UHW1K182MHD

The UHW1K182MHD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in the UHW series. It is a radial-lead, polarized capacitor specified at 1.8 mF (1800 µF) and 80 V, designed for general-purpose applications that require high ripple current capability and reliable long-term performance.

Key attributes include low impedance at higher frequencies, high rated ripple currents, a wide operating temperature range of −40°C to 105°C, and an endurance rating of 12,000 hours at 105°C — all in a compact φ18 × 40 mm can with 7.5 mm lead spacing.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C; rated for 80 V DC.
• High Ripple Current — Low-frequency ripple current of 2.316 A at 120 Hz and high-frequency ripple current of 3.86 A at 10 kHz, supporting demanding ripple conditions.
• Low Impedance & Loss — Series impedance listed as 76 mΩ and tan δ of 0.09 (120 Hz, 20°C) for reduced AC loss and improved filtering at frequency.
• Long Endurance — Rated life of 12,000 hours at 105°C under specified DC bias and ripple conditions, with controlled capacitance and leakage characteristics after endurance testing.
• Wide Temperature Range — Operates from −40°C to 105°C for stable performance across typical industrial and commercial environments.
• Radial Lead Package — φ18 × 40 mm can with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Leakage & Tolerance — Product-specific leakage current 1440 µA and capacitance tolerance of −20% to +20% at 120 Hz, 20°C.
• Regulatory Status — RoHS compliant; product is in mass production.

Typical Applications

• General-purpose electronics — Suitable where a polarized, high-capacitance, radial-lead aluminum electrolytic capacitor is required for general-purpose use.
• Power filtering and decoupling — Low impedance and high ripple current capability support AC ripple suppression and smoothing tasks in power circuits.
• Energy storage in compact designs — Miniature φ18 × 40 mm can allows higher capacitance in a small footprint while maintaining long-term endurance.

Unique Advantages

• High ripple current handling: Rated for 2.316 A at 120 Hz and 3.86 A at 10 kHz, enabling reliable operation under significant AC stress.
• Low impedance at frequency: 76 mΩ series impedance and tan δ of 0.09 help reduce AC losses and improve filtering effectiveness.
• Extended high-temperature life: 12,000 hours at 105°C provides predictable long-term performance in elevated-temperature environments.
• Compact radial-lead form factor: φ18 × 40 mm can with 7.5 mm lead spacing fits applications that require a smaller case while keeping high capacitance.
• Wide operating temperature range: −40°C to 105°C supports deployment across a broad range of environmental conditions.
• RoHS compliant and production-ready: Meets RoHS requirements and is available in mass production quantities with packaging options to suit assembly processes.
