UPJ1A681MPD6

The UPJ1A681MPD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized can-style capacitor specified at 680 µF and 10 V, designed for general-purpose power applications.

Engineered for low impedance and long life, this part delivers defined electrical performance — including measured tanδ and ripple current ratings — across a wide temperature range for reliable power filtering in low-voltage circuits and switching power supplies.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with tolerance -20% to +20% at a rated voltage of 10 V, suitable for bulk filtering at low DC voltages.
• Low Loss Characteristics — Specified tanδ of 0.19 measured at 20°C and 120 Hz, providing predictable AC loss behavior for filter and decoupling designs.
• Ripple Current Handling — Low-frequency ripple current 431.8 mA (120 Hz) and high-frequency ripple current 635 mA (200 kHz) to support switching and rectifier applications.
• Leakage Current — Leakage current specified at 204 µA, enabling reliable performance in bias-sensitive circuits.
• High Endurance — Rated for 5000 hours of load life at 105°C, with an operating temperature range of -55°C to +105°C for applications requiring sustained elevated-temperature operation.
• Compact Radial Package — Can-style body φ10 × 16 mm with 5.0 mm lead spacing (±0.5 mm); available in bulk or bag packing for through-hole assembly.
• Compliance — RoHS compliant as part of Nichicon’s UPJ series.

Typical Applications

• Switching Power Supplies — Low impedance and specified ripple current make this capacitor suited for output filtering and smoothing in switching regulator designs.
• General-Purpose Power Filtering — Bulk energy storage and decoupling in low-voltage DC power rails where 10 V rating and 680 µF capacitance are required.
• Low-Voltage DC Circuits — Decoupling and smoothing on 10 V and lower DC rails where predictable leakage and loss characteristics are important.

Unique Advantages

• Measured AC Loss Specification: The tanδ value (0.19 at 20°C, 120 Hz) gives designers a clear loss metric for thermal and stability calculations.
• Dual-Frequency Ripple Ratings: Specified ripple current at both 120 Hz and 200 kHz supports designs that encounter a range of ripple frequencies, including switching environments.
• Long Elevated-Temperature Life: 5000 hours at 105°C offers extended service life for sustained thermal stress conditions.
• Compact Radial Form Factor: φ10 × 16 mm can and 5.0 mm lead spacing provide a small footprint for space-constrained through-hole assemblies.
• Predictable Leakage: A defined leakage current value (204 µA) simplifies bias budgeting for sensitive circuits.
• RoHS Compliance: Meets environmental regulatory requirements for modern electronics manufacturing.
