UPW1E561MPD

The UPW1E561MPD is a radial lead aluminum electrolytic capacitor in Nichicon’s UPW series, offering a compact, low-impedance solution for power filtering in switching power supplies and related electronics. It delivers 560 µF capacitance at a 25 V rating with a miniature φ10 × 20 mm can and standard radial lead mounting.

Designed for robust operation across a wide temperature range and long endurance, the part targets applications that require stable capacitance, high ripple-current handling, and AEC-Q200-rated reliability for automotive and industrial environments.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, suitable for bulk decoupling and smoothing in power rails.
• Low Impedance: Rated impedance of 104 mΩ, providing reduced ripple and improved transient response in converter outputs.
• High Ripple Current Capability: Low-frequency ripple current of 915 mA at 120 Hz and high-frequency ripple current of 1.22 A at 10 kHz, enabling use in both line-frequency and high-frequency switching environments.
• Loss Characteristic (tan δ): tanδ of 0.14 measured at 20°C, 120 Hz, supporting predictable dissipation behavior in thermal budgets.
• Endurance & Temperature Range: Rated life of 5000 hours at 105°C and an operating temperature range of −55°C to +105°C for long-term reliability under elevated temperature stress.
• Package & Mechanical: φ10 × 20 mm radial can with 5.0 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) and bag packing options.
• Leakage Current: Specified leakage current of 420 µA after voltage application, providing predictable leakage performance for power designs.
• AEC-Q200 Rated: Built to an AEC-Q200 rating, supporting use in automotive electronic modules where that qualification is required.

Typical Applications

• Switching Power Supplies: Output and bulk filtering in DC–DC converters and SMPS where low impedance and high ripple capability improve regulation and stability.
• Automotive Electronics: Power filtering and decoupling in automotive modules; the AEC-Q200 rating supports integration into vehicle systems.
• Embedded Power Systems: Local energy storage and smoothing for embedded converters and regulator circuits that require compact, high-capacitance components.

Unique Advantages

• Compact, High-Capacity Form Factor: 560 µF in a φ10 × 20 mm can reduces board area compared with larger cans while retaining bulk energy storage.
• Engineered for Ripple Performance: Specified ripple current values at both low and high frequencies (915 mA @120 Hz, 1.22 A @10 kHz) allow designers to size capacitors for real switching workloads.
• Predictable Dissipation: Specified tanδ (0.14 at 20°C, 120 Hz) and leakage current (420 µA) provide measurable parameters for thermal and power-loss budgeting.
• Long Endurance at Elevated Temperature: 5000 hours at 105°C supports extended life in thermally demanding applications.
• AEC-Q200 Reliability: The AEC-Q200 rating aligns the component with automotive reliability expectations for systems requiring industry-recognized qualification.
• Standard Radial Mounting and Packaging Options: 5.0 mm lead spacing and bulk/bag packing facilitate straightforward assembly and inventory handling for production lines.
