UPA1A561MPD

The UPA1A561MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPA series designed for switching power supplies and general-purpose power filtering. It delivers a compact, low-impedance solution with high ripple-current capability in a miniature can-style package.

Key electrical characteristics include 560 µF capacitance at 10 V, an impedance of 180 mΩ, rated ripple currents up to 630 mA at 10 kHz, and a polarized radial-lead package with a 3.5 mm lead spacing. The part is RoHS compliant and specified for operation from −55°C to 105°C.

Key Features

• Electrical Performance — 560 µF nominal capacitance at 10 V with ±20% tolerance and a measured impedance of 180 mΩ for improved filtering in power applications.
• High Ripple Current — Rated ripple current of 472.5 mA at 120 Hz and 630 mA at 10 kHz to support switching power supply workloads.
• Miniature Radial Package — Compact can-style radial lead package with dimensions L: 1.15 × D: 0.8 cm and 3.5 mm lead spacing for space-constrained boards.
• Wide Temperature Range — Specified operating range from −55°C to 105°C for robust performance across ambient conditions.
• Durability at Elevated Temperature — Rated lifetime of 3000 hours at 105°C, suitable for sustained high-temperature operation per the UPA series endurance specification.
• RoHS Compliant — Meets RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple current capacity improve voltage stability and transient response.
• General-Purpose Power Filtering — Decoupling and smoothing in compact electronic modules that require a polarized aluminum electrolytic capacitor.
• Compact Power Modules — Where miniature footprint and radial-lead mounting simplify layout in tight assemblies.

Unique Advantages

• Low-Impedance Filtering: 180 mΩ impedance reduces AC ripple and improves filtering effectiveness in power rails.
• High Ripple Capability: Specified ripple currents up to 630 mA at 10 kHz accommodate switching-frequency stress common in modern power supplies.
• Space-Saving Form Factor: Small can dimensions (1.15 × 0.8 cm) and radial-lead package enable use in compact boards and modules.
• Wide Temperature Range and Endurance: −55°C to 105°C operating range with a 3000-hour rating at 105°C for reliable long-term operation under elevated temperatures.
• Regulatory Compliance: RoHS compliance supports environmental and regulatory requirements for commercial electronic products.
• Manufacturer Quality: Part of Nichicon’s UPA series, offering consistent characteristics for designers specifying series-class performance.
