UPA1E681MPD

The UPA1E681MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPA series, engineered for compact, low-impedance power filtering. It delivers 680 µF at 25 V with high ripple-current capability and wide operating temperature range, making it suitable for switching power supplies and other general-purpose power applications.

Designed for reliability in demanding thermal environments, this part offers long endurance at elevated temperatures and is packaged for flexible assembly in bulk or bag formats.

Key Features

• Capacitance & Voltage: 680 µF rated at 25 V for bulk energy storage and decoupling in moderate-voltage power rails.
• Low Impedance: Specified impedance of 98 mΩ to reduce voltage ripple and improve transient response in power circuits.
• High Ripple Current: Handles 930 mA at 120 Hz (low frequency) and 1.24 A at 10 kHz (high frequency) to support switching regulator ripple and high-frequency decoupling.
• Thermal Endurance: Rated operating temperature range from −55 °C to +105 °C with a 4000-hour endurance at 105 °C for the φ10 case size.
• Electrical Loss (tan δ): tanδ of 0.14 measured at 20 °C, 120 Hz, indicating controlled dissipation for stable operation.
• Leakage Current & Tolerance: Leakage current specified at 510 µA and capacitance tolerance of −20% to +20% (±20%).
• Package & Termination: Radial lead, polarized aluminum can in a compact φ10 × 16L case with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• RoHS Compliant: Meets RoHS directive requirements as indicated for the UPA series.

Typical Applications

• Switching Power Supplies — Bulk smoothing and ripple attenuation where compact, low-impedance capacitors are required for reliable regulator performance.
• Power Rail Decoupling — Energy storage and transient support on DC rails that need high ripple-current handling and low ESR.
• General-Purpose Power Electronics — Suitable for a wide range of circuits requiring a 680 µF, 25 V polarized electrolytic with robust thermal endurance.

Unique Advantages

• Compact, High-Performance Footprint: φ10 × 16L size provides substantial capacitance in a small radial-lead package for space-constrained designs.
• High Ripple Tolerance: Rated ripple currents at both low and high frequencies support applications with significant AC stress from switching regulators.
• Low ESR/Impedance: 98 mΩ impedance helps minimize dissipation and voltage ripple, improving overall power efficiency and thermal performance.
• Extended Thermal Life: 4000 hours at 105 °C (φ10 case) supports long-term reliability in elevated-temperature environments.
• Flexible Assembly Options: Available in bulk or bag packing to suit through-hole assembly workflows and handling preferences.
• Regulatory Compliance: RoHS compliance reduces regulatory risk for product deployment in many markets.
