UPJ1K151MPD

The UPJ1K151MPD is a Nichicon UPJ series aluminum electrolytic capacitor in a miniature radial-leaded can, specified at 150 µF and 80 V. It is a high-reliability, low-impedance part designed for power applications where stable capacitance, endurance and compact packaging matter.

Typical use cases include switching power supplies and general-purpose power filtering in electronic equipment; the UPJ1K151MPD delivers long operating life and measurable ripple-handling capability for sustained operation up to 105°C.

Key Features

• Capacitance and Voltage: 150 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable for mid‑voltage power rails.
• Low-loss / Low-impedance: Specified tan δ of 0.08 measured at 20°C and 120 Hz (at rated voltage), indicating reduced reactive loss for power applications.
• Ripple current capability: Rated ripple currents of 247.9 mA at 120 Hz (low frequency) and 459 mA at 200 kHz (high frequency) to support switching and high-frequency loads.
• Leakage current: Specified leakage current of 360 µA after standard application of rated voltage, enabling predictable standby and quiescent behavior.
• High-temperature endurance: Designed for 5,000 hours of life at +105°C (φ10 case), demonstrating long-term stability under elevated temperature stress.
• Compact radial package: Cylindrical can, diameter φ10 × length 30.5 mm with 5.0 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies.
• Packaging and production status: Available in bulk (no terminal forming) or bag packing and currently in mass production; RoHS compliant.

Typical Applications

• Switching Power Supplies: Low-impedance UPJ series construction and rated ripple current make this part well suited for output and bulk filtering in switching regulators.
• General-Purpose Power Filtering: Use on mid-voltage power rails up to 80 V for decoupling and energy storage in a variety of electronic equipment.
• Industrial and Communications Equipment: High-temperature endurance (5,000 h at 105°C) and predictable leakage behavior support long-life operation in industrial or communications power subsystems.

Unique Advantages

• Long operating life at high temperature: 5,000-hour endurance at +105°C for φ10 case sizes provides measurable reliability for designs that operate hot or require extended service intervals.
• Measured low loss: tan δ = 0.08 at 20°C/120 Hz (at rated voltage) keeps dissipation predictable in power applications, aiding thermal and efficiency planning.
• Dual-frequency ripple capability: Specified ripple currents at both 120 Hz and 200 kHz reflect usable performance across low- and high-frequency domains common in switched-mode supplies.
• Compact through-hole form factor: φ10 × 30.5 mm can with 5 mm lead spacing simplifies replacement and prototyping in through-hole boards while conserving board footprint.
• Regulatory compliance: RoHS-compliant construction supports environmental and procurement requirements.
