UPJ1K680MPD

The UPJ1K680MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series, offering 68 µF capacitance at an 80 V rating in a compact φ10 × 20 mm can. It is designed for general-purpose use and is specifically noted for suitability in switching power supply applications.

With a wide operating temperature range and an endurance rating for extended high-temperature operation, this polarized capacitor is intended for through-hole power filtering and decoupling roles in electronic designs.

Key Features

• Capacitance and Voltage: 68 µF capacitance with an 80 V rated voltage, suitable for mid-voltage power rail applications.
• Low Loss (tan δ): Dissipation factor (tan δ) 0.08 measured at 20°C, 120 Hz and rated voltage (80 V), indicating controlled dielectric losses under specified conditions.
• Ripple Current Performance: Specified ripple handling of 134.64 mA at 120 Hz (low frequency) and 264 mA at 200 kHz (high frequency), useful for AC ripple smoothing and switching applications.
• Leakage Current: Leakage current specified at 163.2 µA, measured under rated conditions.
• High-Temperature Endurance: Rated life of 5000 hours at +105°C (for the φ10 case), demonstrating extended reliability under elevated temperature load.
• Mechanical / Mounting: Radial lead construction with φ10×20 mm can size, 5 mm lead spacing (±0.5 mm), and bulk or bag packing for through-hole assembly.
• Environmental Compliance: RoHS compliant.

Typical Applications

• Switching Power Supplies: Low-impedance UPJ series construction and specified ripple current ratings make the UPJ1K680MPD suitable for output and bulk filtering in switching regulator circuits.
• General-Purpose Power Filtering: 68 µF at 80 V and defined leakage/tan δ characteristics support routine decoupling, smoothing, and energy-storage tasks in general electronic designs.
• Through-Hole Power Modules: Radial-lead, φ10×20 mm package with 5 mm lead spacing for use in through-hole assemblies where a compact can-style capacitor is required.

Unique Advantages

• 80 V Rated Voltage: Allows the capacitor to be used on mid-voltage rails without exceeding the rated voltage.
• Long High-Temperature Life: 5000-hour endurance at +105°C for the φ10 case size provides predictable performance under sustained thermal stress.
• Measured Ripple Capability: Explicit low- and high-frequency ripple current specifications (134.64 mA @120 Hz, 264 mA @200 kHz) enable designers to match the part to switching and AC ripple conditions.
• Controlled Dielectric Loss: tan δ of 0.08 at specified conditions helps maintain efficiency and thermal stability in power applications.
• Compact Radial Package: φ10 × 20 mm can and 5 mm lead spacing offers a small footprint for through-hole placement while keeping standard lead configuration for assembly.
• RoHS Compliance: Conforms to applicable RoHS directive requirements for regulated substances.

Why Choose UPJ1K680MPD?

The UPJ1K680MPD combines a mid-range capacitance (68 µF) with an 80 V rating and regulated electrical characteristics—tan δ, leakage current, and specified ripple currents—making it a practical choice for designers needing predictable filtering and energy storage in switching power supplies and general-purpose circuits. Its radial-lead φ10×20 mm package and 5 mm lead spacing simplify through-hole integration while the 5000-hour life at +105°C provides a clear reliability metric for thermal-intensive applications.

This part is well suited to OEMs and engineers specifying components for robust, long-lived power subsystems where measured ripple performance, controlled loss, and RoHS compliance are required.
