UPS1C681MPD

The UPS1C681MPD is a miniature, radial-leaded aluminum electrolytic capacitor from Nichicon’s UPS series designed for switching power supplies and general-purpose power applications. It delivers 680 µF at 16 V in a compact φ10 × 16 mm can with low impedance and defined ripple current capability.

Engineered for wide operating temperature and long endurance, this high-reliability capacitor supports designs that require bulk decoupling, smoothing and high-frequency ripple handling across –55°C to 105°C with a rated life of 2000 hours at 105°C.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20% for predictable energy storage.
• Low Impedance: Specified impedance of 140 mΩ (20°C / 100 kHz) to help reduce voltage ripple and support fast transient currents.
• Ripple Current Performance: Low-frequency ripple current 568 mA at 120 Hz and high-frequency ripple current 800 mA at 10 kHz for both bulk smoothing and higher frequency decoupling roles.
• Loss Characteristics: tan δ = 0.16 measured at 20°C, 120 Hz, offering predictable dissipation behavior in circuit designs.
• Leakage Current: Leakage current of 326.4 µA (calculated per 0.03CV after 1 minute at 20°C) for reliable bias behavior.
• Reliability & Endurance: Rated lifetime of 2000 hours at 105°C (φD = 8 to 10 mm range), supporting extended operation in high-temperature environments.
• Wide Temperature Range: Operational from −55°C to 105°C to cover demanding industrial and power-electronics environments.
• Compact Radial Package: Radial lead mounting with φ10 × 16 mm case size and 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• RoHS Compliant: Meets RoHS directive requirements as specified in the product information.

Typical Applications

• Switching Power Supplies: Input and output smoothing where low impedance and sustained ripple current capacity reduce output ripple and improve regulator stability.
• DC–DC Converters: Bulk decoupling and energy storage in compact converter modules requiring a small footprint and reliable thermal endurance.
• Power Management Modules: Local decoupling for power rails and transient buffering in industrial and consumer power systems.
• Industrial Control Electronics: Filtering and smoothing in control boards that operate across wide temperature ranges and require long endurance at elevated temperatures.

Unique Advantages

• Compact energy storage: 680 µF in a φ10 × 16 mm can minimizes board area for bulk capacitance needs without sacrificing performance metrics.
• Designed for ripple duty: Specified ripple currents at both low and high frequencies let designers optimize placement for input or output filtering roles.
• Thermal endurance: 2000-hour life at 105°C provides a measurable reliability baseline for high-temperature deployments.
• Predictable electrical behavior: Measured tan δ and leakage current values allow accurate thermal and leakage budgeting in power designs.
• Radial-lead mounting: Simple radial lead form factor and 5 mm lead spacing enable straightforward through-hole assembly and prototyping.
• Regulatory compliance: RoHS compliance supports use in regulated product lines without additional material screening.
