UHV1C681MPD

The UHV1C681MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHV series, offering 680 µF capacitance in a compact φ10 × 12.5 mm can. Designed for general-purpose low-voltage circuits, it combines low impedance, high ripple capability and long-term endurance for board-level power applications.

Key value comes from measurable electrical performance: a rated voltage of 16 V, low-frequency and high-frequency ripple current ratings, and an endurance rating of 6000 hours at 105°C—making it suitable where compact bulk capacitance and reliable ripple handling are required.

Key Features

• Capacitance & Tolerance — 680 µF with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 16 V DC voltage rating suitable for low-voltage power rails.
• Low Impedance — Specified impedance of 133 mΩ supports reduced voltage ripple under load.
• High-Frequency Performance — UHV series design offers lower impedance at high frequency; tanδ (DF) = 0.15 at 20°C, 120 Hz for this voltage class.
• Ripple Current & Reliability — Low-frequency ripple current 816 mA (120 Hz) and high-frequency ripple current 1.36 A (100 kHz); endurance 6000 hours at 105°C under rated ripple and DC bias.
• Leakage Current — Typical leakage current up to 108.8 µA (after 2 minutes at 20°C), consistent with the part’s capacitance and rated voltage.
• Package & Mounting — Radial lead, φ10 × 12.5 mm can with 5.0 mm lead spacing (±0.5 mm); available in Bulk (No Terminal Forming) or Bag packing.
• Environmental & Production Status — RoHS compliant and available in mass production.

Typical Applications

• General-purpose power filtering — Compact 680 µF capacitance at 16 V for smoothing and energy storage on low-voltage rails.
• Board-level bulk decoupling — Small φ10 × 12.5 mm can and radial leads for easy placement where bulk capacitance and space savings are needed.
• Switching regulator ripple management — Lower high-frequency impedance and a 1.36 A ripple rating at 100 kHz help reduce output ripple in switching power supplies.
• Industrial and embedded electronics — Wide operating range (−40°C to +105°C) and 6000 h endurance at 105°C support sustained operation in temperature-stressed systems.

Unique Advantages

• Measured low impedance: 133 mΩ impedance supports efficient smoothing and reduced ripple voltage on power rails.
• High ripple capability: Rated for 816 mA at 120 Hz and 1.36 A at 100 kHz, enabling robust performance with both low- and high-frequency ripple sources.
• Compact radial can: φ10 × 12.5 mm size with 5.0 mm lead spacing delivers significant capacitance in a small footprint for dense board designs.
• Long endurance at elevated temperature: 6000 hours at 105°C under rated ripple current provides predictable long-term behavior in demanding applications.
• Polarized, board-friendly mounting: Radial-lead construction simplifies through-hole assembly and handling for prototyping and production.
• RoHS compliant & production-ready: Environmentally compliant and listed as mass production for dependable supply.
