UHV1V182MHD

The UHV1V182MHD is a radial-lead aluminum electrolytic capacitor offering 1800 µF capacitance at a 35 V rating in a compact φ12.5 × 35.5 mm can. It is engineered as part of Nichicon’s UHV series to provide low impedance at high frequency and high ripple-current capability for general-purpose electronic designs.

Designed for continuous operation across a wide temperature range (−40°C to +105°C) with an endurance rating of 6000 hours at 105°C, this polarized radial component is suitable where bulk capacitance, ripple handling and long-term thermal endurance are required.

Key Features

• Capacitance & Voltage — 1800 µF nominal capacitance with a rated voltage of 35 V and a tolerance of −20% to +20%.
• Low impedance — Impedance specified at 29 mΩ, supporting lower AC voltage drop at the device terminals.
• High-frequency loss (tan δ) — tanδ = 0.11 (measured at 20°C, 120 Hz) for predictable loss behavior in AC applications.
• High ripple current capability — Low-frequency ripple current 2.355 A at 120 Hz and high-frequency ripple current 3.925 A at 100 kHz, enabling effective ripple handling across a broad frequency range.
• Leakage current — Specified leakage current of 630 µA (measured after 2 minutes at 20°C under rated voltage conditions).
• Thermal endurance — Rated life of 6000 hours at 105°C under DC bias plus rated ripple current.
• Package and mounting — Radial lead mounting in a φ12.5 mm can (φ12.5 × 35.5 mm) with 5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Environmental compliance — RoHS compliant per product data.

Typical Applications

• General-purpose power circuitry — Bulk capacitance and ripple handling for general-purpose power supplies and power converter designs.
• Decoupling and filtering — Low-impedance, high-capacitance option for smoothing and decoupling in electronic subsystems operating up to 35 V.
• High-frequency support — Supports high-frequency ripple currents (specified at 100 kHz) for applications requiring stable AC performance.

Unique Advantages

• High ripple handling: Specified ripple currents of 2.355 A (120 Hz) and 3.925 A (100 kHz) reduce the need for parallel devices in many designs.
• Compact, high-capacity package: 1800 µF in a φ12.5 × 35.5 mm can provides substantial bulk capacitance in a small radial-lead footprint.
• Low impedance at high frequency: 29 mΩ impedance and UHV-series design characteristics deliver improved AC performance where frequency-dependent impedance matters.
• Long thermal life: 6000 hours endurance at 105°C supports reliable operation in elevated-temperature environments under rated conditions.
• Clear, manufacturable form factor: Standard radial leads with 5 mm spacing and available bulk/bag packing simplify board-level assembly and procurement.
