UPA1V561MPD

The UPA1V561MPD is a miniature aluminum electrolytic capacitor from Nichicon’s UPA series, engineered for low impedance and high reliability in switching power supply applications. It is a radial‑lead, can‑style capacitor rated at 560 µF and 35 V, designed for general‑purpose power filtering where compact size and ripple handling are important.

Key performance characteristics include a wide operating temperature range of −55°C to 105°C, RoHS compliance, and a rated lifetime of 4000 hours at 105°C, offering durability for sustained high‑temperature operation.

Key Features

• Electrical Performance — 560 µF capacitance at 35 V with ±20% tolerance and polarized construction for bulk energy storage and decoupling.
• Low Impedance — Specified impedance of 70 mΩ, supporting reduced voltage ripple in switching power environments.
• High Ripple Current — Rated ripple current of 1.117 A at 120 Hz and 1.49 A at 10 kHz to handle switching and high‑frequency ripple components.
• Compact Radial Can — Miniature size L: 2 × D: 1 cm (20 × 10 mm) with 5 mm lead spacing and radial lead mounting for through‑hole PCB implementations.
• Wide Temperature and Long Life — Operating range −55°C to 105°C with a specified lifetime of 4000 hours at 105°C, suitable for sustained elevated‑temperature use.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk and output filtering to reduce ripple and stabilize voltage rails in switching regulators.
• General‑Purpose Power Filtering — Decoupling and smoothing in electronic equipment requiring compact, through‑hole capacitors.
• Temperature‑Sensitive Designs — Use in circuits that operate across −55°C to 105°C where long high‑temperature lifetime is required.

Unique Advantages

• Reduced Ripple Voltage: Low 70 mΩ impedance helps lower ripple under load, improving regulator performance.
• High Frequency Capability: Rated ripple current up to 1.49 A at 10 kHz supports modern switching topologies with high‑frequency components.
• Space‑Efficient Footprint: Miniature 20 × 10 mm can and 5 mm lead spacing save PCB area while retaining through‑hole reliability.
• Proven High‑Temperature Endurance: 4000 hours at 105°C provides measurable long‑term stability in elevated ambient conditions.
• Regulatory Compliance: RoHS compliance simplifies environmental conformity for commercial designs.
