UHW1V681MPD

The UHW1V681MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic equipment. It combines a compact φ10×25L package and radial mounting with characteristics targeted at power filtering and bulk decoupling where elevated ripple handling and low impedance are important.

Key value propositions include high ripple-current capability at both low and high frequencies, low impedance, and long endurance at elevated temperature, making it suited to designs that require robust, long-life capacitance in a small footprint.

Key Features

• Capacitance & Rated Voltage — 680 µF nominal capacitance with tolerance −20% to +20% at a rated voltage of 35 V.
• Low Impedance — Rated impedance of 51 mΩ, supporting effective high-frequency performance and reduced voltage ripple under load.
• High Ripple Current — Low-frequency ripple current of 1.74 A (120 Hz) and high-frequency ripple current of 2.9 A (10 kHz) for demanding power applications.
• Dissipation Factor (tan δ) — tanδ of 0.11 measured at 20°C, 120 Hz for the 35 V rating.
• Leakage Current — Specified leakage current of 238 µA.
• Temperature Range & Endurance — Operating temperature −40°C to +105°C with an endurance rating of 10,000 hours at 105°C.
• Package & Mounting — Radial-lead can, size φ10 × 25L, lead spacing 5.0 mm (±0.5 mm), supplied in bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power supplies — Bulk energy storage and smoothing where sustained ripple current and low impedance reduce output voltage ripple.
• DC–DC converters and regulators — Decoupling at input or output stages to support transient loads and improve stability.
• Industrial and consumer electronics — General-purpose filtering in compact assemblies requiring long life at elevated temperature.

Unique Advantages

• Compact, high-capacitance package — 680 µF in a φ10×25L radial can saves PCB area while providing substantial bulk capacitance.
• High ripple handling across frequencies — Specified ripple currents at 120 Hz and 10 kHz (1.74 A and 2.9 A) give designers quantified assurance for both low- and high-frequency ripple environments.
• Low impedance for better regulation — 51 mΩ impedance helps reduce voltage drop and improves filtering performance under dynamic load.
• Designed for long operational life — 10,000 hours at 105°C supports reliability in elevated-temperature applications.
• Radial-lead form for through-hole assemblies — Simplifies replacement, prototyping, and mechanical robustness in vertical-mount layouts.
• RoHS compliant — Meets environmental requirements for lead-free designs.
