UPW1V561MPD

The UPW1V561MPD is a miniature aluminum electrolytic capacitor from Nichicon's UPW series. It is a radial‑lead, polarized capacitor offering 560 µF capacitance at a 35 V rating with low impedance and a compact φ10 × 25 mm can.

Designed for high‑reliability power circuits, the part targets switching power supplies and automotive electronics (AEC‑Q200 rated), delivering bulk energy storage, low impedance performance, and extended endurance in space‑constrained designs.

Key Features

• Capacitance and Voltage — 560 µF nominal capacitance at a 35 V rated voltage with a tolerance of −20% to +20%.
• Low impedance — Rated impedance of 90 mΩ for improved transient response and stable supply rails.
• Ripple current capability — Low‑frequency ripple current 1.08 A (120 Hz) and high‑frequency ripple current 1.44 A (10 kHz) to support demanding switching loads.
• Loss characteristics — tanδ (DF) of 0.12 measured at 20°C, 120 Hz for predictable dissipation behavior.
• Wide temperature and endurance — Operating range −55°C to +105°C with a rated endurance of 5000 hours at 105°C.
• Radial lead package — φ10 × 25 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm) suitable for through‑hole assembly and bulk/bag packing options.
• AEC‑Q200 rated — Specified for high‑reliability applications including automotive electronics.
• Leakage current — Specified leakage current of 588 µA for predictable quiescent behavior after voltage application.

Typical Applications

• Switching power supplies — Bulk energy storage and smoothing for DC–DC converters and regulator outputs where low impedance and high ripple capability matter.
• Automotive electronic systems — Power rail filtering and decoupling in automotive electronics that require AEC‑Q200 rated components and extended thermal endurance.
• Space‑constrained power designs — Compact φ10 × 25 mm footprint for densely packed power modules and compact assemblies.

Unique Advantages

• AEC‑Q200 reliability: Qualification for automotive applications supports use in systems requiring standardized reliability.
• High ripple handling: Specified ripple currents of 1.08 A (120 Hz) and 1.44 A (10 kHz) enable the capacitor to handle dynamic loads in switching environments.
• Low impedance for stable delivery: 90 mΩ impedance and a 0.12 tanδ at 20°C/120 Hz help maintain stable voltage under transient conditions.
• Compact, through‑hole form factor: Radial lead can (φ10 × 25 mm) with 5 mm lead spacing supports traditional assembly methods while saving PCB area.
• Extended high‑temperature endurance: Rated for 5000 hours at 105°C for longevity in elevated ambient or heated enclosure environments.
• Predictable leakage behavior: Specified leakage current (588 µA) aids in power budgeting and system-level leakage estimates.
