UHW1V391MPD6

The UHW1V391MPD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. It is a radial-lead, polarized capacitor specified at 390 µF and 35 V, designed for general-purpose electronic applications that require compact size and sustained performance.

Key engineering attributes include low impedance (120 mΩ), high ripple-current capability across frequency, a wide operating temperature range (−40 °C to 105 °C) and a rated endurance of 10,000 hours at 105 °C, making it suitable where long-term stability and thermal resilience are required.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a rated voltage of 35 V and a capacitance tolerance of −20% to +20%.
• Low Impedance — 120 mΩ impedance supports effective AC performance and helps reduce voltage drop under ripple conditions.
• High Ripple-Current Capability — Rated ripple currents of 980 mA at 120 Hz and 1.96 A at 10 kHz provide robust handling of both low- and high-frequency ripple.
• Loss Characteristics — tanδ (DF) of 0.11 measured at 20 °C, 120 Hz for stable loss behavior in typical operating conditions.
• Long Endurance — 10,000 hours life rating at 105 °C for sustained reliability in elevated-temperature environments.
• Wide Temperature Range — Operating temperature range from −40 °C to 105 °C to cover a broad set of ambient conditions.
• Compact Radial-Lead Package — φ8 × 20 mm can with 3.5 mm lead spacing (±0.5 mm) in a radial lead form; available in bulk or bag packing.
• Leakage Current — Specified leakage current of 136.5 µA after standard application conditions.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-Purpose Electronics — Designed for use across general-purpose electronic designs where a compact, polarized aluminum electrolytic capacitor is required.
• Power Modules and Supplies — Low impedance and high ripple-current ratings support power-supply filtering and stabilization in compact assemblies.
• High-Temperature Environments — The −40 °C to 105 °C operating range and 10,000-hour endurance at 105 °C make this part suitable for designs exposed to elevated ambient temperatures.

Unique Advantages

• High Ripple Handling: With 1.96 A ripple current at 10 kHz and 980 mA at 120 Hz, the capacitor sustains significant AC stress without compromising performance.
• Compact Footprint: φ8 × 20 mm radial-can construction and 3.5 mm lead spacing provide a small, easy-to-place component for space-constrained PCBs.
• Long-Term Thermal Reliability: 10,000-hour endurance rating at 105 °C supports product longevity in thermally demanding applications.
• Predictable Loss and Leakage: Specified tanδ (0.11 at 20 °C, 120 Hz) and a defined leakage current (136.5 µA) allow accurate thermal and leakage budgeting in designs.
• RoHS Compliance: Meets RoHS requirements for use in regulated regions and assemblies.
• Mass Production Availability: Product is in mass production, facilitating volume supply planning.
