UHW1V681MPD6

The UHW1V681MPD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series. It is a radial-lead, polarized device specified at 680 µF and 35 V with low impedance and elevated ripple current capability for demanding general-purpose electronics.

Designed for applications that require compact size, extended endurance and robust ripple handling, this part delivers measurable performance in power smoothing and decoupling roles while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 35 V and a capacitance tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 1.5 A (120 Hz) and high-frequency ripple current of 2.5 A (10 kHz), enabling effective handling of AC ripple across a range of frequencies.
• Low Impedance — Specified impedance of 60 mΩ, optimized for improved performance at higher frequencies as noted in the UHW series guidance on lower impedance at high frequency range.
• Long Endurance — Rated for 10,000 hours at 105 °C, providing extended service life under rated conditions as defined by the series endurance specifications.
• Electrical Losses & Leakage — Tangent of loss angle (tan δ) of 0.11 at 20 °C, 120 Hz, and a measured leakage current of 238 µA, supporting predictable dissipation and standby behavior.
• Compact Radial Can — Cylindrical case φ10 × 20 mm (φ10×20L) with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assembly.
• Wide Temperature Range & Compliance — Operating from −40 °C to +105 °C and RoHS compliant, suitable for long-term use within the specified temperature envelope.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to match production and prototyping workflows.

Typical Applications

• Power supply smoothing — Low impedance (60 mΩ) and high ripple current (1.5 A @120 Hz, 2.5 A @10 kHz) make this capacitor suitable for smoothing output ripple on DC power rails.
• Decoupling and bulk storage — 680 µF capacitance with long endurance (10,000 h at 105 °C) provides bulk energy storage and decoupling for general-purpose electronics.
• High-frequency filtering — Series guidance on lower impedance at high frequency and specified high-frequency ripple rating support use in filters operating into the kHz range.

Unique Advantages

• High ripple tolerance in a small footprint: 1.5 A (120 Hz) and 2.5 A (10 kHz) ripple ratings combined with a φ10×20 mm case size enable compact designs without sacrificing ripple performance.
• Predictable long-term behavior: Endurance specified at 10,000 hours at 105 °C gives designers a clear reliability target for lifetime planning.
• Low ESR/impedance: 60 mΩ impedance and a tan δ of 0.11 (20 °C, 120 Hz) reduce heating and improve filtering efficiency in power circuits.
• Through-hole mounting simplicity: Radial lead package and defined 5 mm lead spacing simplify PCB layout and assembly in through-hole designs.
• Regulatory compliance: RoHS compliant construction supports restricted-substance requirements for modern product lines.
• Flexible supply formats: Bulk and bag packing options facilitate both prototypes and production runs.
