UPJ1A680MDD

UPJ1A680MDD is a miniature, polarized aluminum electrolytic capacitor from Nichicon’s UPJ series, designed for low-impedance, high-reliability power applications. It delivers 68 µF at 10 V in a compact radial can (φ5 × 11 mm) with 2.0 mm lead spacing, targeting general-purpose power filtering and switching-supply output decoupling.

Key electrical characteristics — including tanδ 0.19 (20°C, 120 Hz), defined ripple-current values at low and high frequencies, and a rated operating range of −55°C to +105°C — provide predictable performance for engineers specifying low-voltage power rails in space-constrained assemblies.

Key Features

• Capacitance & Voltage 68 µF nominal capacitance at a 10 V rating with ±20% tolerance, suitable for low-voltage decoupling and bulk filtering.
• Low Loss (tan δ) tanδ = 0.19 measured at 20°C, 120 Hz, supporting efficient filtering with controlled dissipation.
• Ripple Current Performance Low-frequency ripple current 49.47 mA (120 Hz) and high-frequency ripple current 97 mA (200 kHz) for switching-supply ripple handling.
• Leakage Current Specified leakage current of 20.4 µA for predictable bias behavior after voltage application.
• Temperature & Endurance Rated operating range −55°C to +105°C with an endurance/life rating of 2000 hours at 105°C under rated conditions.
• Compact Radial Package Small φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm) and radial-lead mounting; available in bulk or bag packing.
• RoHS Compliant Conforms to RoHS requirements as specified in the product data.

Typical Applications

• Switching Power Supplies The UPJ series is specified for low impedance and is well suited to smoothing and output decoupling in switching converters at low voltages.
• General-Purpose Power Filtering Polarized radial format and defined leakage/ripple specifications make it appropriate for decoupling and bulk filtering in consumer and industrial electronics.
• Space-Constrained Through-Hole Designs Compact φ5×11 mm package with tight lead spacing fits densely populated PCBs where a reliable radial electrolytic is required.

Unique Advantages

• Low-Impedance Series Design UPJ series emphasis on low impedance helps reduce voltage ripple on converter outputs and power rails.
• Quantified Endurance 2000-hour rating at 105°C gives a measurable reliability baseline for thermal-stress and lifetime planning.
• Clear, Measured Specs Specified tanδ, leakage current, and ripple-current values enable accurate simulation and thermal budgeting during design.
• Space-Efficient Form Factor Small radial can and 2.0 mm lead spacing streamline integration into compact through-hole assemblies.
• Regulatory Compliance RoHS conformity simplifies environmental compliance for final products.
