UHW1V392MHD

The UHW1V392MHD is a radial lead aluminum electrolytic capacitor in Nichicon's UHW series, offering 3900 µF capacitance at a 35 V rating. It combines high ripple-current handling with a compact φ16 × 35.5 mm can and radial lead mounting for general-purpose electronic power applications.

Designed for engineers who need bulk capacitance with low impedance and long-term stability, this part delivers high-frequency performance and a 10000-hour endurance at 105°C for reliable operation in power supply and energy-storage roles.

Key Features

• High Capacitance / Rated Voltage — 3.9 mF (3900 µF) nominal capacitance at 35 V with a capacitance tolerance of −20% to +20% for predictable bulk energy storage.
• High Ripple Current — Supports 3.15 A low-frequency ripple (120 Hz) and 4.2 A high-frequency ripple (10 kHz), enabling better performance in switching power supplies and converter outputs.
• Low Impedance — Specified impedance of 30 mOhm to minimize voltage ripple and improve transient response on power rails.
• Long Endurance — Rated for 10000 hours at 105°C, providing sustained performance in elevated-temperature environments.
• Compact Radial Package — φ16 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) suits through-hole PCB layouts where space and serviceability matter.
• Wide Operating Temperature — Operates from −40°C to 105°C, covering a broad range of environmental conditions.
• Electrical Loss & Leakage — Tangent of loss angle (tanδ) 0.15 at 20°C/120 Hz and a leakage current specification of 1365 µA for this part number.
• Manufacturing & Compliance — RoHS‑compliant and available in bulk or bag packing; currently in mass production.

Typical Applications

• Power supply filtering — Bulk capacitance and low impedance reduce output ripple and improve regulator stability in DC power rails.
• DC–DC converter output smoothing — High ripple-current capability at both 120 Hz and 10 kHz supports switching converter outputs and intermediate bus smoothing.
• Energy storage and hold-up — Large 3900 µF capacitance provides short-term energy buffering for transient loads and hold-up intervals.

Unique Advantages

• High ripple tolerance: Handles up to 4.2 A at high frequency, enabling smaller capacitor arrays or reduced parallel components in converter designs.
• Compact footprint with high capacity: 3.9 mF in a φ16 × 35.5 mm can frees board space while delivering substantial bulk capacitance.
• Low impedance for improved performance: 30 mOhm impedance helps reduce voltage drop under load and improves transient response.
• Long life at elevated temperature: 10000-hour rating at 105°C supports designs that require extended field life in warm environments.
• Designed for practical assembly: Radial lead format with defined lead spacing simplifies through-hole placement and manual or automated insertion.
