UPW1A153MHD

The UPW1A153MHD from Nichicon is a high-reliability, miniature aluminum electrolytic capacitor in a radial lead can designed for power applications. It delivers 15,000 µF at 10 V in a compact φ18 × 40 mm package with 7.5 mm lead spacing.

Engineered for demanding environments, this UPW-series part offers low impedance, high ripple-current capability and long endurance (8,000 hours at 105°C), making it suitable for switching power supplies and automotive electronics where robust bulk capacitance and reliability are required.

Key Features

• High Capacitance, Low Voltage: 15,000 µF rated at 10 V provides substantial energy storage for bulk filtering and decoupling in compact footprints.
• Low Impedance: Specified impedance of 28 mΩ helps minimize voltage ripple and improve transient response in power rails.
• High Ripple Current Capability: Low-frequency ripple current 3.23 A (120 Hz) and high-frequency ripple current 3.8 A (10 kHz) support both line-frequency and switching-frequency applications.
• Long Endurance: Rated for 8,000 hours at 105°C, enabling extended life in high-temperature operating environments.
• Automotive-Grade Reliability: Rated to AEC-Q200, aligning the part for automotive and other reliability-focused applications.
• Radial Lead, Through-Hole Package: φ18 × 40 mm can with 7.5 mm lead spacing (±0.5 mm) and bulk/bag packing options for manual or wave assembly.
• Polarized with Defined Leakage and Tolerance: Polarized capacitor with leakage current specified at 4,500 µA and capacitance tolerance of −20% to +20%.

Typical Applications

• Switching Power Supplies: Bulk energy storage and output smoothing where low impedance and high ripple current handling reduce output ripple and improve regulation.
• Automotive Power Electronics: Energy buffering and smoothing in automotive systems, leveraging the AEC-Q200 rating and high-temperature endurance.
• DC–DC Converters: Input/output filtering and transient support for converters operating at switching frequencies up to and beyond 10 kHz.
• Embedded and Industrial Power Modules: Local bulk capacitance for industrial and embedded power supplies operating across −55°C to 105°C.

Unique Advantages

• High bulk capacitance in a compact can: 15,000 µF in a φ18 × 40 mm package reduces board space compared with multiple smaller capacitors.
• Low ESR/impedance performance: 28 mΩ impedance helps lower ripple voltage and heat generation under load.
• Designed for high ripple environments: Specified ripple currents at 120 Hz and 10 kHz cover both low- and high-frequency filtering needs.
• Extended high-temperature life: 8,000-hour endurance at 105°C supports reliable long-term operation in thermally stressed designs.
• Automotive-capable rating: AEC-Q200 rating supports use in vehicle electronics and other reliability-driven markets.
• Practical packaging and mounting: Radial lead, through-hole can with standard lead spacing simplifies assembly and replacement.
