UPT2P561MRD

The UPT2P561MRD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon’s UPT series designed for general-purpose, high-reliability applications. It combines a 560 µF capacitance with a 220 V rating and is optimized for circuits requiring sustained ripple handling and extended elevated-temperature life.

Typical use cases include power conversion and ballast-type applications where high ripple current capability, a compact radial-can package, and long-term endurance at elevated temperature are important design criteria.

Key Features

• Electrical Performance — 560 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance, suitable for high-voltage smoothing and energy storage in compact assemblies.
• High Ripple Current — Rated ripple current of 1.5 A at 120 Hz and 2.4 A at 10 kHz, providing improved filtering performance under AC ripple and switching conditions.
• Long Life at Elevated Temperature — Specified endurance of 5000 hours at 105 °C when subjected to DC bias plus rated ripple current, supporting sustained operation in thermally demanding environments.
• Wide Operating Temperature Range — Specified to operate from −40 °C to +105 °C for broad environmental compatibility.
• Radial Lead, Compact Can Package — Radial lead mounting with 1 cm lead spacing and a compact footprint (L: 5 × D: 2.2 cm), enabling straightforward through-hole assembly in space-constrained boards.
• RoHS Compliant — Meets RoHS requirements for lead-free environmental compliance.

Typical Applications

• Ballast and Lamp Drivers — Designed for ballast applications where the capacitor’s high ripple-current capability improves stability and lifetime under AC-driven loads.
• Power Supplies and Converters — Used for smoothing and bulk energy storage in high-voltage power conversion stages that require robust ripple handling.
• Industrial Electronics — Suitable for general-purpose industrial control electronics that need compact, long-life capacitors able to withstand elevated ambient temperatures.
• Filtering in High-Voltage Circuits — Effective for noise suppression and decoupling in high-voltage assemblies needing reliable capacitance and leakage characteristics.

Unique Advantages

• High Ripple Handling: Rated ripple currents at both low and high frequencies (1.5 A at 120 Hz, 2.4 A at 10 kHz) reduce heating and improve circuit stability under AC stress.
• Extended Elevated-Temperature Endurance: 5000-hour life rating at 105 °C gives designers predictable longevity in hot environments.
• Compact Radial Package: Small can dimensions with radial leads and 1 cm lead spacing simplify PCB layout and assembly for through-hole designs.
• Wide Temperature Range: −40 °C to +105 °C operating range supports deployment across a broad set of industrial and commercial conditions.
• Regulatory Compliance: RoHS compliance supports environmental and regulatory requirements for modern electronic products.
