UHE1V182MHD

The UHE1V182MHD is a Nichicon UHE series radial-lead aluminum electrolytic capacitor offering 1.8 mF (1800 µF) nominal capacitance at a 35 V rated voltage. It combines a compact φ12.5 × 40 mm can and radial lead package with engineered low impedance and long-term endurance for demanding general-purpose electronic designs.

Designed for applications that require high ripple handling, long life at elevated temperature, and RoHS compliance, this capacitor delivers specific performance characteristics—such as low impedance (56 mΩ), high ripple current capability, and 10,000-hour endurance at 105°C—that make it suitable for a wide range of equipment requiring reliable bulk capacitance.

Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) nominal capacitance with a rated voltage of 35 V and capacitance tolerance of -20% to +20%.
• Long Endurance: Specified life of 10,000 hours at 105°C, meeting the UHE series endurance for 16–100 V parts in φD ≥ 12.5 cases.
• Low Impedance: 56 mΩ impedance (specified) for improved transient response and reduced power loss in high-current circuits.
• High Ripple Current Capacity: Rated ripple currents of 2.68 A at 120 Hz (low frequency) and 3.35 A at 10 kHz (high frequency) for effective AC ripple handling.
• Dielectric Loss: Tangent of loss angle (tanδ) of 0.12 measured at 20°C, 120 Hz, indicating controlled dissipation factor for power applications.
• Compact Radial Package: φ12.5 × 40 mm can with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies; available in bulk or bag packing.
• Leakage Current: Specified leakage current of 630 µA, enabling predictable quiescent behavior in bias circuits.
• Environmental Compliance: RoHS compliant.

Typical Applications

• General-purpose electronics: Provides bulk capacitance and ripple filtering where a 35 V, 1.8 mF polarized radial electrolytic is specified.
• Power supply smoothing: Suited to smoothing and energy-storage roles that benefit from the capacitor’s low impedance and rated ripple current values.
• Industrial and commercial equipment: Applicable in designs requiring long life at elevated temperature (10,000 h at 105°C) and reliable through-hole mounting.

Unique Advantages

• High ripple capability: Rated ripple currents of 2.68 A (120 Hz) and 3.35 A (10 kHz) reduce thermal stress under AC-loading conditions, improving operational stability.
• Long-term thermal reliability: 10,000-hour endurance at 105°C supports longer maintenance intervals and predictable lifetime performance in hot environments.
• Compact footprint for high capacitance: 1.8 mF in a φ12.5 × 40 mm can helps conserve board space while delivering significant bulk energy storage.
• Predictable electrical behavior: Low impedance (56 mΩ) and a specified tanδ (0.12 at 20°C, 120 Hz) support accurate power-design calculations and thermal management.
• Standardized mounting and packing: Radial-lead through-hole format with 5.0 mm lead spacing and bulk/bag packing options simplify assembly and inventory handling.
• Regulatory compliance: RoHS compliance addresses material-restriction requirements for many commercial and industrial projects.
