UPA1E102MHD3

The UPA1E102MHD3 is an aluminum electrolytic capacitor in a radial-can package designed for power filtering and decoupling in switching power supplies and general-purpose power applications. It combines a 1 mF capacitance with a 25 V rated voltage, low impedance and a compact footprint to support high-ripple, space-constrained designs.

Engineered for long-term operation at elevated temperature, this radial lead capacitor is RoHS compliant and specified for continuous use across a wide temperature range, making it suitable for industrial and embedded power subsystems.

Key Features

• Capacitance & Voltage — 1 mF nominal capacitance with a 25 V rated voltage and ±20% tolerance, providing predictable bulk storage for DC-DC converters and power rails.
• Low Impedance — Specified impedance of 58 mΩ to reduce ripple voltage and improve dynamic load response in switching supply outputs.
• High Ripple Handling — Ripple current capability of 1.417 A at 120 Hz and 1.89 A at 10 kHz to support a range of switching frequencies and smoothing applications.
• Compact Radial Package — Radial-can construction with 5 mm lead spacing and a small footprint (L: 2.0 cm × D: 1.25 cm), enabling dense PCB layouts.
• Wide Temperature Range — Rated for −55°C to +105°C operation to accommodate varied environmental conditions.
• Long Life at Elevated Temperature — Specified lifetime of 5000 hours at 105°C for sustained reliability in hot operating environments.
• RoHS Compliant — Meets RoHS directives as stated in the product series information.

Typical Applications

• Switching Power Supplies — Provides low-impedance bulk capacitance and high ripple current handling for output filtering and smoothing.
• DC-DC Converters — Used on converter outputs and intermediate stages to maintain stable voltage under dynamic load.
• General Purpose Power Filtering — Suitable for decoupling and energy storage in industrial and embedded power subsystems.

Unique Advantages

• Space-Saving Form Factor: Small radial-can dimensions let designers fit high capacitance into compact PCB areas without sacrificing ripple performance.
• Reduced Ripple Voltage: Low specified impedance (58 mΩ) and high ripple-current ratings lower voltage ripple and improve regulator stability.
• Durable at Elevated Temperatures: 5000-hour life at 105°C supports longevity in thermally demanding applications.
• Engineered for Power Applications: Polarized aluminum electrolytic construction and radial lead mounting make it straightforward to integrate into power supply designs.
• Regulatory Compliance: RoHS compliance simplifies use in regulated assemblies and helps meet environmental requirements.
