UHE1V182MHD3

The UHE1V182MHD3 is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UHE series, offering low impedance and high reliability in a compact can package. Designed for general‑purpose smoothing, decoupling and energy storage, it targets applications where high ripple tolerance, extended endurance and a small footprint are required.

Key value propositions include a 1.8 mF capacitance at 35 V, low ESR/impedance, rated operation across −40°C to 105°C, and long endurance up to 10,000 hours at 105°C for sustained performance in demanding environments.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with a rated voltage of 35 V and tolerance of −20% to +20% at 120 Hz, 20°C.
• Low Impedance Performance — Measured impedance of 67 mOhm supports efficient ripple handling and low loss in power circuits.
• High Ripple Current Capability — Low‑frequency ripple current of 2.288 A (120 Hz) and high‑frequency capability of 2.86 A (10 kHz), enabling robust AC ripple handling across frequency ranges.
• Reliability & Endurance — Rated for 10,000 hours at 105°C (UHE series endurance specification for 16–100 V units), providing long operational life under elevated temperature and bias.
• Electrical Loss — Dissipation factor (tan δ) of 0.12 measured at 20°C, 120 Hz, suitable for general‑purpose power applications requiring predictable loss characteristics.
• Leakage Current — Specified leakage current of 630 µA (after rated voltage application conditions), useful for evaluating standby and bias current budgets.
• Compact Radial Package — Can size φ18 × 20L (D: 18 mm × L: 20 mm) with radial lead spacing of 7.5 mm (±0.5 mm) and lead diameters consistent with radial lead configuration for through‑hole assembly.
• Operating Temperature Range — −40°C to +105°C suitable for a wide range of ambient conditions.
• RoHS Compliant & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Power supply smoothing — Bulk capacitance and low impedance make the UHE1V182MHD3 suitable for smoothing DC power rails and reducing voltage ripple in power supplies.
• Decoupling for power rails — Use where stable voltage under dynamic load is required; the capacitor’s ripple current ratings support decoupling across low and higher frequencies.
• Energy storage for transient demands — Compact radial package provides local energy reserve for short transient events in general‑purpose electronic assemblies.

Unique Advantages

• Compact footprint with high capacitance — 1800 µF in a φ18 × 20L can saves board space while providing substantial bulk storage.
• Low impedance and measurable ESR — 67 mOhm impedance supports efficient power delivery and simplified thermal/ripple management in designs.
• Wide frequency ripple capability — Specified ripple currents at both 120 Hz and 10 kHz demonstrate utility across common power‑conversion and switching frequencies.
• Extended high‑temperature endurance — Rated 10,000 hours at 105°C for designs that require long service life under elevated temperature and bias conditions.
• Through‑hole radial format — Radial lead construction and defined lead spacing simplify board layout and replacements in repairable equipment.
• Regulatory compliance — RoHS compliant construction supports environmentally constrained designs.
