UPW1E681MPD

The UPW1E681MPD is a radial-lead, miniature aluminum electrolytic capacitor from Nichicon's UPW series designed for high-reliability power applications. It delivers 680 µF at 25 V in a compact φ10 × 20 mm can, optimized for low impedance and sustained operation in demanding thermal environments.

Typical use cases include switching power supplies and automotive electronic systems where sustained ripple handling, wide temperature range, and long endurance are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance rated at 25 V with tolerance −20% to +20%, suitable for bulk energy storage and filtering.
• Low Loss / Impedance — Tangent of loss angle (tanδ) 0.14 (measured at 20°C, 120 Hz) and specified impedance of 104 mΩ, supporting efficient ripple attenuation.
• High Ripple Current Capability — Low-frequency ripple current 915 mA (120 Hz) and high-frequency ripple current 1.22 A (10 kHz), enabling reliable performance across switching spectra.
• Leakage Current — Specified leakage current of 510 µA, measured under product data conditions, for predictable bias behavior.
• High-Temperature Endurance — Rated for 5000 hours at 105°C, providing long-term stability in elevated-temperature applications.
• Wide Operating Temperature — −55°C to +105°C operating range for use across harsh ambient conditions.
• Package & Mounting — Radial lead can, size φ10 × 20 mm with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for flexible assembly.
• AEC-Q200 Qualified — Meets AEC-Q200 reliability rating and is offered as a high-reliability product suitable for automotive electronics.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering in DC–DC converters and switch-mode power supplies where low impedance and high ripple current are needed.
• Automotive Electronics — Power rail decoupling and energy buffering in automotive control modules, leveraging AEC-Q200 qualification and 105°C endurance.
• Power Management Modules — Local energy storage and transient suppression in power management circuits that require compact, high-capacitance passives.

Unique Advantages

• Engineered for Low Impedance: The 104 mΩ impedance and tanδ 0.14 (120 Hz, 20°C) support improved ripple suppression and stable regulator behavior.
• Compact High Capacitance: 680 µF in a φ10 × 20 mm can reduces board space compared with larger form factors while retaining energy storage capacity.
• Robust Thermal Endurance: 5000 hours at 105°C helps ensure sustained performance in high-temperature operating environments.
• Wide Frequency Ripple Performance: Rated ripple currents at 120 Hz and 10 kHz (915 mA and 1.22 A) provide predictable behavior from low to high switching frequencies.
• Automotive-Grade Reliability: AEC-Q200 rating signals suitability for automotive electronics and other high-reliability systems.
• Flexible Assembly Options: Radial lead form with 5 mm lead spacing and bulk/bag packing simplifies through-hole assembly and inventory handling.
