UPW1A681MPD6

The UPW1A681MPD6 from Nichicon is a miniature, radial‑lead aluminum electrolytic capacitor designed for low impedance and high reliability in switching power supply applications. It provides 680 µF capacitance at 10 V in a compact radial can package suited to space‑constrained power filtering and decoupling tasks.

Engineered for demanding environments, this part carries an AEC‑Q200 rating and is specified for operation from −55 °C to +105 °C with a rated life of 3,000 hours at 105 °C, making it appropriate for automotive and industrial power electronics where long life and thermal endurance are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a 10 V rated voltage, with a capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Low Impedance — Specified impedance of 170 mΩ, providing improved ripple suppression and better AC performance in switching regulator outputs.
• Compact Radial Can — Small footprint (L: 1.5 × D: 0.8 cm) in a radial, can package with 3.5 mm lead spacing, enabling dense board layouts and through‑hole mounting.
• Ripple Current Capability — Rated ripple current of 547.5 mA at 120 Hz and 730 mA at 10 kHz, with frequency coefficients available across the typical range for power‑supply use.
• Wide Temperature Range — Operating temperature from −55 °C to +105 °C supports use across harsh thermal environments.
• AEC‑Q200 Qualified — AEC‑Q200 rating for enhanced reliability in automotive and other high‑reliability applications.
• Long Life at Elevated Temperature — Specified lifetime of 3,000 hours at 105 °C under rated conditions.
• Polarized, Through‑Hole Mounting — Polarized aluminum electrolytic construction with radial lead mounting for robust mechanical attachment and serviceability.
• Leakage Current Specification — Leakage current after 1 minute at 20 °C is not more than 0.03CV (µA), per Nichicon datasheet methodology.

Typical Applications

• Switching Power Supplies — Output filtering and bulk decoupling in compact DC–DC converters and PSU modules where low impedance and space savings matter.
• Automotive Electronics — Power rail smoothing and energy storage in automotive systems, leveraging the AEC‑Q200 qualification and high temperature capability.
• Industrial Power Modules — Local bulk capacitance and ripple attenuation for compact power assemblies operating across −55 °C to +105 °C.

Unique Advantages

• Space‑efficient form factor: The 1.5 × 0.8 cm can delivers 680 µF in a small footprint to save PCB area in dense power designs.
• Low impedance for cleaner rails: 170 mΩ impedance helps reduce ripple and improves AC performance on regulator outputs.
• Automotive‑grade reliability: AEC‑Q200 qualification and a 3,000‑hour life at 105 °C support long‑term operation in demanding environments.
• Broad temperature operation: −55 °C to +105 °C rating covers a wide range of deployment conditions without derating design intent.
• Through‑hole robustness: Radial lead package and can construction provide durable mechanical mounting for vibration‑prone applications.
