UPA1C681MPD

The UPA1C681MPD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power filtering and switching power supply applications. It combines compact dimensions with measurable low impedance and high ripple-current capability to support dense power rail and decoupling designs.

Packaged in a φ8 × 15 mm can with 3.5 mm lead spacing, this polarized capacitor is optimized for board-level radial lead mounting and is offered in bulk or bag packing for production use. It is RoHS compliant and available in mass production.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 16 V and a capacitance tolerance of ±20% (120 Hz, 20°C).
• Low Impedance — Measured impedance of 124 mΩ supports effective smoothing and decoupling in power circuits.
• High Ripple Current Capability — Low-frequency ripple current of 645 mA at 120 Hz and high-frequency ripple current of 860 mA at 10 kHz to handle dynamic power loads.
• Loss Tangent (tan δ) — tan δ of 0.16 measured at 20°C, 120 Hz, providing a quantified dielectric loss characteristic for design margin calculations.
• Reliability & Endurance — Rated lifetime of 3000 hours at 105°C under rated voltage and specified ripple conditions; leakage current specified at 326.4 µA for this part.
• Operating Range — Wide operating temperature range from −55°C to +105°C for use across varied thermal environments.
• Radial Lead Package — φ8 can with 3.5 mm lead spacing (lead spacing tolerance ±0.5 mm) for straightforward axial/radial through-hole assembly.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit manufacturing workflows.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where compact, high‑ripple capability is required.
• DC–DC Converters — Input/output decoupling on low-voltage rails to stabilize transient loads and reduce voltage ripple.
• Industrial Power Modules — Local energy storage and filtering in compact power assemblies operating across −55°C to +105°C.
• General Purpose Power Filtering — Board-level decoupling and noise suppression for consumer and commercial electronics.

Unique Advantages
