UPA0J561MPD

The UPA0J561MPD is an aluminum electrolytic capacitor from Nichicon's UPA series, offered in a radial-lead can package. It provides 560 µF of capacitance at a rated voltage of 6.3 V with a polarized design intended for general-purpose circuits and switching power supply applications.

Designed for compact power electronics, the component combines a miniature case size and low impedance with rated ripple-current capability and a high-temperature endurance specification to support stable decoupling and smoothing in space-constrained designs.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance at a rated voltage of 6.3 V, tolerance ±20%.
• Low Impedance: Specified impedance of 180 mΩ for improved ripple suppression in power rails.
• High Ripple Current Capability: Rated ripple current of 472.5 mA at 120 Hz and 630 mA at 10 kHz, supporting switching supply load conditions.
• Compact Radial Can Package: Radial lead mounting with 3.5 mm lead spacing and package dimensions L: 1.15 × D: 0.8 cm for compact board layouts.
• Wide Operating Temperature: Rated for −55°C to +105°C to accommodate a broad range of operating environments.
• Endurance: 3000 hours at 105°C, providing predictable lifetime behavior under elevated temperature and ripple-stressed conditions.
• Compliance: RoHS compliant as specified by the product data.
• Polarized Design: Polar capacitor intended for DC decoupling and smoothing applications.

Typical Applications

• Switching Power Supplies: Bulk and output filtering where low impedance and rated ripple current reduce voltage ripple and improve regulator stability.
• General-Purpose Power Filtering: DC rail smoothing and decoupling in small power modules and board-level power systems.
• Space-Constrained Electronics: Compact radial can footprint and short lead spacing make this capacitor suitable for dense PCB layouts and tight enclosures.

Unique Advantages

• Miniature footprint for compact designs: Small case size (L: 1.15 × D: 0.8 cm) and 3.5 mm lead spacing enable placement in tight PCB real estate.
• Measurable low impedance: 180 mΩ impedance specification directly supports effective ripple attenuation on low-voltage rails.
• Frequency-targeted ripple capability: Explicit ripple-current ratings at 120 Hz (472.5 mA) and 10 kHz (630 mA) help designers assess performance across switching frequencies.
• Long endurance at elevated temperature: 3000 hours at 105°C gives a defined lifetime profile for thermal and ripple-stressed applications.
• Polarized radial-lead form factor: Traditional radial can construction simplifies through-hole assembly and mechanical retention in power assemblies.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements.
