UPJ1K680MHD6

The UPJ1K680MHD6 from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPJ series, engineered for low impedance and high reliability. It delivers 68 µF nominal capacitance at a rated voltage of 80 V in a compact φ12.5 × 15 mm can with 5 mm lead spacing, making it suitable for power-filtering roles in switching power supplies and general-purpose power electronics.

Key Features

• Capacitance & Rated Voltage — 68 µF nominal capacitance with an 80 V rated voltage and capacitance tolerance of ±20% (–20%~20%).
• Low Impedance Design — Part of the UPJ series characterized for low impedance, helping reduce ripple and improve transient response in power circuits.
• Endurance — Specified load life of 5000 hours at +105°C, supporting sustained operation under elevated temperature and bias conditions.
• Ripple Current Handling — Low-frequency ripple current of 126.99 mA at 120 Hz and high-frequency ripple current of 249 mA (specified condition), enabling effective smoothing in both line-frequency and switching-frequency environments.
• Loss Angle & Leakage — Tangent of loss angle (tan δ) of 0.08 measured at 20°C, 120 Hz, 80 V, and a measured leakage current of 163.2 µA for predictable dissipation and standby behavior.
• Mechanical & Mounting — Radial lead, polarized can (φ12.5 × 15 mm), lead spacing 5 mm with ±0.5 mm tolerance; packaging available as Bulk (no terminal forming) / Bag Packing.
• Temperature Range & Reliability — Operates from –55°C to +105°C and is RoHS compliant.

Typical Applications

• Switching Power Supplies — Input/output smoothing and energy buffering where low impedance and specified ripple current improve converter stability and efficiency.
• DC/DC Converters — Bulk and decoupling capacitance for regulated rails in compact power modules, leveraging the high-voltage (80 V) rating.
• General-Purpose Power Filtering — Smoothing and noise reduction in industrial and consumer power electronics across a wide temperature range (–55°C to +105°C).
• Industrial Control Electronics — Long-life endurance and robust temperature tolerance suit applications requiring sustained performance under thermal stress.

Unique Advantages

• Designed for low-impedance performance — Series-level low-impedance characteristics help minimize voltage ripple and improve transient response in switching environments.
• High-temperature endurance — 5000-hour rated life at +105°C supports reliability in sustained high-temperature operation.
• Clear ripple specifications — Separate low-frequency (126.99 mA at 120 Hz) and high-frequency (249 mA) ripple current ratings allow confident selection for both mains-frequency and switching-frequency circuits.
• Compact power-dense form factor — φ12.5 × 15 mm radial can with 5 mm lead spacing delivers significant capacitance and voltage rating in a small footprint for dense PCB layouts.
• Predictable electrical behavior — Specified tan δ of 0.08 (20°C, 120 Hz, 80 V) and defined leakage current provide measurable parameters for thermal and standby loss budgeting.
• RoHS compliant — Meets RoHS requirements for restricted substances.
