UPW2A561MHD

The UPW2A561MHD is a miniature aluminum electrolytic capacitor in a radial can package, designed for use in switching power supplies and automotive electronics. It combines a 560 µF capacitance with a 100 V rated voltage and polarized radial-lead construction for board-level power filtering and energy storage.

Engineered for reliability in demanding environments, the device offers low impedance (136 mΩ), defined ripple current performance (1.028 A at 120 Hz, 1.37 A at 10 kHz), AEC-Q200 qualification, and an operating temperature range of −55 °C to 105 °C with an expected lifetime of 8,000 hours at 105 °C.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable for high-voltage rail filtering and energy storage.
• Low Impedance Performance: Specified impedance of 136 mΩ to reduce ripple and improve transient response in switching power stages.
• Ripple Current Capability: Rated ripple currents include 1.028 A at 120 Hz and 1.37 A at 10 kHz, reflecting usable performance across low and high-frequency power domains.
• Automotive-Grade Reliability: AEC-Q200 rating and 8,000 hours lifetime at 105 °C provide defined durability for automotive electronics.
• Wide Temperature Range: Operates from −55 °C to 105 °C, supporting a broad range of environmental conditions.
• Compact Radial Can Package: Radial lead mounting with 7.5 mm lead spacing and compact dimensions (L: 3.05 cm × D: 1.8 cm) for space-constrained board layouts.
• Leakage and Dissipation Characteristics: Datasheet specifies leakage current limit of 0.03CV (µA) after 1 minute at 20 °C and a rated tan δ consistent with the UPW series specifications (for 100 V, tan δ max. 0.08 at 120 Hz, 20 °C).

Typical Applications

• Switching Power Supplies: Bulk and output filtering to reduce ripple and stabilize voltage rails in DC–DC converters and SMPS modules.
• Automotive Electronic Control Units (ECUs): Power rail smoothing and energy buffering in systems where AEC-Q200 qualification and long-life at elevated temperature are required.
• Power Management Modules: Local decoupling and transient energy support for power regulation circuits operating up to 100 V.

Unique Advantages

• AEC-Q200 Qualification: Provides a documented automotive stress-rating baseline for designs targeting vehicle electronics.
• High Voltage Capability: 100 V rating enables use on higher-voltage rails without stacking or additional components.
• Low Impedance and High Ripple Tolerance: 136 mΩ impedance and specified ripple currents improve power-stage stability and thermal performance under ripple loading.
• Long High-Temperature Life: 8,000 hours at 105 °C supports designs requiring extended durability in elevated-temperature environments.
• Compact Footprint: Small can size with radial lead mounting and 7.5 mm lead spacing simplifies layout in constrained assemblies.
