UPS1E681MPD

The UPS1E681MPD is a miniature, low‑impedance aluminum electrolytic capacitor from Nichicon’s UPS series. It is a radial‑lead, polarized capacitor designed for general purpose power applications, with performance targeted at switching power supplies and power‑rail smoothing.

Key attributes include 680 µF capacitance at a 25 V rating, a wide operating temperature range from −55°C to +105°C, RoHS compliance, and specific ripple current and impedance characteristics that support demanding power environments.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance rated for 25 V, suitable for bulk and smoothing applications in low‑voltage power rails.
• Low Impedance — Specified impedance of 110 mΩ, enabling effective filtering and reduced voltage ripple in switching regulator outputs.
• Ripple Current Handling — Rated ripple current of 710 mA at 120 Hz and 1.0 A at 10 kHz to support both low‑ and high‑frequency ripple conditions.
• Wide Temperature Range — Operating range from −55°C to +105°C for sustained performance across harsh thermal environments.
• High‑Temperature Lifetime — Rated lifetime of 2000 hours at 105°C, supporting longevity under elevated operating temperatures.
• Radial Lead Package — Compact radial, can‑style package with 5 mm lead spacing and physical dimensions L: 2 × D: 1 cm for space‑constrained designs.
• Polarized, General‑Purpose Use — Polarized aluminum electrolytic construction for conventional DC filtering and energy storage tasks.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where low impedance and high ripple current capability reduce output ripple and improve regulator stability.
• DC Power Rails — Decoupling and energy storage on low‑voltage rails in consumer and industrial electronics, leveraging the 680 µF / 25 V rating.
• Compact Power Modules — Space‑efficient radial can package and small footprint suit power modules and compact PCB layouts.
• Industrial Power Equipment — Wide −55°C to +105°C operating range and 2000 h life at 105°C for demanding thermal environments and continuous operation.

Unique Advantages

• Engineered for Low Ripple Losses — Low impedance (110 mΩ) combined with high ripple current ratings reduces heating and improves filtering effectiveness.
• Broad Temperature Capability — Operation from −55°C to +105°C allows deployment across a wide range of environments without derating design expectations.
• Compact, Easy-to‑Mount Package — Radial lead format with 5 mm lead spacing simplifies through‑hole assembly and prototyping in compact designs.
• Durability at Elevated Temperatures — 2000‑hour rating at 105°C supports long‑term performance in continuously heated enclosures.
• Regulatory Compliance — RoHS conformity supports use in products that require restricted‑substance compliance.
