UPA1C681MPD6

The UPA1C681MPD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UPA series, offering 680 µF capacitance at a 16 V rating in a compact φ10 × 12.5 mm can. It is designed as a miniature, low-impedance solution for general-purpose power filtering and switching power supply applications.

Key electrical characteristics include low impedance (126 mΩ), high ripple-current capability (675 mA at 120 Hz and 900 mA at 10 kHz), a wide operating temperature range of −55°C to 105°C, and an endurance rating of 4000 hours at 105°C. The part is RoHS-compliant and available in bulk/bag packaging for production use.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance, suitable for bulk energy storage and smoothing in low-voltage power rails.
• Low Impedance: 126 mΩ impedance delivers improved transient response and reduced voltage ripple under load.
• High Ripple Current Capability: Supports 675 mA at 120 Hz and 900 mA at 10 kHz, enabling reliable operation in switching power supplies and high-frequency filtering.
• Thermal & Endurance Performance: Operates across −55°C to 105°C with an endurance rating of 4000 hours at 105°C for the φ10 case size.
• Loss Characteristic: tanδ (DF) of 0.16 measured at 20°C, 120 Hz, delivering predictable dissipation behavior in design calculations.
• Compact Radial Package: φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole PCB layouts.
• Leakage Current: Specified leakage current of 326.4 µA, useful when budgeting quiescent currents in power-sensitive designs.
• Regulatory: RoHS compliant and in mass-production status for stable supply.

Typical Applications

• Switching Power Supplies: Bulk smoothing and ripple handling where high-frequency ripple currents (up to 900 mA at 10 kHz) and low impedance improve regulator stability.
• Power Rail Decoupling in Compact Modules: Space-constrained power modules benefit from the φ10×12.5 mm footprint and radial lead mounting for through-hole assemblies.
• General-Purpose Electronic Equipment: Energy storage and filtering across a wide temperature range (−55°C to 105°C) for consumer and industrial applications.

Unique Advantages

• High ripple-current tolerance: Allows designers to handle both low-frequency and high-frequency ripple, reducing the need for additional parallel components.
• Low impedance footprint: 126 mΩ impedance improves transient response and reduces voltage ripple without increasing board area.
• Compact radial can: Small φ10 × 12.5 mm case with 5 mm lead spacing simplifies placement in dense through-hole layouts.
• Wide temperature and long-life rating: −55°C to 105°C operation and 4000 hours endurance at 105°C for the φ10 case support reliable performance in demanding thermal environments.
• Predictable dissipation and leakage specs: tanδ = 0.16 (20°C, 120 Hz) and 326.4 µA leakage current enable accurate thermal and standby-current planning.
• Production-ready supply: RoHS compliance and mass-production status help ensure availability for ongoing manufacturing needs.

Why Choose UPA1C681MPD6?

UPA1C681MPD6 combines compact packaging with low impedance and robust ripple-current capability, making it a practical choice for engineers designing power filtering and energy-storage functions in switching supplies and general-purpose electronics. The Nichicon UPA series specification of −55°C to 105°C operation and 4000-hour endurance at 105°C (φ10 case) provides a reliable performance envelope for demanding thermal and runtime requirements.

This part is suited for designs that require measurable, verifiable electrical characteristics—such as impedance, tanδ, leakage current, and ripple-current ratings—so teams can size and qualify power systems with confidence while maintaining a small PCB footprint and standard radial-lead assembly.
