compact size and high ripple handling are required.
• Power Supply Decoupling: Compact radial form factor supports decoupling at output stages and local supply nodes in space-constrained boards.
• High-Frequency Ripple Management: Lower impedance at higher frequencies and specified high-frequency ripple current (1.58 A at 10 kHz) make it applicable where AC ripple performance matters.

Unique Advantages

• Compact footprint with robust capacitance: 180 µF in a φ8 × 20 mm can enables designers to save board space without sacrificing energy storage.
• High ripple tolerance at multiple frequencies: Specified ripple currents at 120 Hz and 10 kHz, plus UHW-series low impedance at high frequency, support reliable AC stress handling.
• Long endurance at elevated temperature: 11,000-hour rating at 105°C provides a predictable lifetime metric for thermal-stressed designs.
• Clear, verifiable electricals: Defined impedance (660 mΩ), tan δ (0.09), and leakage current (113.4 µA) enable accurate simulation and reliability planning.
• Standard radial mounting: 3.5 mm lead spacing and 0.6 mm lead diameter (φ8 case) simplify through-hole assembly and mechanical retention for wave or manual insertion processes.
• Regulatory compliance: RoHS compliance supports integration into designs targeting restricted-substance requirements.
