The UPS1A681MPD is a miniature, low‑impedance aluminum electrolytic capacitor designed for power applications. It is a radial‑lead, polarized can intended for switching power supplies and general‑purpose power filtering.

Key attributes include a 680 µF capacitance at 10 V, RoHS compliance, wide operating temperature range from −55 °C to 105 °C, and a rated endurance of 2000 hours at 105 °C—providing compact energy storage and stable performance across temperature extremes.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 10 V rated voltage and a tolerance of ±20% (120 Hz, 20 °C).
• Low Impedance — Specified impedance of 190 mΩ supports low‑loss filtering and decoupling in power rails.
• Ripple Current Handling — Rated ripple current of 426 mA at 120 Hz and 600 mA at 10 kHz for reliable operation in switching environments.
• Wide Temperature Range & Endurance — Operating range −55 °C to 105 °C with a specified lifetime of 2000 hours at 105 °C.
• Compact Radial Package — Radial can package with 5 mm lead spacing and dimensions L: 1.25 × D: 1.00 cm for space‑constrained designs.
• Polarized, General‑Purpose — Polarized aluminum electrolytic construction for general‑purpose power applications.
• Regulatory Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current capability make this capacitor suitable for bulk and output filtering in DC‑DC converters and switching regulators.
• Compact Power Modules — Small L×D footprint and radial lead mounting enable use in space‑limited power assemblies and densely populated boards.
• General‑Purpose Power Filtering — Polarized electrolytic capacitor for decoupling and smoothing in consumer and industrial electronic equipment.

Unique Advantages

• Space‑efficient energy storage — The 1.25 × 1.00 cm package offers significant capacitance in a compact radial can for dense layouts.
• Designed for switching environments — Measured ripple ratings at both 120 Hz (426 mA) and 10 kHz (600 mA) support performance across common switching frequencies.
• Low impedance for stable rail performance — 190 mΩ impedance helps reduce voltage ripple and improve transient response on power rails.
• Wide temperature capability — −55 °C to 105 °C operating range ensures functionality across demanding thermal conditions.
• Proven thermal endurance — Rated for 2000 hours at 105 °C to support durability in elevated‑temperature applications.
• RoHS‑compliant manufacturing — Meets current RoHS requirements for use in regulated markets.
