UHD1V182MHD

The UHD1V182MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHD series, offering 1800 µF capacitance at a 35 V rating in a compact φ16 × 25 mm can. It is a general-purpose, polarized electrolytic designed for applications that require high ripple handling and low impedance across a wide temperature range.

Built for heavy-duty smoothing and decoupling needs, this part delivers high ripple current capability and extended endurance for long-term operation up to 105°C.

Key Features

• High Capacitance: 1.8 mF (1800 µF) for significant bulk energy storage in compact assemblies.
• Rated Voltage: 35 V working voltage suitable for many power rail and supply applications.
• Low Impedance / High Ripple Handling: UHD series characteristics include lower impedance at high frequency and high ripple current; this part supports 2.768 A at 120 Hz and 3.46 A at 100 kHz.
• Loss Characteristics: tan δ = 0.12 measured at 20°C, 120 Hz, providing predictable AC loss behavior for design margin calculations.
• Reliability & Endurance: Rated for 5000 hours at 105°C, supporting long-term operation in elevated-temperature environments.
• Mechanical & Mounting: Radial lead mounting with 7.5 mm lead spacing (±0.5 mm) and a φ16 × 25 mm package (lead spacing and dimensions per part data).
• Leakage Current: Low leakage current specified at 630 µA (after 2 minutes at rated voltage, 20°C), aiding low-standby-loss designs.
• Packaging Options & Production Status: Available in Bulk (No Terminal Forming) or Bag Packing; status: Mass Production.
• Environmental Compliance: RoHS compliant.

Typical Applications

• Power Supply Bulk Filtering: High capacitance and high ripple current capability make it suitable for smoothing and bulk energy storage on DC rails.
• Switching Regulator Output: Low impedance and predictable tan δ at 120 Hz help reduce output voltage ripple in switching power supplies and converters.
• Industrial & Consumer Electronics: General-purpose decoupling and energy storage where operation up to 105°C and long endurance are required.

Unique Advantages

• Compact Energy Density: 1800 µF in a φ16 × 25 mm can enables smaller board footprint while retaining significant capacitance.
• High Ripple Endurance: Specified ripple current of 2.768 A (120 Hz) and 3.46 A (100 kHz) supports demanding AC stress in power stages.
• Long Life at Elevated Temperature: 5000 hours rated life at 105°C gives designers confidence for sustained high-temperature use.
• Predictable Electrical Losses: tan δ = 0.12 at 20°C, 120 Hz helps quantify dissipation and thermal planning in designs.
• Low Leakage: 630 µA leakage supports lower standby losses and predictable behavior after applied voltage.
• Procurement-Ready Packaging: Bulk and bag packing options simplify inventory and assembly planning for production volumes.
