UHW1J182MHD6

The UHW1J182MHD6 from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHW series designed for general-purpose electronic applications. It combines high capacitance with a compact φ18×35.5 mm can and is optimized for high ripple current and low impedance at higher frequencies.

This polarized capacitor is rated 1.8 mF at 63 V, offers a wide operating temperature range of –40°C to 105°C, and is manufactured to provide extended endurance (12,000 hours at 105°C).

Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) nominal capacitance with a rated voltage of 63 V and tolerance of ±20% (–20%~20%).
• Low Impedance, High Ripple Capability: Measured impedance of 63 mΩ and frequency-optimized ripple performance — 2.106 A at 120 Hz (low frequency) and 3.51 A at 10 kHz (high frequency).
• Dielectric Loss (tan δ): tan δ = 0.09 measured at 20°C and 120 Hz. (Datasheet notes: for capacitances >1000 μF, add 0.02 for every increase of 1000 μF.)
• Long Endurance: Rated for 12,000 hours at 105°C under specified DC bias plus rated ripple current, with recovery performance verified at 20°C.
• Leakage Current: Specified leakage current of 1,134 µA (after rated voltage and 2 minutes at 20°C as per test conditions).
• Package & Mounting: Radial lead can (φ18×35.5 mm) with 7.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Environmental Compliance: RoHS compliant.
• Status: Mass production availability.

Typical Applications

• General-purpose electronic circuits: Provides bulk capacitance for circuits that require stable energy storage and decoupling in a compact radial-lead can.
• High-ripple environments: Suited for locations in designs where elevated ripple currents occur, leveraging the part’s high ripple-current rating and low impedance.
• Thermally demanding assemblies: Applicable in applications that operate across –40°C to 105°C and require long endurance at elevated temperatures.

Unique Advantages

• High ripple current handling: 2.106 A at 120 Hz and 3.51 A at 10 kHz enable reliable operation where AC ripple stresses the capacitor.
• Compact, high-capacitance package: 1.8 mF in a φ18×35.5 mm can provides substantial bulk capacitance while conserving board space.
• Low impedance: 63 mΩ impedance supports improved transient response and reduced power loss in power-handling circuits.
• Long-term reliability: 12,000-hour endurance at 105°C supports extended operational life in high-temperature environments.
• Measured dielectric performance: tan δ specified at 0.09 (20°C, 120 Hz), with datasheet guidance for larger capacitances, aiding predictable AC loss budgeting.
• RoHS compliance and production-readiness: Environmentally compliant and available in mass production quantities with practical packaging options.
