UHW1V182MHD6

The UHW1V182MHD6 is a polarized aluminum electrolytic capacitor in a radial lead can form, offered in Nichicon’s UHW series. It provides 1800 µF capacitance at a 35 V rating in a compact φ16 × 25 mm can with 7.5 mm lead spacing for through‑hole mounting.

Designed for general-purpose power electronics, this part delivers high ripple current capability, low impedance at higher frequencies, and a long endurance rating for sustained operation up to 105°C—making it suited to smoothing, decoupling and energy‑storage roles in embedded and industrial designs.

Key Features

• Capacitance & Voltage: 1800 µF nominal capacitance with a rated voltage of 35 V and tolerance of -20% to +20%.
• Low Impedance: Measured impedance of 39 mΩ supports lower voltage ripple and improved performance in high‑frequency environments.
• High Ripple Current: Rated low‑frequency ripple current of 2.286 A at 120 Hz and high‑frequency ripple current of 3.81 A at 10 kHz, supporting switching and power conversion applications.
• Electrical Losses: Tangent of loss angle (tan δ) = 0.11 measured at 20°C, 120 Hz, indicating controlled dielectric losses for this capacitance and voltage class.
• Leakage Current: Specified leakage current of 630 µA, enabling predictable bias behavior after voltage application.
• High‑Temperature Endurance: Rated life of 10,000 hours at 105°C for the 10–50 V class, supporting extended operation under elevated temperature stress.
• Form Factor & Mounting: Radial lead can, package size φ16 × 25 mm (L: 2.5 × D: 1.6 cm) with 7.5 mm lead spacing (±0.5 mm) for through‑hole assembly; available in bulk or bag packing.
• Environmental Compliance: RoHS compliant.

Typical Applications

• Switch‑mode power supplies: Bulk smoothing and output filtering where high ripple current and low impedance improve voltage stability.
• DC/DC converters: Decoupling and energy buffering for high‑frequency switching stages using the part’s high‑frequency ripple capability.
• Industrial power electronics: Energy storage and smoothing in embedded control and industrial equipment operating up to 105°C.
• General‑purpose power filtering: Through‑hole, serviceable capacitor for boards requiring robust electrolytic capacitance and predictable long‑term endurance.

Unique Advantages

• High ripple handling: Combines 2.286 A at 120 Hz and 3.81 A at 10 kHz ripple ratings to support both low‑ and high‑frequency power circuits.
• Compact radial can: φ16 × 25 mm size delivers 1800 µF in a small footprint for space‑constrained through‑hole designs.
• Low impedance: 39 mΩ impedance helps reduce voltage ripple and improve transient response in power rails.
• Long life at elevated temperature: 10,000 hours endurance at 105°C for the 10–50 V class provides predictable life in hot operating environments.
• Predictable electrical characteristics: Specified tan δ (0.11 at 20°C, 120 Hz) and defined leakage current (630 µA) simplify design verification and reliability planning.
• RoHS compliance and packaging options: Environmentally compliant and available in bulk or bag packing for production or prototype needs.
